  • Interface units for extrusion blow moulding control systems
    Patent number: 5665399
    Abstract: An extrusion blow mounding control system for controlling parison wall thickness in an extrusion blow moulding machine includes a wall thickness controller for controlling the width of an extrusion die gap defining parison wall thickness within the machine, an interface unit for supplying an input signal to the wall thickness controller dependent on an actual position signal from a position transducer indicative of the actual position of a movable die member delimiting the die gap, and an output for supplying a desired position signal from the wall thickness controller to an electrohydraulic servo valve for controlling the position of the movable die member to provide a desired width of the die gap.
