Abstract: An apparatus and a method for handling the unwinding end of a wound body of yarn by releasing the end from adjacent winds of the yarn and, with the bobbin rotating, picking up and carrying the released end in a stream of air flowing into a suction nozzle. Lips of the suction nozzle automatically conform to the configuration of the body of yarn. One of the lips may engage the body to aid in releasing the end from the body and providing an air seal, and the other lip may be spaced from the body, thus providing more effective flow of the stream across the body to pick up the unwinding end. If desired, both lips may be spaced from the body of yarn. The unwinding end from the body of yarn, and a nozzle, as described above, if desired, may be provided for withdrawing the unwinding end.
