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.

A yarn splicing device for textile winding machines comprises a splicer mechanism for pneumatically joining yarn ends, upper and lower clamping and cutting devices, and suction-actuated yarn placement devices for placing the yarn ends to be spliced. According to the invention, one yarn placement device is a gripper tube normally parked in a zero position upstream of the yarn travel. The gripper tube has a spring-biased, pivotable gripping flap and a yarn placement hook for simultaneously placing both the lower yarn and the upper yarn to be spliced. For that purpose, one of the gripper tube and gripper tube flap carries the yarn placement hook forwardly for manipulating the upper yarn and a yarn guide disposed between the yarn placement hook and the pivot axis of the flap for placing the lower yarn.
