Abstract: Apparatus for feeding plastic label stock, regardless of curling, to a label-wrapping station is disclosed. The apparatus and method include a first label guide means including a turning bar that directs the plastic label sheet from a supply roll towards a rotary vacuum drum in the label-wrapping station, knife means for cutting the label sheet into desired lengths to form labels, secondary guide means for guiding the label to the vacuum drum periphery, and final guide means to positively turn the label back into the drum periphery, especially during start-up, and regardless of curl.

Abstract: Apparatus and methods are disclosed for a high speed production line in which a container is wrapped with a plastic label comprising a foam polystyrene layer, there being means to move a leading edge of the label to the periphery of a rotating vacuum drum, means to apply methylene chloride to the underside of the foam layer to form finite areas on the leading label edge and a finite area on the trailing edge. The finite areas have therein a rapidly solidifying tacky solution of the foam polymer in methylene chloride, the tacky viscous solutions rapidly solidifying to form an adhesive bond. The solvent-applied label is quickly moved to a label wrapping station where it is wrapped around a container, the finite areas on the leading edge tacking the label to the container, and the finite area on the trailing edge forming a cohesive bond on the seam formed by the overlapped label ends.
