Abstract
In a machine system for continuous formation of molecularly oriented plastic bottles by blowing heat-conditioned parisons comprising a plurality of parison-forming stations, i.e., sixteen (16); a plurality of blowing stations, but fewer in number than the number of parison-forming stations, i.e., four (4); and a storage area between the parison-forming and parison-blowing stations, improvements are described primarily in the storage area and in the mechanisms for transferring hot parisons from the parison-forming station to the storage area and from the storage area, sequentially in multiples, to the blowing station.
Claims7
A device for simultaneously receiving and transferring a plurality of hot parisons comprising in combination support means;
- carriage means movably mounted on said support means;
- means for reciprocally moving said carriage means laterally to said support means;
- arm means mounted on said carriage means for lateral movement with said carriage means;
- a plurality of parison gripper means mounted on said arm means, each of said plurality of gripper means having a jaw set;
- actuating means for said jaw sets including a pair of actuating members, one jaw of each of said jaw sets mounted on one of a pair of said actuating members and the other jaw of said jaw sets mounted on the other of said pair of actuating members constructed and arranged with said arm means and actuating means, said actuating means for actuation of said actuating members being constructed and arranged with said actuating members to simultaneously open or close said jaw sets upon actuation of said actuating members.
