Abstract
The present invention provides a blow molding apparatus which conveys preforms to a blow molding stage while holding the preform by two rows of supporting plates, places the preforms in two rows of blowing molds disposed corresponding to the supporting plates, blow molding the preform into hollow containers when the blowing molds are in their closed positions, thereafter opening the blowing molds to remove the molded containers therefrom. In this blow molding apparatus the row pitch between the supporting plates is changed between one when the blowing molds are opened and another when the blowing molds are in the other conditions. In this apparatus, the row pitch between the supporting plates is not required to maintain the maximum pitch when the blowing molds are opened. Thus, the blow molding system may be reduced in size and occupying area.
