Abstract
A method is provided for manufacturing a bias fabric provided with characteristic physical properties by continuously varying the intersecting angle between the warp and the weft by a mechanical device. A fabric subjected to the process according to the invention can be any type of fabric woven on conventional looms such as satin, twill, plain and duplex fabrics. The principal part of the apparatus according to the invention is comprised of a fabric supplying device, a resin impregnating device to apply resin to a fabric for the purpose of fixing the bias structure produced by deforming the orthogonal structure of the original fabric, a heat setting oven to heat set the resin impregnated fabric, a pair of endless tenter chains provided with needle blocks to hold the fabric at the selvages, each of the endless tenter chains comprising an arched part whereby the intersecting angle between the warp and the weft is varied while the weft is maintained in the direction parallel with the original direction thus forming a bias structure, a device to release the fabric from the needle blocks and a take-up device to wind the bias fabric in a roll.
