Abstract:
An I.S. machine including at least one section having a blank station and a blow station comprisinga section frame having a top wall, an invert and neck ring mechanism supported on the top wall of said section frame and including a pair of opposed neck ring holder arms, a cylinder for supporting said opposed pair of neck ring holder arms for displacement from a closed position to an open position, a support structure mounted on said section frame for supporting said cylinder for rotation between a first orientation whereat said pair of neck ring holder arms are horizontally located at the blank station to a second orientation whereat said pair of neck ring holder arms are horizontally located at the blow station, drive means for rotating said cylinder from said first orientation towards said second orientation to a selected orientation establishing a selected angle between said selected orientation and said second orientation, and displacement means for displacing said neck ring holder arms to the open position, said section frame including a downwardly extending cullet chute having a top opening defined in said top wall, said top opening extending from a location beneath said pivotally mounted cylinder towards said blow station, a mold open and close mechanism supported on said section frame including an opposed pair of blow mold support mechanisms and displacement means including a motor operable to displace said opposed pair of mold support mechanisms between open and closed positions, and control means comprising means for operating in a preheat blank molds mode including means for maintaining the blow molds at the open position, means for cyclically operating said drive means to rotate said cylinder to displace sequentially formed parisons to said selected orientation, and means for operating said displacement means to displace said neck ring holder arms from the closed position to the open position when said cylinder has been rotated to locate a parison at the selected orientation.
