PROBLEM TO BE SOLVED: To provide a biaxial extruder wherein pointed ripples do not generate on the outer peripheral surface of a molten article which passes through a discharging port. SOLUTION: This biaxial extruder is equipped with a body 3 to which an end plate 5 wherein a raw material feeding port 4 is provided on the top of one end side, and at the same time, a plurality of discharging ports 13, 14, etc., are provided on the other end side, is attached, a pair of rotating shafts 17, 18 which are rotatably provided in the confronted directions in the body 3, and feeding screws 201 -206 which are provided on the rotating shaft, and the discharging ports of the end plate 5 are formed of a cylindrical part 81 which protrudes to the downstream side from the end plate 5, and a jacket 68 for the heating of raw materials is provided in a manner to surround the outer periphery of the cylindrical part 81 for this biaxial extruder. For such a biaxial extruder, a jacket 76 for the cooling of raw materials is provided in a manner to surround the outer periphery of the cylindrical part on the downstream side from the heating jacket 68. |
