Industrial Weaving Looms
Loom is a machine which is used to produce woven fabric by interlacement of warp and weft yarn. Ginning, opening, cleaning, carding, combing, drawing, spinning, winding, warping, sizing, beaming are the process prior to weaving.
All these process converge on loom.
The basic purpose of any loom is to hold the warp threads under 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.
The major components of the loom are the warp beam, heddles, harnesses or shafts, shuttle, reed and takeup roll.
In the loom, yarn processing includes shedding, picking, battening and taking-up operations.
On the modern loom, shedding operations are performed automatically by the heddle or heald frame, also known as a harness. The yarns are passed through the holes of the heddles which hang vertically from the harnesses.
The weave pattern determines which harness controls which warp yarns, and the number of harnesses used depends on the complexity of the weave. Two common methods of controlling the heddles are dobbies and a Jacquard head.
