The warp-beam is a wooden or metal cylinder on the back of the loom on which the warp is delivered. The threads of the warp extend in parallel order from the warp-beam to the front of the loom where they are attached to the cloth-roll. Each thread or group of threads of the warp passes through an opening (eye) in a heddle.
Passing the shuttle through the shed. A loom has to perform three principal motions: shedding, picking, and battening. Shedding. Shedding is pulling part of the warp threads aside to form a 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 ...
Inkle looms have one of the more primitive shedding devices, where there is one set of heddles and the shed is created by hand. A backstrap loom with a shed-rod. Originally there was no shed, and the weft was inserted into the warp by picking the warp threads up individually, as is done in tapestry weaving. After each weft thread is woven the ...
The heddle-bar (G) is tied to some of the warp threads (A, but not B), using 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 ...
The vertical warp yarns are held stationary in tension on a loom (frame) while the horizontal weft (also called the woof) is drawn through (inserted over and under) the warp thread. [1] In the terminology of weaving, each warp thread is called a warp end ; a pick is a single weft thread that crosses the warp thread (synonymous terms are fill ...
The heddles raise the warp to create the shed through which the shuttle carrying the weft will pass. [16] A loom with a 400-hook head might have four threads connected to each hook, resulting in a fabric that is 1600 warp ends wide with four repeats of the weave going across. The term "Jacquard loom" is somewhat inaccurate.
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.
Shedding is the raising of the warp yarns to form a loop through which the filling yarn, carried by the shuttle, can be inserted. The shed is the vertical space between the raised and unraised warp yarns. On the modern loom, simple and intricate shedding operations are performed automatically by the heddle or heald frame, also known as a harness.
