Rigid heddle loom

Posted on 27 октября, 2020 by minini

Not to be confused with Knitting machine. A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. In 1404 it was used to mean a machine to enable weaving thread into cloth. By 1838, it had gained the meaning of a machine for interlacing thread. Weaving is done by intersecting the longitudinal threads, the warp, i. In the loom, yarn processing includes shedding, rigid heddle loom, battening and taking-up operations.

As the harnesses raise the heddles or healds, which raise the warp yarns, the shed is created. The filling yarn is inserted through the shed by a small carrier device called a shuttle. The shuttle is normally pointed at each end to allow passage through the shed. In a traditional shuttle loom, the filling yarn is wound onto a quill, which in turn is mounted in the shuttle. The portion of the fabric that has already been formed but not yet rolled up on the takeup roll is called the fell.

Conventional shuttle looms can operate at speeds of about 150 to 160 picks per minute. There are two secondary motions, because with each weaving operation the newly constructed fabric must be wound on a cloth beam. This process is called taking up. At the same time, the warp yarns must be let off or released from the warp beams. To become fully automatic, a loom needs a tertiary motion, the filling stop motion. This will brake the loom if the weft thread breaks.

One bar is attached to the ceiling of the traditional T’boli longhouse, while the other is attached to the lower back. The back strap loom is a simple loom that has its roots in ancient civilizations. The Andes Textiles, still made today with the back strap loom, originated thousands of years ago with the same back strap loom process. It consists of two sticks or bars between which the warps are stretched. Both simple and complex textiles can be woven on this loom. Width is limited to how far the weaver can reach from side to side to pass the shuttle. Warp faced textiles, often decorated with intricate pick-up patterns woven in complementary and supplementary warp techniques are woven by indigenous peoples today around the world. They produce such things as belts, ponchos, bags, hatbands and carrying cloths.

Supplementary weft patterning and brocading is practiced in many regions. The warp-weighted loom is a vertical loom that may have originated in the Neolithic period. The earliest evidence of warp-weighted looms comes from sites belonging to the Starčevo culture in modern Serbia and Hungary and from late Neolithic sites in Switzerland. A drawloom is a hand-loom for weaving figured cloth. In a drawloom, a «figure harness» is used to control each warp thread separately. A drawloom requires two operators, the weaver and an assistant called a «drawboy» to manage the figure harness. A handloom is a simple machine used for weaving. In a wooden vertical-shaft looms, the heddles are fixed in place in the shaft.

Hand weavers could only weave a cloth as wide as their armspan. The weaver held a picking stick that was attached by cords to a device at both ends of the shed. 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. Looms used for weaving traditional tapestry are classified as haute-lisse looms, where the warp is suspended vertically between two rolls. In basse-lisse looms, however, the warp extends horizontally between the two rolls. Several other types of hand looms exist, including the simple frame loom, pit loom, free-standing loom, and the pegged loom. Each of these can be constructed, and provide work and income in developing economies.

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 foot pedals to lift the warp threads, leaving the weaver’s hands free to pass and beat the weft thread. A 1939 loom working at the Mueller Cloth Mill museum in Euskirchen, Germany. 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. Horrocks loom was viable, but it was the Roberts Loom in 1830 that marked the turning point. Incremental changes to the three motions continued to be made.

Different types of 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. 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 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.

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 looms 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.

A dobby loom is a type of floor loom that controls the whole warp threads using a dobby head. Dobby is a corruption of «draw boy» which refers to the weaver’s helpers who used to control the warp thread by pulling on draw threads.

Following the pattern, holes are punched in the appropriate places on a jacquard card. Manual loom with double width and jacquard loom, Colegio del Arte Mayor de la Seda of Valencia.
