Abstract
In a thread winder comprising first and second chucks and a friction drive member selectively engageable by the chucks, there is provided a screening plate movable from a retracted position into an operative screening position between an idle position of the first chuck and the winding position of the second chuck which prevents thread tails dangling from a completed package on the first chuck from engaging and becoming entangled with the package forming upon the second, usually lower, chuck or the friction drive member. An auxiliary guide or deflector is provided for deflecting a thread during changeover of winding from the first, usually upper, chuck to the second, usually lower chuck. This auxiliary guide or deflector also cooperates with the screening plate to screen a package on the first chuck from a winding operation on the second chuck. A control system controls the retraction and advancement of the screening plate in response to operation of the winding machine.
