  • Apparatus for controlling the gap between lips of a die for extruding a plastic sheet material
    Patent number: 4124342
    Abstract: An apparatus for adjusting the gap between lips of a die for extruding a plastic sheet material. A pair of flat plates spaced from each other have a plurality of bolts for controlling the gap. The operational adjustment of each bolt is generated as an electric signal, and this electric signal is added with reference to all the bolts to distribute the gaps between the die lips. Each adjustment is changed so that the distribution of the gap between the die lips acquires a predetermined form to thereby determine the necessary amount of adjustment of each bolt.
