Friction false twisting device - for texturising thermoplastic yarns, has a guide for holding a moving yarn at an angle to the direction of motion of a moving belt

Abstract

Abstract The device comprises (a) an endless belt supported by two rollers rotatable round their axes and mounted on a carrier which can pivot round an axis perpendicular to that of the rollers, and (b) means for driving one of the rollers supporting the belt and guide elements for guiding the yarn over one of the belt sections at an angle to the direction of motion of the belt such that the angular position of the belt is automatically adjusted during operation of the appts. in such a way that the helical pitch line of the twisted yarn is parallel to the direction of motion of the belt. This enables a textile yarn to be textured by frictional false twisting while ensuring a stable course for the yarn and a constant rotational density (i.e. turns per unit length).
