ABSTRACT:
An invert and neck ring holder mechanism having an opposed pair of neck ring holders displaceable from a blow station to a blank station of a section of an I.S. machine. The invert and neck ring holder mechanism has a pair of an opposed pair of pneumatically operated cylinder assemblies extending between a gear housing a gear and side brackets including a cylinder housing supporting a neck ring holder support rotatable with the gear and axially displaceable from an open position to a closed position. Each of the cylinder housings includes a target sensed by a sensor when the neck ring holder support is at the closed position. Each of the targets is configured so as to be sensed by the associated sensor for a selected angular range when the neck ring holder support is at the closed position. The angle of displacement of the neck ring holder supports when the sensors sense the associated target are determined so that the condition of the pneumatic cylinder can be evaluated and so that offsets can be defined for variations between actual and programmed angles for event occurrences.
