ABSTRACT:
In the extrusion of thermoplastic deformable plastics, especially the manufacture of plastic plates, an automatic regulation apparatus on the roller discharge ensures that the extruded plastic plate is directed horizontally along the device center after leaving the roller calender. The apparatus contains a sensor unit which transmits a position signal for the horizontal position of the plastic plate to a controller which, when a deviation of the plastic plate center from the device center occurs, activates two pneumatic plug cylinders such that the plug force of the haul-off rolls changes the roller diameter and thereby guide the conveyed direction of the plastic plate.
