Abstract

The invention relates to an adjusting device for the annular gap at the output end of a multiple part annular die of a continuous web extruder 1 intended for the manufacture of a cellular plastic web material, which extruder comprises an inner die part 3 and an outer die part 4, between which the annular gap 20 is formed and from which gap a tubular extruded material 9 formed from foam plastic is delivered, which is led over a cooling mandrel 10, cut up by a cutter device 12 and straightened out. The adjusting device comprises a connection 5 releasing the end situated in the delivery direction of the outer die part 4, which connection through the internal path via the hose-shaped extruded material 9 and through the cooling mandrel 10 and the hydraulic medium pressure hose 11 carried via the tube cutting point determined by the rotary cutting device 12 is connected, hydraulically adjustable, to a hydraulic pump 15. <IMAGE>
