Abstract:
1. An I.S. Machine including a blow station whereat a parison having a formed finish is transformed into a container within a blow mold including a pair of opposed side molds that are movable towards and away from each other, comprising an open and close mechanism for displacing the side molds from a remote location to a closed position, control means configured to operate when a parison is located at the blow station and configured to operate the open and close mechanism to displace the side molds from the remote location to a cracked position around the parison whereat a selected separation exists there between, and to maintain the side molds at the cracked position during reheating of the parison, said separation being controlled by the control means so that when a parison is located within the blow mold with the side molds located at the cracked position, the side molds will support the finish of the parison without neck ring holders while the parison reheats, and said control means further configured to subsequently operate the open and close mechanism to displace said side molds to the closed position at the conclusion of the parison reheating and then causing the parison to be blown into a container in the closed blow mold.
