Abstract

1,225,515. Working plastic materials. H. LEU AND H. KOCHER. 17 April, 1968 [17 April, 1967], No. 18175/68. Heading B1C. Apparatus for working plastic materials comprises a barrel 1 having a rotor 2 comprising a divergent portion 5 to induce turbulence, a cylindrical portion 6, a further divergent portion 7 to stabilise flow, a further cylindrical portion 8 and a convergent portion 10. The barrel may be surrounded by annular chambers 18-22 through which a heat transfer medium may be circulated, and it may be lined with a quartz-glass sleeve 26 and provided with a roughened surface 29 in the zones shown. The rotor may be provided with a screw 4, or truncated cone, to feed material through the barrel. Turbulence may be induced by providing diverging portion 5 with a profile having a change of curvature at one point, Fig. 3 (not shown), and stability of flow may be introduced by providing diverging portion 7 with a profile of exponenential shape, Fig. 4 (not shown). The convergent portion 10 of the rotor may be provided with an axial groove, Figs. 5, 6 (not shown). A high frequency generator 25 may be connected to the barrel and rotor by contacts 23, 24.
