Abstract
A thread supply device, as for a textile machine, having a stationary thread drum onto which a thread which comes from a storage bobbin can be wound tangentially by means of a winding-on member which rotates around the drum edge for forming an intermediate thread supply on the drum. The thread can be pulled off the drum through a central withdrawal eye. A thread control element is arranged in the area of the withdrawal path of the thread. The thread control element has the form of a hook and is secured on the winding-on member. The hook receives the withdrawal thread in its mouth to limit the thread withdrawal speed to the thread winding-on speed. In the thread withdrawal path, downstream of the hook, there is provided a cut-off eye arranged on a swivel arm which can be swung transversely to the thread path from an operating position into a nonuse or shut-off position. This arm is hinged to the rotating winding-on member and swivels about an axis which is substantially aligned with the axis of the drum.
