Abstract
A false twister for S or Z false twisting in which the false twist-imparting members, e.g., disks, and their shafts are rotatably driven about a fixed axis of rotation by alternately selectable drives in turn driven by tangential contact between an endless drive belt and a pair of whorls, the whorl assembly being swingably mounted on the twister assembly to provide drive contact and counterpressure contact by respective whorls.
Claims11
A false twister comprising a false twister unit including rotating means for applying a false twist to threads running therethrough, a whorl having a vertical axis of rotation, an endless drive belt adapted to drive said whorl when the latter is in tangential contact with said belt, and characterized by said whorl being rotatably journalled on a swinging member pivotally mounted on a vertical shaft and adapted to pivot about a vertical axis, thereby shifting said whorl into and out of tangential contact with said belt, said rotating means having fixed, constant axes of rotation providing the same path for the thread running therethrough in both S-twist and Z-twist, and rotational drive connection means operatively connecting said whorl and said rotating means.
