Abstract
A method for enhancing the weaving of a warp yarn fabric having a high modulus of elasticity in which a sheet of parallel warp yarns is continuously unwound from a beam. The sheet is fed over a whip roll and a shed is formed using healds, the shed being defined in the forward direction of the warp by a shed opening point on an inlet side and a fell point on an opposite side. A weft yarn is inserted into the shed to form a resulting fabric which is evenly pulled and wound. The warp yarns are sufficiently heated in an area adjacent to the shed opening point to cause a local reduction in the modulus of elasticity of the warp yarns. Subsequently, the warp yarns are cooled in the shed before reaching the healds.
