ABSTRACT:
A method and apparatus are provided for multiple simultaneous blow molding operations for forming hollow objects such as containers, the method and apparatus employing at least two circumferentially spaced parison forming means with a single rotary indexing turntable. A first container is formed at one station and a second container is formed at about the same time at a second station circumferentially spaced from the first station, and the containers are simultaneously circumferentially transferred to an unloading station. The method and apparatus provide for multiple container forming and unloading operations on the same turntable. Different containers may be manufactured at the same time with one rotary indexing turntable.
