ABSTRACT:
An invert and neck ring holder mechanism for displacing a parison from a blank station to a blow station. The invert and neck ring holder mechanism has an opposed pair of side brackets, a worm gear housing supporting a worm gear, and a motor/worm housing for supporting the worm gear housing intermediate the opposed side brackets. The invert and neck ring holder mechanism also has a pair of cylinder assemblies extending between the sides of the worm gear and the side brackets. The cylinder assemblies include a cylinder having an in support. Each cylinder is axially displaceable from a first location adjacent the worm gear to a second location adjacent the associated side bracket and rotationally displaceable to displace its neck ring holder support from a first position at the blank station to a second position at the blow station. A first switch indicates that said first cylinder assembly cylinder is proximate its associated side bracket, a second switch indicates that the first cylinder assembly neck ring holder support is at the first position, a third switch indicates that the second cylinder assembly cylinder is proximate its associated side bracket, and a fourth switch indicates that the second cylinder assembly neck ring holder support is at the second position.
