摘要： PURPOSE:To provide a reinforced resin bent tube, by a method wherein a thermosetting resin and a reinforcing material layer are formed around a mandrel in which a rigid core rod is inserted into an elastic cylinder, a shrink film is wound, the core rod is pulled off, said layer is bent under a condition that it remains uncured, and after said film is shrunk, it is cured. CONSTITUTION:A molding material 2, consisting of a thermosetting resin and a reinforcing material, is wound around a mandrel 1, in which a core rod 12 is inserted into an elastic cylinder 11, to form a pipe wall layer 3. A shrink film 4 is then rolled around the pipe wall layer 3. The core rod 12 is pulled off while the pipe wall layer 3 remains uncured, and the pipe wall layer 3 is formed into an uncured bend pipe in conformity with a curve mold 5. After, resulting from the heating of the uncured bend pipe, said film 4 is shrunk to adhere it firmly to the outer surface of the bend pipe, it is cured at a normal temperature or by heating, the elastic cylinder 11 is released from a mold, and the film 4 is peeled. This permits the production of a bent pipe having an inner and an outer surfaces which are both excellent in smoothness.

摘要： PURPOSE:To reduce significantly the abrasion of the surfaces of a screw, a barrel, etc. of a mixer, by feeding a thermosetting resin and a filler while they are being premixed by a mixer, and incorporating an aggregate at a position proximate to the tip of the mixer to form a molding material. CONSTITUTION:In the method for producing a composite pipe by winding a reinforcing material around a core cylinder 1 that is moved in the axial direction helically to form an inner layer 24, and feeding on the inner layer 24 a molding material 12 that comprises a thermosetting resin, an aggregate and a filler to form an intermediate layer 26, while the thermosetting resin 23 and the filler 21 are being premixed by a continuous type mixer 18, they are fed, and then the aggregate 22 is mixed from a feeding port 19 at a position proximate to the tip of the mixer 13 to form a molding material 12. Thus, the abrasion of the surfaces of the screw 16, the barrel 14, etc. of the mixer 18 can be significantly reduced.

摘要： PURPOSE:To make the surface of a tubular object smooth and improve, the accuracy of the outside diameter largely, by shaping a forming material layer on a core mold and hardening the forming material layer after passing the outside diameter gauge of the predetermined inside diameter. CONSTITUTION:After a mold releasing film 2 is wound on a core 1 which proceeds, rotating to the peripheral direction and reinforcing materials 3, 4, 5 impregnated with thermosetting resin is further wound on it, it is passed through an outside diameter gauge 6 reducing gradually its inside diameter at the entering section of the core mold so as to make a curved corner, at the same time a belt like film 7 being covered on the outside face of the tube, and hardened in the hardening oven 8. The tubular object 12 which is hardened and comes out successively is received at an appropriate receiving bed.

摘要： PURPOSE:To obtain a profile pipe at an inexpensive cost, by a method wherein an uncured pipe, which is continuously molded through the supply of a reinforcing material and curing resin on a cylindrical object formed with a beltlike sheet, is cut to proper lengths, and a profile-forming mandrel, in which its insertion end is shaped in a circle having a smaller diameter than an inner diameter of a cylindrical object, and it is increased in the diameter gradually in the insertion direction, is employed. CONSTITUTION:A cylindrical object is formed on a mandrel 1 in a manner to spirally wind a beltlike sheet 6 on the mandrel 1 which is turned by means of a retainer 2 and a belt 5 rotatively driven through pulleys 3 and 4, and an uncured pipe 10, which is continuously molded through the supply of a reinforcing material and curing resin, is cut to proper lengths. The uncured pipe is inserted over a mandrel 12 in which it has rotatably rollers 13 dispersively located in a projecting manner on its circumference surface, an insertion end is shaped in a circle having a smaller diameter than the inner diameter of the cylindrical object of the uncured pipe, and it, simultaneously, forms the uncured pipe in a profile when it is increased in the diameter gradually in the insertion direction so as to have the same circumferential length as that of the cylindrical object. This causes profile-forming of the uncured pipe to cure it and mold a deformed pipe.

摘要： PURPOSE:To enable a continuous profile-molding of an uncured pipe which is in a state to be susceptible to deform, by a method wherein kerves are formed in a cylindrical object of an uncured pipe, which is continuously formed as it turns spirally on a mandrel, and at a base end side of a core mold which is pivotably located at the forward end of the mandrel. CONSTITUTION:A beltlike sheet 8 is fed around a mandrel 1 at a base end side of a belt 7, which is rotatively driven by means of pulleys 5 and 6, to form a cylindrical object 9. A mold-releasing film 10 is wound around the cylindrical object 9 which is in a state to turn, and a molding material is supplied thereon to form an uncured pipe 11. In the case of, for example, a sandwiched pipe, a reinforcing material 12, for inner surface, a mixture 1 of curing resin and a filler, a protection material 14, and a reinforcing material 15 for outer surface are used as the molding material. The uncured pipe 11 moves from a forward end 1b of the mandrel to a base end 3a of a core mold, and kerves, which are susceptible to bring the pipe into deformation in a profile, are formed at the forward end 1b along the axial direction by means of cutters 4, and the pipe 11 is cured to the deformed shape of the core mold 3.
