Abstract: An apparatus for trimming the neck of a blow molded plastic bottle in which a reverse punch is mounted on an end of a shaft. A knife is also mounted to the shaft adjacent to the reverse punch and includes a cutting edge recessed from the cutting edge of the reverse punch. A stripper arm is mounted on the shaft and axially moves with the shaft. The stripper arm's distal end is adjacent to the reverse punch and recessed from the cutting edge of the reverse punch. An actuator causes the distal end of the stripper arm to move to a position located radially outward from the cutting surface when a trimmer ring from the neck of a bottle is to be removed from the apparatus.

Abstract: Apparatus for blow molding plastic containers with a longitudinal view stripe of a transparent resin in the side wall for visually monitoring the level of the contents of the container. The apparatus includes a plurality of die heads each of which includes a mandrel sleeve having a diverter for directing the flow of a pigmented resin around the mandrel sleeve to form a tubular parison, and for inserting a longitudinal stripe of a clear resin into the pigmented resin. The container mold halves are positioned relative to the parison such that the view stripe is located on the parting line of the mold halves such that the length of the view stripe along the top and bottom walls of the container is controlled.

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.

Abstract: An accumulation head for a blow molding machine which produces a parison of a first melt material having a stripe of a second extruded plastic material formed by directing a second extruded plastic material into the stream of a first plastic material as the material in the accumulator is extruded to form the parison.
