Abstract:
A method for improving the weaving of a fabric of warp yarns having a high modulus of elasticity, said method including the steps of:unwinding a layer of parallel warp yarns continuously from a beam;processing said layer over a back-rest roller;forming a shed by means of healds, said shed being defined, in the direction of advance of the warp, by a shed opening point at the entrance thereof and by a fell point on an opposite side;inserting a weft yarn into the shed in the vicinity of the fell point in order to form a fabric;heating the warp yarns in the vicinity of the opening point of the shed to a temperature sufficient to cause a local reduction in the modulus of elasticity of said warp yarns;cooling said warp yarns in the shed following said heating step before said yarns reach the healds; andpulling and winding the formed fabric uniformly.
