摘要：Apparatus and method of applying wrap-around labels to bottles or containers where the label is formed into a complete sleeve with a heat-sealed seam on the container as the containers are moved in a linear path on a conveyor. The bottles and conveyor pass between a continuously moving set of rectractable, electrical heat-seal bars and vacuum label handling heads. The vacuum heads receive individual labels which carry the labels into position opposite a bottle on the conveyor. Vacuum fingers that grip the ends of the label are moved outward on arcuate arms that are pivoted to the head to move the labels about the containers in overlapping relationship. The opposed heat-seal bar is advanced into contact with the overlapped edges of the label and held there for a time sufficient to complete the full height heat seal of the label. The heat bar is contoured to the same shape as the external profile of the container over the label height.
