Transfer tail apparatus and method for vertical spindle winder

Abstract

The transfer tail apparatus of this invention comprises a tail forming string-up aid, a tail cutter, and tail storage mechanism. The method is to form the tail as the yarn is traveling from a supply source around a spool of the spring-loaded string-up aid to an aspirator which has an internal tail cutter. After the winder has started, and the rotating bobbin flange, which has a pin attached underneath and near the outer edge, reaches the desired speed, the spring-loaded string-up aid is manually released. The string-up aid springs upward to bring the yarn being aspirated to a position where the rotating bobbin pin engages the yarn. At this point, the yarn in the aspirator is reversed in direction and tension is applied to the yarn across the internal cutter which cuts the yarn. The string-up aid and tail cutter are located so that when the yarn has been cut and the direction is reversed, the yarn is directed into a tail storage slot underneath the bobbin flange. When the bobbin is removed, the slot no longer exists and the tail may be easily used. This apparatus and method allow formation of the tail of the inside end of the yarn which is preserved undamaged and extends from the inside of the full package to allow a junction between the tail and the head of another package to be processed.
