ABSTRACT:
Apparatus for applying labels to spinning and translating containers has a rotating vacuum cylinder almost touching the containers. The printed sides of individual labels are deposited on the vacuum cylinder at which time fingers grip the leading end of the label to prevent the label from being attracted to an ensuing glue roller which has plural annular grooves and applies a strip of glue to the leading end of the label. The leading and trailing ends are also held by vacuum devices which are cam driven to extend by a small amount radially of the vacuum cylinder. The fingers register in the grooves of the roller so they do not interfere. The label on the cylinder is carried on the cylinder and secured at its trailing end by its own radially movable vacuum device. When the trailing end reaches a second glue roller the latter device moves radially outward of the cylinder to pick up a strip of glue on the trailing end. The label is then carried to a label application station where a blast of air from inside the holding device drives the leading end into tacky contact with a spinning container which causes the label to wrap around the container until the glue coated trailing end sticks to the container.
