Abstract of the Disclosure A rotary blow molding machine includes a base, a turntable on the base rotatable about a vertical axis and a number of mold units spaced around the turntable. Each mold unit includes a pair of mold halves which close on and capture a growing vertical parison at an extrusion station and then fall away from the parison as the parison is severed. The captured parison is blow molded and cooled as the blow unit is rotated around the turntable. The finished article, commonly a bottle, is ejected from between the mold halves before the mold halves return to the extrusion station.
