Abstract: A method and apparatus for locating and withdrawing the free unwinding end of yarn from a bobbin randomly wound, rewinding a portion of the free end about the body of yarn with the remainder of the free end deposited on the bobbin for retention thereon until subsequent retrieval and withdrawal of the free end. Rewinding the end of yarn facilitates initial over end withdrawal of the yarn from the bobbin during subsequent unwinding, as at an automatic winding machine. The bobbin is telescoped onto and off of a horizontal spindle and is then dropped vertically through an adjacent chute. A spiraled suction tube effectively prevents fraying a long length of yarn drawn therethrough.

Abstract: High speed winding mechanism incorporating yarn engaging means operable to engage automatically the yarn to be wound on the mechanism, and including structure for delivering the yarn to the yarn engaging means from a locus remote from the winding mechanism. Control means are also included for regulating the movement of the yarn onto the winding zone of the winding mechanism after seizure of the yarn by the yarn engaging means. The mechanism may also include further control means for forming a transfer tail on the package of yarn to be wound.
