Abstract
PURPOSE: To obtain a pipe which is excellent in external pressure resistance and flatness strength and whose inner surface is smooth, by a method wherein a beltlike object is wrapped in a spiral so that the wrapping overlaps partially, a flexible core material encircled with beltlike objects is wound on the overlapped part, while the beltlike objects are joined together, and a projection lines being swelled up by means of the core material are formed.
CONSTITUTION: A beltlike object 2 made of polyethylene resin molten by heating is fed to a circumference surface of a rotating mandrel 1, a flexible core material 3 is fed parallel with the object 2, and they are wound in a manner to encircle the core material 3 in a part where a part of the beltlike object 2 is overlapped. A press roller 5 presses an overlapped part 6, and provides with a continuous concavity 5a in a periphery surface, acting as a channeled roller so that the core material 3 can be prevented from being squeezed. A periphery surface of a convexity 5b of the roller 5 presses the overlapped part 6 contacting said periphery surface, and the concavity 5a presses a part covering the core material 3 for joining together the molten beltlike objects 2. Additionally, the beltlike object 2 is adhered to the periphery surface of the encircled core material 3, and forms a spiral pipe 8 and a projection lines 9 on the periphery surface.
