APPARATUS FOR APPLYING LABELS TO CONTAINERS

摘要

A labeling machine wherein a label transport drum (12) carries one or more pairs of vacuum pads (16) to grip the leading and trailing edges of a label. A knife (24) carried directly on the drum acts with a stationary blade (26) to sever each label from a continuous web. The vacuum pads are retracted as they pass the stationary blade, but when they carry a label past a glue roller (34), the vacuum pads are extended to press the label against the roller. If desired, two glue rollers may be employed, with different glues being applied to the leading and trailing edges of each label. In that case, one pad is retracted and the other extended to each glue roller.
