A Picanol rapier loom Weft insertion at 15 seconds 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.
The term is also used for a set of yarns established before the interworking of weft yarns by some other method, such as finger manipulation, yielding wrapped or twined structures. Very simple looms use a spiral warp, in which the warp is made up of a single, very long yarn wound in a spiral pattern around a pair of sticks or beams. [7]
Its counterpart, silk serge, is used for linings. French serge is a softer, finer variety. The word is also used for a high quality woolen woven. serging Serging is the binding off of an edge of cloth. sewing Sewing is an ancient craft involving the stitching of cloth, leather, animal skins, furs, or other materials, using needle and thread.
Weaving was known in all the great civilisations, but no clear line of causality has been established. Early looms required two people to create the shed and one person to pass through the filling. Early looms wove a fixed length of cloth, but later ones allowed warp to be wound out as the fell progressed.
A rapier loom is a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by finger-like carriers called rapiers. [1] A stationary package of yarn is used to supply the weft yarns in the rapier machine. One end of a rapier, a rod or steel tape, carries the weft yarn.
Handweaving looms (including floor and table looms) use interchangeable reeds, where the reeds can vary in width and dents per inch. This allows the same loom to be used for making both very fine and very coarse fabric, as well as weaving threads at dramatically different densities. [10] The width of the reed sets the maximum width of the warp. [4]
The derivation of the word is uncertain. [4] Inkle weaving is commonly used for narrow work such as trims, straps and belts. Inkle weaving is done on a loom known as an inkle loom. One key element that differentiates inkle looms from other band looms is that a continuous warp is required. [5]: 1
Originally, power looms used a shuttle to throw the weft across, but in 1927 the faster and more efficient shuttleless loom came into use. Sulzer Brothers, a Swiss company had the exclusive rights to shuttleless looms in 1942, and licensed the American production to Warner & Swasey. Draper licensed the slower rapier loom.
