Abstract

PURPOSE: To simplify process by a method wherein material is in advance so processed that its hardness be lower than the product sponge rubber material.
CONSTITUTION: The material to be processed into sponge rubber is in advance processed to the optional hardness which is lower than that of sponge rubber material to be processed into a product. Said material is supplied from a supply outlet 5 of an extruder body 1 to be extruded by a screw toward an outlet to be molded to the sponge rubber material of desired hardness by adjusting the vacuum quantity to be absorbed by a vacuum pump freely regulating the first and second pressure regulating valves 9, 10 at a bent hole 6. Next the sponge rubber material extruded and molded into a prescribed form from the extruding outlet 24 is successively vulcanized and molded into a product having desired hardness.
