Abstract
1,101,852. Extrusion machines. POLYSIUS S.A.R.L. 12 Feb., 1965 [17 Feb., 1964], No. 6102/65. Heading B5A. Plastic material, e.g. cement paste, is extruded through apertures 2 in the bottom of a trough 1 by members comprising curved plates 5, 6 mated at 7 in a pointed leading edge and joined at their trailing edges by a plate 8 which supports an adjustable knife 13. A trough 1<SP>1</SP> may be connected to trough 1. Two pairs of members may be disposed in tandem, one pair being offset 90 degrees with respect to the other pair, Figs. 2 and 3 (not shown). Generally plate 6 has a radius of curvature less than that of trough 1, but if equal curvatures are employed the members may be positioned off-centre as at I. Preferably shoe plates 6 have smooth outer surfaces and inner surface 10 of trough 1 is roughened.
