摘要： PURPOSE:To make it possible to form a pattern on the surface of a molded item, by providing the forward end section of an outlet for a resin with a projection extending toward the axis of a shaft of an extruder. CONSTITUTION:A thermosetting resin material fed from a hopper 1 is heated and melted in a cylinder by heaters 3, and is moved from the flight tip of a screw 4 helically to a smooth section 5 where the clearance formed by the screw flight is constricted and therefore the resin material is compressed and fused by the friction and resistance caused by the cylinder. The fused resin is shaped during the movement to the screw smooth section to such a degree that after the extrusion it can keep its shape, when a suitable back surface is given thereto by a back pressure giving apparatus 6 mounted to the cylinder tip so that the resin is compressed, fused and shaped wall, and at the same time a pattern is formed on the resin by a projection 7 at the forward end section of the outlet, and a pipelike molded item 9 having the continuous pattern 8 is extruded from the tip. In this case, since the pipelike molded item is extruded while being rotated, the pattern formed is helical.

摘要： PURPOSE:To obtain easily a resin pipe having a hollow rib that is seamless and uniform in thickness all round the surface by projecting the resin extruded from an extruder from starting as a hollow-ribbed resin pipe through the main slit and subsidiary slits of a rotary mold. CONSTITUTION:The resin 29' extruded continuously from an extruder 20 is revolved by the revolution of a rotary mold 21 in the peripheral direction while protruding. A hollow rib part 29b passing through a plurality of subsidiary slits 34 connected around the main slit 22 is provided spirally on the outer periphery of the annular part 29a that this protruded resin pipe 29 passes through the main slit 22 of the rotary mold 21. The resin pipe 29 protruded from the rotary mold 21 is brought into a negative pressure tank 24 from a rotary charging hole 25 rotating in the reverse direction to the rotary direction of the rotary mold 21 and at a speed equal to that of the rotary mold and subjected to sizing through the water. In this case, since the resin pipe is sucked radially by a suction hole 25b provided on the barrel of the rotary charging mouth piece 25, it does not deform. Thereafter, the resin pipe is extracted from a rotary extracting hole 26 and taken up by a resin pipe take-up unit 28.

摘要： PURPOSE:To make it possible to mold a two- or three-dimensional bent tube arbitrarily and also make it possible to mold a bent tube free from deviated thickness automatically. CONSTITUTION:A fixed baffle 17 and a rotational baffle 18 have axial holes 23 and 29 respectively into which a diametrically reduced section 24 of a mandrel 16 is inserted, and the fixed baffle 17 has a conical section 25 around the axial hole 23 and extending toward a screw 12 and flowing holes 27. The flowing holes 27 are open to an extruding clearance 26 between a head 3 and the mandrel 16 and are drilled circumferentially with a certain pitch between them. The rotational baffle 18 is arranged in front of the fixed baffle 17 and have flowing holes 28 having the same size as the flowing holes 27 of the fixed baffle 17, the pitch of the flowing holes 27 does not coincide with the pitch of the flowing holes 28 and the difference of the pitches becomes maximum at the opposite sides. By rotating the baffle having the flowing holes, the direction of the bend can be changed freely so that a desired two- or three-dimensional bent tube can be obtained.
