ABSTRACT:
A method and an apparatus are provided for blow-molding hollow articles. The blow-molding apparatus includes a carrousel mounted to rotate within a support frame. The carrousel carries four molds around a circular mold path. Two blow-molding work stations are disposed next to the mold path in fixed positions relative to the frame. The carrousel is indexed to cause each mold to pause by each work station one time during each carrousel revolution. The molds pause by each work station to allow blow-molding operations to be performed in conjunction with each mold at each work station. At one blow-molding work station, located at the 12:00 position of the mold path, an extruder injects parison into each mold. At the other work station, located in the 9:00 position of the mold path, a take-out mechanism extracts blow molded articles from the molds. The carrousel is additionally indexed, i.e., "double-indexed", to cause each mold to pause in the 10:30 position of the mold path where an in-mold labeling mechanism inserts a label into each mold.
