Abstract

A yarn end preparing assembly for a textile winding machine wherein yarn packages are disposed on peg tray-type tube support members and transported to winding stations along a common preliminary path to a respective one of a plurality of yarn end preparation devices which have components for sequentially handling the yarn packages to dispose their yarn ends in preferred preliminary dispositions. The yarn end preparation devices are each disposed on a respective branch path which branches the common preliminary path. The relationship of the branch path to one another can be varied and the relationship of each component of the yarn end preparation devices relative to the same respective component on the other yarn end preparation devices can be varied to optimize the production capability of the yarn end preparing assembly. Sensors and pivotable arm members are provided to selectively guide the tube support members to the branch paths.
