A '''loom''' is a device used to [[weaving|weave]] cloth and tapestry. The basic purpose of any loom is to hold the [[Warp (weaving)|warp]] threads under [[tension (mechanics)|tension]] to facilitate the interweaving of the [[weft]] threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same.

==Etymology and usage==
The word "loom" derives from the [[Old English]] ''geloma'', formed from ''ge-'' (perfective prefix) and ''loma'', a root of unknown origin; the whole word ''geloma'' meant a utensil, tool, or machine of any kind.  In 1404 "lome" was used to mean a machine to enable weaving thread into cloth.<ref>{{oed | loom}}</ref><ref>{{cite web|url=http://www.etymonline.com/index.php?term=loom|title=loom - Origin and meaning of loom by Online Etymology Dictionary|website=www.etymonline.com}}</ref>{{failed verification|date=February 2022}}
By 1838 "loom" had gained the additional meaning of a machine for interlacing thread.{{cn|date=February 2022}}

===Basic structure===
Weaving is done on two sets of threads or yarns, which cross one another. The [[Warp (weaving)|warp]] threads are the ones stretched on the loom (from the [[Proto-Indo-European]] *''[[:wiktionary:warp|werp]]'', "to bend"<ref>{{cite web|url=http://www.etymonline.com/index.php?allowed_in_frame=0&search=warp|title=warp - Search Online Etymology Dictionary|website=www.etymonline.com}}</ref>). Each thread of the [[weft]] (i.e. "that which is woven") is inserted so that it passes over and under the warp threads.

The ends of the warp threads are usually fastened to beams. One end is fastened to one beam, the other end to a second beam, so that the warp threads all lie parallel and are all the same length. The beams are held apart to keep the warp threads taut. 

The textile is woven starting at one end of the warp threads, and progressing towards the other end. The beam on the finished-fabric end is called the ''cloth beam''. The other beam is called the ''warp beam''. 

Beams may be used as rollers to allow the weaver to weave a piece of cloth longer than the loom. As the cloth is woven, the warp threads are gradually unrolled from the warp beam, and the woven portion of the cloth is rolled up onto the cloth beam (which is also called the ''takeup roll''). The portion of the fabric that has already been formed but not yet rolled up on the takeup roll is called the ''fell''. 

Not all looms have two beams. For instance, warp-weighted looms have only one beam; the warp yarns hang from this beam. The bottom ends of the warp yarns are tied to dangling loom weights.

===Motions===
[[File:Belarus weaving.jpg|thumb|Passing the [[Shuttle (weaving)|shuttle]] through the shed]]
A loom has to perform three '''principal motions''': shedding, picking, and battening. 

*'''Shedding'''. Shedding is pulling part of the [[warp (weaving)|warp]] threads aside to form a [[shed (weaving)|shed]] (the space between the raised and unraised warp yarns). The shed is the space through which the filling yarn, carried by the shuttle, can be inserted, forming the weft. 
**Sheds may be simple: for instance, lifting all the odd threads and all the even threads alternately produces a [[tabby weave]] (the two sheds are called the shed and countershed). More intricate shedding sequences can produce more complex weaves, such as [[twill weave|twill]].
*'''Picking'''. A single crossing of the weft thread from one side of the loom to the other, through the shed, is known as a pick. Picking is passing the weft through the shed. A new shed is then formed before a new pick is inserted. 
**Conventional shuttle looms can operate at speeds of about 150 to 160 picks per minute.<ref name="Collier 1970 104">{{harvnb|Collier|1970|p=104}}.</ref>
*'''Battening'''. After the pick, the new pass of weft thread has to be tamped up against the fell, to avoid making a fabric with large, irregular gaps between the weft threads. This compression of the weft threads is called battening.

There are also usually two '''secondary motions''', because the newly constructed fabric must be wound onto cloth beam. This process is called taking up. At the same time, the warp yarns must be let off or released from the warp beam, unwinding from it. To become fully automatic, a loom needs a '''tertiary motion''', the filling stop motion. This will brake the loom if the weft thread breaks.<ref name="Collier 1970 104"/> An automatic loom requires 0.125&nbsp;hp to 0.5&nbsp;hp to operate.

===Components===
A loom, then, usually needs two beams, and some way to hold them apart. It generally has additional components to make shedding, picking, and battening faster and easier. There are also often components to help take up the fell.

The nature of the loom frame and the shedding, picking, and battening devices vary. Looms come in a wide variety of types, many of them specialized for specific types of weaving. They are also specialized for the lifestyle of the weaver. For instance, nomadic weavers tend to use lighter, more portable looms, while weavers living in cramped city dwellings are more likely to use a tall upright loom, or a loom that folds into a narrow space when not in use.

==Frames==
Loom frames can be roughly divided, by the orientation of the warp threads, into horizontal looms and vertical looms. There are many finer divisions. Most handlooom frame designs can be constructed fairly simply.<ref>{{cite book |url=http://www.cd3wd.com/cd3wd_40/vita/handloom/en/handloom.htm |title=Handloom Construction: A Practical Guide for the Non-Expert |first=Joan |last=Koster |date=1978 |publisher= Volunteers in Technical Assistance, Inc. |archive-url=https://web.archive.org/web/20140302081647/http://www.cd3wd.com/cd3wd_40/vita/handloom/en/handloom.htm |archive-date=2 March 2014 |url-status=dead}}</ref>

===Backstrap loom===
The back-strap loom (also known as belt loom)<ref>{{cite journal|last=Kent |first=Kate P.|title=The Cultivation and Weaving of Cotton in the Prehistoric Southwestern United States |journal=Transactions of the American Philosophical Society |volume=47|issue=3 |page=485 |date=1957 |doi=10.2307/1005732 |language=en |jstor=1005732|hdl=2027/mdp.39015017458095 |hdl-access=free }}</ref> is a simple loom with ancient roots, still used in many cultures around the world (such as [[Andean textiles]]). It consists of two sticks or bars between which the warps are stretched. One bar is attached to a fixed object and the other to the weaver, usually by means of a strap around the weaver's back. The weaver leans back and uses their body weight to tension the loom.

Both simple and complex textiles can be woven on backstrap looms. They produce [[narrowcloth]]: width is limited to the weaver's armspan. They can readily produce [[warp-faced]] textiles, often decorated with intricate pick-up patterns woven in complementary and [[supplementary warp]] techniques, and brocading. [[Balanced weave]]s are also possible on the backstrap loom.

===Warp-weighted loom===
[[File:Warp-weighted loom twill.jpg|thumb|[[Warp-weighted loom]] with three heddle-rods for weaving [[twill]]]]
{{main|Warp-weighted loom}}
The [[warp-weighted loom]] is a vertical loom that may have originated in the [[Neolithic]] period. Its defining characteristic is hanging weights (loom weights) which keep bundles of the [[Warp (weaving)|warp]] threads taut. Frequently, extra warp thread is wound around the weights. When a weaver has woven far enough down, the completed section (fell) can be rolled around the top beam, and additional lengths of warp threads can be unwound from the weights to continue. This frees the weaver from vertical size constraint. Horizontally, breadth is limited by armspan; making [[broadwoven cloth]] requires two weavers, standing side by side at the loom.

Simple weaves, and complex weaves that need more than two different sheds, can both be woven on a warp-weighted loom. They can also be used to produce tapestries.

===Pegged or floor loom===

In pegged looms, the beams can be simply held apart by hooking them behind pegs driven into the ground, with wedges or lashings used to adjust the tension. Pegged looms may, however, also have horizontal sidepieces holding the beams apart.

Such looms are easy to set up and dismantle, and are easy to transport, so they are popular with nomadic weavers. They are generally only used for comparatively small woven articles.<ref name="Edwards, 1952">{{cite book|last1=Edwards|first1=A.

The earliest evidence of a horizontal loom is found on a pottery dish in [[ancient Egypt]], dated to 4400 BC. It was a frame loom, equipped with treadles to lift the warp threads, leaving the weaver's hands free to pass and beat the weft thread.<ref>{{cite book |last1=Bruno |first1=Leonard C. |last2=Olendorf |first2=Donna |title=Science and technology firsts |date=1997 |publisher=[[Gale Research]] |isbn=9780787602567 |page=[https://archive.org/details/sciencetechnolog0000brun/page/2 2] |url=https://archive.org/details/sciencetechnolog0000brun |url-access=registration |quote=4400 B.C. Earliest evidence of the use of a horizontal loom is its depiction on a pottery dish found in Egypt and dated to this time. These first true frame looms are equipped with foot pedals to lift the warp threads, leaving the weaver's hands free to pass and beat the weft thread.}}</ref>

A pit loom has a pit for the treadles, reducing the stress transmitted through the much shorter frame.<ref name="Know Your Handlooms"/>

In a wooden vertical-shaft loom, the [[heddle]]s are fixed in place in the shaft. The warp threads pass alternately through a heddle, and through a space between the heddles (the [[shed (weaving)|shed]]), so that raising the shaft raises half the threads (those passing through the heddles), and lowering the shaft lowers the same threads — the threads passing through the spaces between the heddles remain in place.

A treadle loom for figured weaving may have a large number of harnesses or a control head. It can, for instance, have a [[Jacquard machine]] attached to it<ref>{{Cite web|url=https://artless-store.com/blogs/the-artless-way/handloom-vs-powerloom|archive-url = https://web.archive.org/web/20201201174856/https://artless-store.com/blogs/the-artless-way/handloom-vs-powerloom|archive-date = 2020-12-01|title = Handloom VS Powerloom|date = 19 March 2020}}</ref> {{see above|Loom#Shedding methods}}.

===Tapestry looms===
{{main|tapestry}}
Tapestry can have extremely complex wefts, as different strands of wefts of different colours are used to form the pattern. Speed is lower, and shedding and picking devices may be simpler. Looms used for weaving traditional [[tapestry]] are called not as "vertical-warp" and "horizontal-warp", but as "high-warp" or "low-warp" (the French terms ''[[Warp (weaving)|haute-lisse]]'' and {{transliteration|fr|basse-lisse}} are also used in English).<ref>https://www.merriam-webster.com/dictionary/bas-lisse and the other 3 entries</ref>

===Ribbon, Band, and Inkle weaving===
{{main|Inkle weaving}}
Inkle looms are narrow looms used for [[narrow work]]. They are used to make narrow [[warp-faced]] strips such as ribbons, bands, or tape. They are often quite small; some are used on a tabletop. others are backstraps looms with a rigid [[heddle]], and very portable.

===Darning looms===
{{main|Darning loom}}
There exist very small hand-held looms known as darning looms. They are made to fit under the fabric being mended, and are often held in place by an elastic band on one side of the cloth and a groove around the loom's darning-egg portion on the other. They may have heddles made of flip-flopping rotating hooks {{see above|[[Loom#Rotating-hook heddles]]}}.<ref>On darning loom function:

===Circular handlooms===
<!-- Deleted image removed: [[File:Six shuttle circular loom machine.jpg|thumb|typical circular loom]] -->
Circular looms are used to create seamless tubes of fabric for products such as hosiery, sacks, clothing, fabric hoses (such as fire hoses) and the like. [[Tablet weaving]] can be used to knit tubes, including tubes that split and join.

Small jigs also used for [[circular knitting]] can be used as circular looms.<ref>{{cite video |url=https://www.youtube.com/watch?v=XIA53WfVv04 | archive-url=https://ghostarchive.org/varchive/youtube/20211114/XIA53WfVv04| archive-date=2021-11-14 | url-status=live|via=YouTube |title=How to: Cast on/Knit using a Circular Loom |author=Jocelyn C. |date=22 December 2008 |access-date=27 June 2016}}{{cbignore}}</ref>

==Shedding methods==
[[File:WEAVING WITH A PIN (cropped).jpg|thumb|upright=1.7|[[Pin weaving]], not using any shedding devices. Note hair comb, presumably used to beat the warp against the fell.]]
{{main|Shed (weaving)}}
It is possible to weave by manually threading the weft over and under the warp threads, but this is slow. Some tapestry techniques use manual shedding. [[Pin loom]]s and [[peg loom]]s also generally have no shedding devices. [[Pile carpet]]s generally do not use shedding for the pile, because each pile thread is individually knotted onto the warps, but there may be shedding for the weft holding the carpet together.

Usually weaving uses shedding devices. These devices pull some of the warp threads to each side, so that a shed is formed between them, and the weft is passed through the shed. There are a variety of methods for forming the shed. At least two sheds must be formed, the shed and the countershed. Two sheds is enough for [[tabby weave]]; more complex weaves, such as [[twill weave]]s, [[satin weave]]s, [[diaper weave]]s, and figured (picture-forming) weaves, require more sheds.

===Shed-rod===
[[File:VerticalLoom.JPG|thumb|Loom with a shed bar and without a string heddle, neolithic reconstruction in the [[Piatra Neamț]] Museum]]
A shed-rod (shedding stick, shed roll) is simply a stick woven through the warp threads. When pulled perpendicular to the threads (or rotated to stand on edge, for wide, flat shedding rods), it creates a shed. To create the counter-shed, a heddle-bar is usually used.

===Heddle-bar===

[[File:Lisses du métier à tisser.jpg|thumb|Heddle-rod on a tapestry frame, France, 2018]]
A heddle-bar is simply a stick placed across the warp and tied to individual warp threads. When it is lifted, it pulls the warp threads it is tied to out of position, creating a shed.

A [[warp-weighted loom]] (see diagram) typically uses a heddle-bar. It has two upright ''posts'' (C); they support a horizontal ''beam'' (D), which is cylindrical so that the finished cloth can be rolled around it, allowing the loom to be used to weave a piece of cloth taller than the loom, and preserving an ergonomic working height. The warp threads (F, and A and B) hang from the beam and rest against the ''shed rod'' (E). The ''heddle-bar'' (G) is tied to some of the warp threads (A, but not B), usign loops of string called ''leashes'' (H). So when the heddle rod is pulled out and placed in the forked sticks protruding from the posts (not lettered, no technical term given in citation), the ''shed'' (1) is replaced by the ''counter-shed'' (2). By passing the weft through the shed and the counter-shed, alternately, cloth is woven.<ref name="Pakenham"/>

Heddle-rods are used on modern tapestry looms.

===Tablet weaving===
{{main|tablet weaving}}
[[File:Tablet-weaving.svg|thumb|upright=1.2|Simple one-tablet weaving]]
[[Tablet weaving]] uses cards punched with holes. The warp threads pass through the holes, and the cards are twisted and shifted to created varied sheds. This shedding technique is used for [[narrow work]]. It is also used to finish edges, weaving decorative selvage bands instead of hemming.

===Rotating-hook heddles===
{{main|Darning loom}}
[[File:Spede+Weve+Miniature+Loom+Model+1+Instructions (cropped to illustration).jpg|thumb|alt=A tiny loom with a heddle made of rotating hooks.|Darning loom with hook heddle]]
There are heddles made of flip-flopping rotating hooks, which raise and lower the warp, creating [[shed (weaving)|sheds]]. The hooks, when vertical, have the weft threads looped around them horizontally. If the hooks are flopped over on side or another, the loop of weft twists, raising one or the other side of the loop, which creates the [[shed (weaving)|shed]] and countershed.<ref>{{cite web |title=Darning Mini Wooden Loom Machine |url=https://www.miupie.com/Darning-Mini-Wooden-Loom-Machine-p3176174.html |website=Miupie |language=en}} (commercial site, but with animation showing how it works), {{cite web |last1=Morley |first1=Jasmin |title=Darning Loom Instructions |url=https://purlandfriends.com/blogs/news/darning-loom-instructions |website=Purl and Friends |access-date=7 January 2023 |date=8 September 2022}}, {{cite web |first1=Allison |last1=[not given] |title=Darning loom |url=https://ontheneedles.com/tag/darning-loom/ |website=On the Needles |date=27 December 2021 |access-date=7 January 2023 |language=en}}, {{cite web |title=How To Use A 1940s "Speed weve" Darner [repost of original 1940s instruction manual]|url=https://ragandmagpie.co.uk/blog/how-to-use-a-1940s-speede-weve |website=Rag & Magpie |date=16 April 2014 |access-date=9 December 2022}}</ref>

The triangular areas have simple, rough incised carving.|A rigid heddle on a backstrap [[inkle loom]], unspanned.]]

Rigid [[heddle]]s are generally used on single-shaft looms. Odd warp threads go through the slots, and even ones through the circular holes, or vice-versa. The shed is formed by lifting the heddle, and the countershed by depressing it. The warp threads in the slots stay where they are, and the ones in the circular holes are pulled back and forth. A single rigid heddle can hold all the warp threads, though sometimes multiple rigid heddles are used.

Treadles may be used to drive the rigid heddle up and down.

===Multiple heddles===
[[File:BogolanMali32.JPG|thumb|upright=2|This loom has two string heddles, connected via a pulley overhead so that they rise and fall alternately. They are operated by treadles. Each treadle is a [[button#toggle|toggle]] on a string, held in the weaver's toes. He is making a simple [[tabby-weave]] cloth, [[bogolan]].]]

Rigid heddles (above) are called "rigid" to distinguish them from string and metal heddles, where each warp thread has its own heddle, which has an eye at each end and one in the middle for the warp thread. The eyes in the ends are fastened to a shaft, all in a row. This requires multiple shafts; it cannot be done on a single-shaft loom. The different shafts (also called harnesses) must be controlled by some mechanism.

While non-rigid heddles generally mean that two shafts are needed even for a plain [[tabby weave]], [[twill weave]]s require three or more (depending on the type of twill), and more complex figured weaves require still more harnesses.

====Treadle-controlled looms====
Treadle looms can control multiple harnessess with multiple treadles. The weaver selects which harnesses are engaged with their feet. One treadle may be connected to more than one harness, and any number of treadles can be engaged at once, meaning that the number of different sheds that can be selected is two [[to the power of]] the number of treadles. Eight is a large but reasonable number of treadles, giving a maximum of 2<sup>8</sup>=256 sheds (some of which will not have enough threads on one side to be useful). The weaver must remember the sequence of treadling needed to produce the pattern.

====Figure harness and the drawloom====
{{anchor|Drawloom|Figure harness}}

A drawloom is for weaving figured cloth. In a drawloom, a "figure harness" is used to control each warp thread separately,{{sfn|Burnham|1980|p=48}} allowing very complex patterns. A drawloom requires two operators, the weaver, and an assistant called a "drawboy" to manage the figure harness.

The earliest confirmed drawloom fabrics come from the [[Chu (state)|State of Chu]] and date c. 400 BC.<ref name="broudy 1979 124">{{harvnb|Broudy|1979|p=124}}.</ref> Some scholars speculate an independent invention in ancient [[Syria]], since drawloom fabrics found in [[Dura-Europas]] are thought to date before 256 AD.<ref name="broudy 1979 124"/>{{sfn|Forbes|1987|pp=218, 220}} The draw loom was invented in China during the Han dynasty ([[State of Liu]]?);{{contradictory inline|reason=that was two centuries later, minimum|date=January 2023}}<ref name="auto">{{Cite book |title=Explorations in the History of Machines and Mechanisms: Proceedings of HMM2012 (History of Mechanism and Machine Science) |url=https://archive.org/details/explorationshist00moon |url-access=limited |last1= Ceccarelli |first1= Marco |last2=López-Cajún |first2=Carlos  |year=2012 |publisher=Springer |pages=[https://archive.org/details/explorationshist00moon/page/n226 219]–220 |isbn=978-9400799448}}</ref> foot-powered multi-harness looms and jacquard looms were used for silk weaving and embroidery, both of which were cottage industries with imperial workshops.<ref>{{Cite book |title=A History of Mechanical Inventions |last= Usher |first= Abbott Payson |year=2011 |publisher= Dover Publications |page=54 |isbn=978-0486255934}}</ref> The drawloom enhanced and sped up the production of silk and played a significant role in Chinese silk weaving.

====Dobby head====
[[File:Hand loom Weaving in Hooghly District 17.jpg|thumb|upright=2|Dobby-loom control mechanism. The pegs driven into the bars (hung in a loop on the left) each lift one "treadle" in a pre-determined pattern, like lifting the teeth of a [[music box]]. Hooghly District, West Bengal, 2019]]
{{main|dobby loom}}
A dobby head is a device that replaces the drawboy, the weaver's helper who used to control the warp threads by pulling on draw threads. "Dobby" is a corruption of "draw boy". Mechanical dobbies pull on the draw threads using pegs in bars to lift a set of levers. The placement of the pegs determines which levers are lifted. The sequence of bars (they are strung together) effectively remembers the sequence for the weaver. Computer-controlled dobbies use [[solenoid]]s instead of pegs.

====Jacquard head====
{{main|Jacquard loom}}
The '''Jacquard loom''' is a mechanical loom, invented by [[Joseph Marie Jacquard]] in 1801, which simplifies the process of manufacturing figured [[textiles]] with complex patterns such as [[Brocade (fabric)|brocade]], [[damask]] and [[matelasse]].<ref>{{cite book |first=Eric |last=Hobsbawm |title=The Age of Revolution |location=London |orig-year=1962 |date=2008 |page=45}}</ref><ref>{{cite web|url=http://www.christinalynn.com/fabric-glossary.shtml |title=Fabric Glossary |work=Christina Lynn |access-date=21 November 2008 |url-status=dead |archive-url=https://web.archive.org/web/20090105170019/http://www.christinalynn.com/fabric-glossary.shtml |archive-date=5 January 2009 }}</ref> The loom is controlled by [[punched card]]s with punched holes, each row of which corresponds to one row of the design. Multiple rows of holes are punched on each card and the many cards that compose the design of the textile are strung together in order. It is based on earlier inventions by the Frenchmen [[Basile Bouchon]] (1725), Jean Baptiste Falcon (1728) and [[Jacques Vaucanson]] (1740).{{sfn|Razy|1913|p=120}} To call it a loom is a misnomer, a Jacquard head could be attached to a power loom or a handloom, the head controlling which warp thread was raised during shedding. Multiple shuttles could be used to control the colour of the weft during picking.  The Jacquard loom is the predecessor to the [[Punched card input/output|computer punched card reader]]s of the 19th and 20th centuries.<ref>{{cite news|last1=Geselowitz|first1=Michael N.|title=The Jacquard Loom: A Driver of the Industrial Revolution|url=http://theinstitute.ieee.org/tech-history/technology-history/the-jacquard-loom-a-driver-of-the-industrial-revolution|work=The Institute: The IEEE news source|access-date=31 March 2018|date=18 July 2016|publisher=IEEE|archive-url=https://web.archive.org/web/20180401074908/http://theinstitute.ieee.org/tech-history/technology-history/the-jacquard-loom-a-driver-of-the-industrial-revolution|archive-date=1 April 2018|url-status=dead}}</ref>

==Picking (weft insertion)==
{{anchor|Weft insertion|picking}}

<!--[[File:History of Inventions USNM 30 Shuttle.png|thumb|A selection of shuttles.]]-->
The weft may be passed across the shed as a ball of yarn, but usually this is too bulky and unergonomic. Shuttles are designed to be slim, so they pass through the shed; to carry a lot of yarn, so the weaver does not need to refill them too often; and to be an ergonomic size and shape for the particular weaver, loom, and yarn. They may also be designed for low friction.

===Stick shuttles===

At their simplest, these are just sticks wrapped with yarn. They may be specially shaped, as with the bobbins and bones used in tapestry-making (bobbins are used on vertical warps, and bones on horizontal ones).<ref>{{cite web |title=Tapestry Weaving with Soumak |url=https://betweenandetc.com/product/tapestry-weaving-with-soumak/ |website=Between and Etc.}}</ref><ref>{{cite book |last1=Churchill Candee |first1=Helen |title=The Tapestry Book |date=1912 |publisher=Fredrick A.

Hand weavers who threw a shuttle could only weave [[narrow cloth|a cloth as wide as their armspan]]. If cloth needed to be wider, two people would do the task (often this would be an adult with a child). [[John Kay (flying shuttle)|John Kay]] (1704–1779) patented the [[flying shuttle]] in 1733. The weaver held a picking stick that was attached by cords to a device at both ends of the shed. With a flick of the wrist, one cord was pulled and the shuttle was propelled through the shed to the other end with considerable force, speed and efficiency. A flick in the opposite direction and the shuttle was propelled back. A single weaver had control of this motion but the flying shuttle could weave much wider fabric than an arm's length at much greater speeds than had been achieved with the hand thrown shuttle.

The ''flying shuttle'' was one of the key developments in [[weaving]] that helped fuel the [[Industrial Revolution]]. The whole picking motion no longer relied on manual skill and it was just a matter of time before it could be powered by something other than a human.

===Weft insertion in power looms===

[[File:1906 Toyoda Circular Loom.jpg|thumb|1906 Toyoda circular weaving loom]]
Different types of power looms are most often defined by the way that the weft, or pick, is inserted into the warp. Many advances in weft insertion have been made in order to make manufactured cloth more cost effective. Weft insertion rate is a limiting factor in production speed. {{asof|2010}}, industrial looms can weave at 2,000 [[weft|weft insertion]]s per minute.<ref>{{cite web |first=S. |last=Rajagopalan |title=Advances in Weaving Technology and Looms |publisher=S.S.M. College of Engineering, Komarapalayam |url=http://www.pdexcil.org/news/40N1002/advances.htm |via=Pdexcil.org |archive-url=https://web.archive.org/web/20101129031824/http://www.pdexcil.org/news/40N1002/advances.htm |archive-date=29 November 2010 |url-status=dead}}</ref>

There are five main types of weft insertion and they are as follows:
* Shuttle: The first-ever powered looms were shuttle-type looms. Spools of weft are unravelled as the shuttle travels across the shed. This is very similar to projectile methods of weaving, except that the weft spool is stored on the shuttle. These looms are considered obsolete in modern industrial fabric manufacturing because they can only reach a maximum of 300 picks per minute.
* Air jet: An [[Air jet loom|air-jet loom]] uses short quick bursts of compressed air to propel the weft through the shed in order to complete the weave. Air jets are the fastest traditional method of weaving in modern manufacturing and they are able to achieve up to 1,500 picks per minute. However, the amounts of compressed air required to run these looms, as well as the complexity in the way the air jets are positioned, make them more costly than other looms. 
* Water jet: Water-jet looms use the same principle as air-jet looms, but they take advantage of pressurized water to propel the weft. The advantage of this type of weaving is that water power is cheaper where water is directly available on site. Picks per minute can reach as high as 1,000. 
* [[Rapier loom]]: This type of weaving is very versatile, in that rapier looms can weave using a large variety of threads.  There are several types of rapiers, but they all use a hook system attached to a rod or metal band to pass the pick across the shed. These machines regularly reach 700 picks per minute in normal production.
* Projectile: [[Projectile loom]]s utilize an object that is propelled across the shed, usually by spring power, and is guided across the width of the cloth by a series of reeds. The projectile is then removed from the weft fibre and it is returned to the opposite side of the machine so it can be reused. Multiple projectiles are in use in order to increase the pick speed. Maximum speeds on these machines can be as high as 1,050 ppm.
* Circular:  Modern circular looms use up to ten shuttles, driven in a circular motion from below by electromagnets, for the weft yarns, and cams to control the warp threads. The warps rise and fall with each shuttle passage, unlike the common practice of lifting all of them at once. Circular looms are used to create seamless tubes of fabric for products such as hosiery, sacks, clothing, fabric hoses (such as fire hoses) and the like.<ref>{{cite web |url=http://www.starlinger.com/en/packaging/circular-looms/ |work=Starlinger |title=Circular Looms |access-date=27 June 2016}}</ref>

</gallery>

The newest weft thread must be beaten against the fell. Battening can be done with a long stick placed in the shed parallel to the weft (a sword batten), a shorter stick threaded between the warp threads perpendicular to warp and weft (a pin batten), a comb, or a reed (a comb with both ends closed, so that it has to be sleyed, that is have the warp threads threaded through it, when the loom is warped). For rigid-heddle looms, the heddle may be used as a reed.

==Secondary motions==
===Dandy mechanism===
{{main|dandy loom}}
Patented in 1802, [[dandy loom]]s automatically rolled up the finished cloth, keeping the fell always the same length. They significantly speeded up hand weaving (still a major part of the textile industry in the 1800s). Similar mechanisms were used in power looms.

===Temples===
[[File:QSMM Butterworth & Dickinson Loom 2681.JPG|thumb|A temple on a loom]]
{{main|temple (weaving)}}
The temples act to keep the cloth from shrinking sideways as it is woven. Some warp-weighted looms had temples made of [[loom weight]]s, suspended by strings so that they pulled the cloth breadthwise.<ref name=Pakenham/> Other looms may have temples tied to the frame, or temples that are hooks with an adjustable shaft between them. Power looms may use temple cylinders.<!--, which have helical grips and act like soft [[worm gears]].accurate?--> Pins can leave a series of holes in the [[selvage]]s (these may be from [[stenter|stenter pin]]s used in post-processing).

==Handlooms to power looms==
{{anchor|handloom}}
{{Main|Power loom}}

A power loom is a loom powered by a source of energy other than the weaver's muscles. When power looms were developed, other looms came to be referred to as ''handlooms''. Most cloth is now woven on power looms, but some is still woven on handlooms.<ref name="Know Your Handlooms">{{Cite web |date=2020-10-18 |title=Know Your Handlooms |url=https://dastkarandhra.com/know/know-your-handlooms/ |access-date=2022-03-24 |website=DAMA Handloom Store |language=en-US}}</ref>

The development of power looms was gradual. The capabilities of power looms gradually expanded, but handlooms remained the most cost-effective way to make some types of textiles for most of the 1800s. Many improvements in loom mechanisms were first applied to hand looms (like the [[dandy loom]]), and only later integrated into power looms.

[[Edmund Cartwright]] built and patented a [[power loom]] in 1785, and it was this that was adopted by the nascent cotton industry in England. The silk loom made by [[Jacques Vaucanson]] in 1745 operated on the same principles but was not developed further. The invention of the [[flying shuttle]] by [[John Kay (flying shuttle)|John Kay]] allow a hand weaver to weave [[broadwoven cloth]] without an assistant, and was also critical to the development of a commercially successful power loom.{{sfn|Marsden|1895|p=57}} Cartwright's loom was impractical but the ideas behind it were developed by numerous inventors in the Manchester area of England where, by 1818, there were 32 factories containing 5,732 looms.{{sfn|Guest|1823|p=46}}

The [[Horrocks loom]] was viable, but it was the [[Roberts Loom]] in 1830 that marked the turning point.{{sfn|Marsden|1895|p=76}}{{clarify|date=January 2023}} Incremental changes to the three motions continued to be made. The problems of sizing, stop-motions, consistent take-up, and a [[Temple (weaving)|temple]] to maintain the width remained. In 1841, Kenworthy and [[Howard & Bullough|Bullough]] produced the [[Lancashire Loom]]{{sfn|Marsden|1895|p=94}} which was self-acting or semi-automatic. This enables a youngster to run six looms at the same time. Thus, for simple calicos, the power loom became more economical to run than the handloom – with complex patterning that used a dobby or Jacquard head, jobs were still [[domestic system|put out]] to handloom weavers until the 1870s. Incremental changes were made such as the [[Dickinson Loom]], culminating in the [[Keighley]]-born inventor Northrop, who was working for the [[Draper Corporation]] in [[Hopedale, Massachusetts|Hopedale]] producing the fully automatic [[Northrop Loom]]. This loom recharged the shuttle when the [[pirn]] was empty. The Draper E and X models became the leading products from 1909. They were challenged by synthetic fibres such as [[rayon]].{{sfn|Mass|1990}}

By 1942, faster, more efficient, and shuttleless [[Sulzer (manufacturer)|Sulzer]] and [[rapier loom]]s had been introduced.{{sfn|Collier|1970|p=111}}

== Symbolism and cultural significance ==

The loom is a symbol of [[Creation myth|cosmic creation]] and the structure upon which individual destiny is woven. This symbolism is encapsulated in the [[Classical mythology|classical myth]] of [[Arachne]] who was changed into a spider by the goddess [[Athena]], who was jealous of her skill at the godlike craft of weaving.<ref>{{cite book|last1=Tresidder|first1=Jack|title=The Hutchinson Dictionary of Symbols|date=1997|publisher=Helicon Publishers|location=London|isbn=1-85986-059-1|page=127}}</ref> In [[Maya civilization]] the goddess [[Ixchel]] taught the first woman how to weave at the beginning of time.<ref>{{cite journal|last1=Rosenbaum|first1=Brenda P.|title=Mayan Women, Weaving and Ethnic Identity: a Historical Essay|journal=Guatemala: Museo Ixchel del Traje Indigena|date=1990|pages=157–169}}</ref>
