Abstract
The mechanism comprises a pressure sensitive label dispenser for delivering successively pressure sensitive labels from a backing sheet to a label applying station. At the applying station is a mouthpiece having one longitudinal side edge arranged to be transversely disposed across the path of feed of the backing strip and having a lower perforated label carrying surface of less width than the label to be carried thereby. Mounted on the other longitudinal side edge of the mouthpiece is an applying roll. The mouthpiece forms a part of a unit which is fastened to the label dispenser so that a label discharged therefrom moves across the label carrying surface and comes to rest with its advancing edge portion positioned beneath the applying roll. A tubular shaft which also communicates with the mouthpiece to provide suction at its label carrying surface supports the mouthpiece for pivotal movement about its one longitudinal side edge. The shaft has affixed thereto a straight lever, to one arm of which, is connected a solenoid which is energized by electronic means actuated by register marks on a rapidly moving web or by objects carried by a rapidly moving conveyor to pivot the mouthpie…
