Innovation in weaving–Vertical bi-phase weaving machine for individual warp thread control

Abstract

Prototype of a new weaving machine to replace existing jacquard weaving machine has been developed for increasing the width of the design repeat and doubling productivity. This development also eliminates the constraint of change in warp sett in jacquard weaving machines. Change in warp sett can be made conveniently in this new development. There is only change in the shedding system; one such unit is common to two weaving machines. The weaving machine produces simultaneously two fabrics, one face up and the other face down. The warp yarn does not move unless a change from up to down is required. The warp sheet is in a vertical configuration instead of the usual horizontal plane.
