Abstract
An apparatus and method for high speed placement of labels onto containers by a continuous motion. The label stock is transferred to a rotary vacuum drum, carried by rotation of the vacuum drum to a glue application station and then to a label application station where the glue coated labels are wrapped onto containers. As the containers reach the labeling position they are already rotating so that their surfaces are moving at the same speed as the drum surface. The labeled containers are then discharged onto a conveyor where they are held against rotation and stabilized by a pair of parallel belt drives. Glue is imprinted onto each label by a roller with a patterned surface. The roller picks up glue as it rotates past a glue bar surface which emits glue from a tapered exit. The tapered configuration causes build up of suitable pressure so as to force the glue into the pattern on the glue roller. A downstream edge of the glue bar surface acts as a doctor to spread and wipe off excess glue. The excess glue collects in a hollow adjacent to the edge, and may be recirculated.
