Abstract
An apparatus for pneumatically aspirating a yarn end from a spinning cop (15) with a suction nozzle (33) whose working position is adjustable has a housing (16) defining a vertical aspirating slit (19) over which a sealing belt (31) is disposed. An air passage (32) is formed in the belt (31) with the suction nozzle (33) fastened on the belt (31) about the passage (32). The belt (31) is selectively displaceable between a sealing position completely closing the aspirating slit (19) in the housing (16) and various aspirating positions wherein the air passage (32) of the belt (31) is in communication with the aspirating slit (19) of the housing (16) to apply suction through the nozzle (33) to initiate an effective, yet gentle loosening of a yarn end (46) from the conical windings (43) or the surface area of a spinning cop (41).
