Abstract
Line for extruding a continuous web 6 of thermoplastic cellular-structure plastic material in corrugated form, comprising a loader 1, an extruder 2, a filtration means 3 for filtering out any impurities present in the extruder 2, an extrusion head 4, a gear pump which produces a constant flow rate of material at the extrusion head 4, a calibrator 5 and a draw device 7 for drawing the continuous web 6. The line is characterized in that it has means for producing a relative oscillating motion between the extrusion head 4 and the calibrator 5. The effect i.e. of this is to produce a web 6 in a corrugated form that is stronger than a flat web as regards loads distributed on an axis parallel to the cells. (Fig. 1a) <IMAGE>
