ABSTRACT:
A device for the uniform retrieval of yarn ends in an air spinning device. A suction force gradient is created between the air jet nozzle and the waste suction pipe. Gravitational force and the suction gradient cause broken yarn ends to drop from the air jet nozzle orifice toward the waste suction pipe. When yarn piecing is desired, a piecing suction pipe retrieves the yarn end from the nozzle orifice.
