Abstract
This relates to a web pay-out assembly wherein a web in spool form is mounted on a hub for selective paying out of the web. The hub is of a hollow construction and includes an internal chamber. A plurality of radiating pins project into the chamber and are projectable radially outwardly beyond the hub for engaging a tubular core of the spool to lock the spool in place on the hub. The pins are resiliently urged inwardly and are cammed outwardly by a nut member threaded onto a positioning member. The hub has opposite flanges and one of the flanges has a tubular extension which is mounted on a control shaft of a control unit. The control unit supports the hub and is mounted on a combined partition and support wall of a machine. The control unit has a mounting flange which is mounted in sealed relation with respect to a tubular spacer and the control unit passes through an opening in the wall so as to be primarily disposed on the opposite side of the wall. Two of the hubs may be mounted in adjacent out-of-aligned relation by providing spacers of different lengths so as to space the hubs differently from the wall.
