This relates to a blow molding apparatus wherein in lieu of the mold halves closing on a preform and thereafter the blowing operation initiated, the preform is shifted into one of the mold halves and thereafter advance of the stretch rod into the preform and movement of the blow head to a position closely adjacent the preform is effected before the closing of the mold is completed. Such arrangement permits a reduction in cycle time. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
