Abstract

624,174. Extrusion apparatus. SOC. p.a. LAVORAZIONE MATERIE PLASTICHE. May 2, 1946, No. 13340. Convention date, June 21, 1944. [Class 87 (ii)] [Also in Group II] A mixing apparatus comprises a stationary screw 3 fixed in a chamber 1 forming a stationary coiled chamber through which plastic material is forced by an extrusion press to a die. A heater 2 surrounds the chamber and a heater may be arranged in a bore 5 of the hub of the screw.
