ABSTRACT:
An in-mold labeling device for blow molding machines which includes a carriage assembly which moves a labeling head between a position in registry with a label storage magazine to a displaced position in registry with a cavities of molds. The labeling head includes a pick-up arm which is pivotable and supports a self aligning pick-up pad which carries one or more vacuum cups. In operation, the carriage assembly moves to a first position where the pick-up arm is pivoted to place the vacuum cups in contact with a label carried by the storage magazine. The pick-up arm is then pivoted back to pull off a label, and a slide is moved to position the labeling head into registering with an open mold. The pick-up arm is again pivoted to deposit the label in position onto the inside surface of the mold cavity and is maintained in that position through vacuum ports within the mold. Vacuum signals to the vacuum cups are relieved and the pick-up arm and the slide member are returned to their initial position to engage another label.
