ABSTRACT:
In an extruder with a wide extrusion head and an associated calender, the wide extrusion head defining a sheet extrusion die 16 has an upper extrusion head, part 12 and a lower extrusion head part, which parts can be moved away from one another. At least one clamping device is provided which releasably presses the upper extrusion head part and the lower extrusion head part together and which is mounted in an associated side wall of the calender and is provided with a hydraulically operable piston cylinder drive. In order to achieve optimum clamping of the upper extrusion head part 12 and the lower extrusion head part, each clamping device has a tie rod which, on its one side bears against the lower extrusion head part or the upper extrusion part by means of a fixed abutment, e.g. a nut, or by means of an axially variable abutment e.g. a thrust box 51, which can be driven by a drive nut, the clamping device being mounted on the side wall to be freely movable in the upward and horizontal directions.
