Device for removing the sliver end from the region of the opening cylinder of an open-end spinning unit

The invention relates to a device for the controlled removal of the end (44) of the sliver (41) from the range of the clothing (16) of the opening cylinder (15) after the fibre feed has been stopped in the event of a yarn break on an open-end spinning unit. According to the invention, a compressor (7) and a pressure shoe (9) are arranged on a supporting arm (6) which is mounted rotatably about an axle journal (5) of the feed cylinder (3) between a working position, in which the contact point of the pressure shoe (9) and of the feed cylinder (3) is nearer to the clothing (16) of the opening cylinder (15), and a position of rest, in which this contact point is further away from the clothing (16) of the opening cylinder (15). The supporting arm is preferably coupled to a force element (14) for pivoting into its position of rest, the force of said force element being lower than a moment, pivoting the supporting arm (6) into the working position, of the frictional force (43) between the feed cylinder (3), the end (44) of the sliver (41) and the pressure shoe (9). The limit positions of the supporting arm (6) are determined by adjustable stops (19, 20).
