ABSTRACT:
A yarn false twisting apparatus which comprises a drive motor and a yarn false twist assembly, both mounted on a base frame. The yarn false twist assembly comprises a plurality of spindles mounting friction disks which are rotated in the same direction by the motor, and the assembly is releasably mounted to the base frame so it can be separated from the base frame by withdrawing the assembly in an axial direction. The drive motor has a drive pulley, and at least one of the spindles has a belt pulley, which can be interconnected via a drive belt. The drive belt is arranged in a drawer-like housing, which is displaceable in the operating plane of the drive belt. At its free end, the belt pulley mounts a cone, which ensures that the drive belt slides onto the belt pulley when mounting the false twist assembly to the base frame.
