Beschreibung
Zusammenfassung:	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at the parison forming stations, transferred to the storage area, and N/X of the parisons are sequentially withdrawn from the storage area and blown in the set number N/X of blowing stations.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.
