Device for winding-up a thread

摘要

A device for winding up a thread or yarn or the like into a yarn package on a rotatable, conical bobbin tube comprises a drive roller which has an intermediate rotational element fixedly coupled to a drive shaft and two lateral rotational elements disposed laterally of the fixedly coupled intermediate rotational element and rotatably supported on the drive shaft. The lateral rotational elements are interconnected by a differential transmission. The differential transmission comprises a friction coupling. This affords the advantage of a strong reduction in the danger of damage to the yarn package in the event of blockage of one of the lateral rotational elements. Furthermore, the results of faulty manipulation of the drive roller during servicing or maintenance thereof is very substantially reduced.
