Abstract

A molding apparatus has an injection section for injecting material for forming parisons. A blowing section (39) is opposite the injection section (37) for expanding parisons, the blowing section shiftable in a first direction toward and away from the injection section between a compressed/contracted condition of the molding apparatus and an expanded/extended condition of the molding apparatus. A transfer section (38) between the injection section and the blowing section is rotatable by 180° about a second axis transverse to the first direction between a first condition and a second condition. The transfer section has a first side and a second side. Each side has a plurality of core members received in injection cavities and blow cavities during injection and blowing. In the first condition, the first side faces the injection section and the second side faces the blowing section. In the second condition, the first side faces the blowing section and the second side faces the injection section.
