  • Apparatus for the manufacture of tubular preforms of plastics
    Patent number: 4652229
    Abstract: The invention relates to a method for the manufacture of tubular preforms. Its purpose is to improve the flow pattern in the plastics chamber and simultaneously to shorten the dwell time of the plastics. This is achieved, in the course of the dip blow method, by the fact that the geometric form of a plastics chamber (that is distinct from a separate screw chamber) is changed and the volume is decreased so that the tubular preform acquires a certain thickness or thickness distribution.
    Type: Grant

  • Molding device
    Patent number: 4260358
    Abstract: A molding device for the manufacture of hollow plastic articles comprising of a two part separable mold, a pre-cast station, a blow station, means for moving the mold halves between the closed and open positions, and means for moving the mold between the preform station and blow station. The mold is supported for movement between the open and closed position by a single supporting spar and locking means are employed for locking the mold parts in the closed position.
