Abstract
A system for applying pressure sensitive labels to articles, such as bottles, includes a vacuum drum having an outer cylindrical surface, a plurality of vacuum passages in open communication with the outer surface and equally spaced around the drum, means for delivering pressure sensitive labels onto the outer surface of the drum at a predetermined speed of advance and means for rotating the drum with a predetermined linear speed of the outer surface which is greater than the speed at which labels are delivered to the outer surface, so that the outer surface slips on each label until vacuum is applied to a vacuum passage at a label pick-up station, whereby the vacuum picks up the front edge of each label, and whereby labels are spaced uniformly on the drum from the label pick-up station to a label applying station.
