ABSTRACT:
A winding station of a textile machine for producing cheeses is equipped with a device for pickup and transfer of a yarn from a cop to a splicer for joining to a yarn from a cheese, the pickup and transfer device comprising an air-blowing fitting, a pivot tube and a suction fitting connectable via a gripper tube to a suction source. The suction fitting is positioned outside of the normal yarn path and a yarn control device is arranged in front of the suction fitting in the area of the normal yarn path. A yarn end loosened from a spinning cop is pneumatically conveyed to the gripper tube and is threaded into the yarn control device by means of the pivoting of the gripper tube into an intermediate position and the simultaneous pivoting of the pivot tube into an operating position. If a yarn control signal is not present, no yarn splicing attempt is made and a fresh yarn pickup attempt is immediately started, i.e. the pivot tube and the gripper tube directly return into their yarn transfer or yarn pickup position.
