ABSTRACT:
A rotary vacuum wicketting arrangement has a rotary hub body positioned on a shaft or spindle and supporting a number of pickup arms, and a non-rotating vacuum spinning head that provides vacuum to the rotating hub body and pickup arms over a portion of their arcuate travel. The rotary hub body is provided with a lock ring formed or a pair of half rings with hand levers so that the position of the hub body on the shaft can be adjusted toollessly. The pickup arms are held in place in their sockets by ball and spring detents, so that they can be pulled out for cleaning and reinserted without tools. A friction fitted plug closes off the end of each arm.
