IN-MOLD LABELING APPARATUS AND METHOD

摘要

An in-mold labeling apparatus includes a label transfer assembly carrying a number of label carriages each with a number of label transfer heads. A continuously rotating drive arm raises and lowers the assembly in simple harmonic motion to move the label transfer heads between label magazines for pickup of labels and mold halves of a blow molding machine. Lost motion connections are provided at the top and bottom of the stroke to facilitate pickup of labels and placement of labels in the mold halves.
