Weaving

Woven fabric is normally much longer in the warp direction than it is wide, that is, in the weft direction. Warp yarns are fed from large reels called creels or beams. Typically, these hold about 4500 separate pieces of yarn, each about 500 yards (450 m) long. The filling yarns are fed from bobbins, called quills, carried in shuttles (hollow projectiles) that are moved back and forth across the warp yarns, passing over some and under others. The shuttle is designed so that the yarn it carries can unwind freely as the shuttle moves. Each length of yarn, fed from the shuttle as it moves across the loom, is called a pick. The yarn folds over itself at the end of each pick and forms another pick as the shuttle returns. When the yarn in a particular shuttle is exhausted, current production looms have automatic devices that exchange the empty quill with a full one.

Starting from the storehouse, the yarn is subjected to following working sequence until the weaving stage:
