摘要： PROBLEM TO BE SOLVED: To prevent short passing of an unmolten substance and retention of a resin from occurring and to perform miniaturization. SOLUTION: A pair of different diameter screws 2 being freely rotatably arranged in a heating cylinder 1 each have a different diameter part 3 consisting of a tapered part 3a contracted toward the downstream side and a cylindrical column part 3b successively arranged to this between a large diameter part 2a on the upstream side and a small diameter part 2b on the down stream side. A tapered ring 4 has a through-hole 4a wherein an upstream side tapered part 4b for forming a flow path consisting of a ring gap between the tapered part 3a and the cylindrical column part 3b is formed and an upper projected key 9 and a lower projected key 10 provided respectively on an upper slide bar 7 and a lower slide bar 8 are freely slidably fitted in an upper key channel 4d and a lower key channel 4e and divergence of the flow path is changed by moving linearly both parts in the orthogonal direction to the axial direction of the heating cylinder 1.

摘要： PROBLEM TO BE SOLVED: To make it possible to always maintain the excellent sharpness by cutting a purge resin material to small pieces without using a large driving force by repeatedly crossing the material to be externally discharged of a screw type kneader by a fine-wire. SOLUTION: A resin material of a molten state to be discharged from the end of the inner hole 2a of a cylinder 2 is fed from a lower end surface 6c into the inner hole 5 of a valve case 5 via the lower channel 6b of a piston 6, and discharged from the discharge surface 7b to the outer lower part via the exhaust port 7a of a cover 7. On the other hand, the extruded piston of one hydraulic cylinder 15b is returned, simultaneously the extruding operation of the piston to be returned of the other hydraulic cylinder 15b is repeated, and hence a fine-wire extended in a tensioned state is repeatedly reciprocated and crossed at the port 7a along the surface 7b. The resin material discharged via the port 7a is cut by the fine-wire repeatedly crossed, and dropped down as small pieces.

摘要： PURPOSE:To prevent the deterioration of the performance of a biaxial extruder even when the biaxial extruder and the whole succeeding device are installed on the same floor. CONSTITUTION:A biaxial extruder 20 has a cylinder 10, to which mutually parallel two screw holes 10e are formed, and screws 12 rotatably fitted to the screw holes respectively. A raw material charged from the raw-material charging port of the cylinder 10 is melted and kneaded by the screws 12, and extruded to the outside from a discharging path 32. The cylinder 10 is arranged so that axial surfaces passing through both axes of the screw holes 10e are made horizontal. In the discharging path 32, an opening section 10c on the screw hole 10e sides of the path 32 is disposed to the lower sections or upper sections of the screw holes 10e while the direction of the path center line of the path 32 is changed gradually into approximately the horizontal direction from the vertical direction, thus forming a discharge opening 10d on the reverse side to the opening section 10c so as to be opened to the side face section of the cylinder 10. Both screws 12 are rotated in the mutually different directions in the direction that the raw material is discharged toward the opening section 10c from the screw holes 10e.
