Abstract
947,386. Extrusion machines. FRIESEKE & HOEPFNER G.m.b.H. Feb. 15, 1960 [Feb. 17, 1959], No. 5253/60. Heading B5A. An extrusion screw 1, which may be axially adjustable, has a length-diameter ratio of from 1:1 to 5: 1, a helix angle of from 1 degree to 15 degrees and a flight depth of from 0.5 mm. to 6 mm. Breaker plates either of plano-concave or plano-convex shape or a breaker plate of uniform thickness but having holes of a differing diameter may be used.
