<p>Docket M-275-C APPARATUS FOR PRINTING AND APPLYING PRESSURE SENSITIVE LABELS It is a feature of the invention to provide a label printing and applying apparatus having a brake member for applying a braking force to a composite web upstream of a printing zone, a feed roll which cooperates with a supporting material web of the composite web and a feed wheel for advancing the composite web, and an edge guide for guiding the composite web at its one side edge. The brake member, the feed roll, and the edge guide are operable by a deactivating and activating mechanism. This mechanism enables the brake member, the feed roll, and the edge guide, which are normally in their effective positions throughout the operating cycle of the apparatus, to be moved to their respective ineffective positions. Thus, there is no interference with the threading of the composite web through the apparatus. When the mechanism is operated, the brake member, the feed roll and the guide are simultaneously moved to their ineffective positions. The mechanism includes an overcenter arrangement for releasably holding the brake member, the feed roll, the guide in either their effective or their ineffective positions until the mechanism is operated.</p> |
