Abstract
A device for the peripheral drive of the yarn-takeup package of a double twisting machine, i.e. a so-called DD twister, comprises a coupling sleeve freely rotatable and axially shiftable on a drive shaft, the coupling sleeve being angularly entrained with the axially fixed winding cylinder and connectible with a hub angularly entrained with the drive shaft. The coupling sleeve is shifted in response to the position of a thread-sensing element from its coupled state into a free-running condition.
