ABSTRACT:
Blow molding apparatus for producing an article including compression rings or other compression molded areas utilizes mold halves each having multiple mold sections connected in end-to-end relation by a series of guide rods having end stops to permit limited movement of the mold sections toward and away from one another. With the present control rod arrangement, only a single actuating arrangement is necessary to accomplish the formation of multiple compression molded areas.
