Machine system for continuous formation of molecularly oriented plastic bottles by blowing a heat-conditioned parison comprising a set number (N) of parison forming stations and a set but lesser number (N/X) of blowing stations, N/X being an integral fraction of N. A storage area is constructed and arranged between the parison forming and blowing stations. In the method of operation, N number of parisons are formed simultaneously at the parison forming stations, transferred to the storage area, and N/X of the parisons are sequentially withdrawn from the storage area and blown in the set number N/X of blowing stations. The temperature in the storage area is maintained within the temperature range suitable for blowing. Effective use is made of the blowing stations without loss of thermal energy from the parison forming stations.
A machine system for manufacture of molecularly oriented plastic bottles comprising a plurality of parison forming stations for simultaneous formation of a plurality of parisons equal in number to the number of parison forming stations, a storage area for temporary storage of said plurality of parisons constructed and arranged to maintain said parisons in said storage area at substantially the blowing temperature of said parisons, means for simultaneously transferring said plurality of parisons from said parison forming stations to said storage area, a plurality of blowing stations for blowing parisons wherein the plurality of blowing stations is less than the plurality of parison forming stations, and means for sequentially and simultaneously transferring a plurality of parisons equal to said plurality of blowing stations from said storage area to said blowing stations.
