Abstract
An I.S. machine is disclosed which has at least one section having a mold station wherein a glass forming operation is performed within a mold which includes an opposed pair of mold halves each of which has a blank diameter which can vary within a selected range and a planar surface to be clampingly engaged with the planar surface of the other mold half at a mold centerline. The section has a mold open and closed mechanism which includes a pair of opposed displaceable mold holders for holding one or a plurality of opposed pairs of mold halves, and a drive assembly for displacing the mold holders from a selected open position, the location of which is a direct function of the dimension of the blank diameter of the mold halves supported on the mold holders, to a closed position.

An I.S. machine including at least one section having a mold station wherein a glass forming operation is performed within a mold including an opposed pair of mold halves each of which has a blank diameter which can vary within a selected range and a planar surface to be clampingly engaged with the planar surface of the other mold half at a mold closed position comprising
- a pair of opposed mold holders for holding at least one opposed pair of mold halves, the opposed mold holders being displaceable towards and away from the mold centerline,
- drive assembly means for displacing said mold holders a predetermined distance from an open position to the mold closed position, the predetermined distance being a direct function of the dimension of the blank diameter of the mold halves supported on the mold holders.
