Abstract

A disc for simultaneous SZ false twisting arranged with a a ring shaped elastic member forming a first friction surface and second friction surface on either side of the outer periphery of the disc and which imparts a false twist in opposite directions in a pair of yarns at each of the first friction surface and second friction surface, wherein each of the first friction surface and second friction surface of the elastic member are convex shaped.
