ABSTRACT:
A vertical injection-molding machine with two overlappingly operating injection molds produces two sets of eight parisons each in staggered operating cycles. Each set of parisons is transferred by a respective carrier assembly, immediately upon the opening of the respective injection mold, into the vicinity of a blow-molding unit with eight cells in which the parisons are inflated into bottles during half an injection cycle. The transfer from the closely spaced injection cavities to the blow-molding unit is performed by several carriers moving over laterally diverging tracks whereby the parisons arrive at the blow-molding unit in pockets of these carriers already separated to the extent necessary for joint introduction into the eight-cell blow mold.
