PROBLEM TO BE SOLVED: To obviate a rotary cutter, a feed roller, and a scraper and to eliminate labor for recovering dropped cut pieces in an extruder for rubber. SOLUTION: A method for extrusion-molding rubber comprises a first extruder 1 for extruding a rubber material by a screw 11, a die 2 which compresses the material extruded by the screw 11 of the first extruder 1 and supplies it continuously to a vacuum chamber 3, the vacuum chamber 3 which allows the supplied material to pass through without the material being contacted with the wall of the chamber 3, and a second extruder 4 for extruding the material supplied from the chamber 3 by a screw 41 and a molding machine for the method are provided.
