Abstract
An injection blow molding system includes an injection molding station (22), a first delivery section (24), a cooling station (26), a heating station (30), a second delivery section (32) and a plurality of blow molding stations (34). The station (22) simultaneously injection molds M rows of N preforms (36) arranged in a second direction (B) perpendicular to a first direction (A) in which the preforms (36) are carried. The first delivery section (24) removes the M rows of preforms (36) using a removing mechanism (102) in their upright state while decreasing the pitch in the rows. The preforms 36 are inverted with the column pitch changed by an inverting mechanism (104) before delivery to the cooling station in their inverted state. The cooling and heating stations (26), (30) cool and heat one row of N preforms (36) while parallel carrying them along a first carrying chain (200). The second delivery section (32) delivers the preforms (36) to two blow molding stations while in their inverted state. Each blow molding station (34) stretch blow molds the N/2 preforms into containers at the same time.
