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., six (6); and a storage area between the parison-forming and parison-blowing stations, improvements are described in the mechanisms for transferring hot parisons from the storage area to the blowing stations on a continuous basis.
Claims7
In a machine system for manufacturing plastic bottles comprising a plurality of parison-forming stations, a plurality of blowing stations fewer in number than the number of parison-forming stations, a storage station for holding parisons formed at said parison-forming stations, and means for transferring parisons from said parison-forming stations to said storage station and from said storage station to said blowing stations;
- the improvement wherein the storage station includes support means for receiving a plurality of parisons X from said parison-forming stations, and the transfer means from said storage station to said blowing stations include shuttle means for sequentially transferring from said support means a plurality of parisons Y, which plurality is fewer in number than said plurality of parisons X to a station intermediate of said support means and said blowing stations, and conveyor means for simultaneously receiving said plurality of parisons Y from said intermediate station and continuously transferring said plurality of parisons Y individually and sequentially from said intermediate station to said blowing stations.
