Abstract

960,575. Extrusion machines. HERMANN BERSTORFF MASCHINENBAU-ANSTALT G.m.b.H. April 2, 1963 [May 29, 1962], No. 12921/63. Heading B5A. In an extruder for thermoplastic materials such as rubber, having a feeding roller 1 driven by a high speed shaft 7, gearing 6 is provided in the interior of the roller 1 to transmit a low speed thereto. The gearing 6 may be of the planetary type as shown or of the stub-tooth kind.
