Abstract
A frictional false twisting unit including a plurality of driven shafts, a driven pulley on one of the shafts, an externally arranged motor with a drive shaft, an endless loop toothed belt between the drive shaft and the driven pulley. The shafts are on a carriage or base plate which is moveable or swingable with respect to either the motor or a base plate on which the motor is disposed. The shaft carrying base plate or carriage is movable to slacken the toothed belt, enabling removal of the driven pulley from the toothed belt and removal of the shafts from the unit. The thread monitoring devices of the unit remain with the unit while the shafts are removed. Channels for the lateral runs of the toothed belt prevent excessive spread of the belt when it is slack and when the driven pulley is removed. A guide beneath the belt prevents the belt from moving down axially when the belt is slack and the driven pulley is removed.
