ABSTRACT:
Apparatus for applying labels in the molds of a plastic blow molding machine of the type wherein a plurality of sets of molds are mounted on a wheel rotatable about a horizontal axis. Mold sections are moved toward and away from one another to enclose a parison, and the parison is then blown to the confines of the cavity between the mold sections. The apparatus removes labels successively from one or more magazines, and deposits labels on an endless conveyor that transports the labels to a position adjacent an open mold. The apparatus laterally transfers the labels successively from the conveyor to a position within the mold section, such that when a mold closes about a plastic parison and the parison is blown, the labels become adhered to the blown plastic article. The label magazines are mounted in horizontal orientation, and the label pickup mechanisms are moved by a positive-action slider crank in a straight line for picking up and removing a label from the magazine, and in a straight line for delivering the label to the conveyor while the conveyor is stationary. The label placement apparatus is positively driven to remove the label from the conveyor while it is stationary and deliver it to the mold cavity.
