Abstract
Abstract A textile thread-winding apparatus has a turret with two spindles each adapted to receive a thread carrier. The turret can turn to bring either of the spindles into the winding on station, and in so doing, it pushes a deflector into the path of the thread. The deflector guides the thread onto a catcher on the spindle at the winding on station, so that the latter begins to pick up the thread. The full package continues to rotate even at the reserve station until the trailing thread to the catcher is severed.
