Method for Operating a Workstation of a Spinning Machine or Winder

A method for operating a workstation of a spinning machine or winding machine, comprising:

• supplying an auxiliary thread from a thread nozzle to a suction assigned to the workstation, wherein the auxiliary thread is stretched between the thread nozzle and the suction;
• severing the auxiliary thread to form a thread section protruding into the suction and a thread section extending into the thread nozzle, wherein the thread section protruding into the suction is carried away by the suction;
• grasping the thread section extending into the thread nozzle with a thread receiver of the workstation, wherein the thread section extending into the thread nozzle extends between the thread nozzle and the thread receiver;
• severing the thread section extending into the thread nozzle to form a thread section remaining in the thread nozzle and a thread section coming from the thread receiver;
• transferring the thread section coming from the thread receiver to the suction of the workstation;
• and
• grasping the thread section coming from the thread receiver with a capture arrangement in an area of a tube made available by the workstation and starting a process of winding the thread section coming from the thread receiver onto the tube.

A thread nozzle for making an auxiliary thread available at a workstation of a spinning machine or winding machine, comprising:

• a first opening configured as an outlet or an inlet for the auxiliary thread;
• a second opening configured as an outlet or an inlet for the auxiliary thread;
• a compressed air inlet;
• and
• a valve configured to establish which of the first or second openings is an exit for compressing air from the thread nozzle thereby defining the outlet and the inlet for the auxiliary thread.
