Steel pipes are being used for transportation of C bodies, and recently the topography has been covered with glass pipes, which are easy to install.

L-n This 0J vulgarity'/f: It is advantageous to have a Flasnac hJ example tube. Generally, this neck is L1+4if+i
At the sending end 1, as shown in Fig. 1, an internal pressure reinforcing layer 4 is formed by wrapping several layers of metal bands in a conical shape on top of the plastic pipe 2, and furthermore, as shown in Figure 1, an internal pressure reinforcing layer 4 is formed. In order to withstand the axial tension, a plurality of gold threads or strips were twisted at a loose pitch and a plastic jacket 6 was applied. In this conventional manufacturing method, the metal strip is wrapped around the plastic pipe using a tape winding machine VC, but as the thickness of the metal strip becomes too thick, the force required for wrapping becomes too thick. Residual strain is left on the plastic pipe 2 due to torsional stress, which deteriorates the performance of the plastic pipe 2, and when the pipe is cut for the purpose of connecting the ζ end wire, the metal paulownia band remains with vM strain t1.
Therefore, there was a drawback that the mechanical strength of the end of the Song Dynasty was reduced by fraying.The purpose of the present invention is to prevent the plastic pipe V from being subjected to torsional stress, so that the former Emperor Jinchen could easily melt at the end of the Song Dynasty. It is an object of the present invention to provide a method by which a fluid transfer tube having ten or more performance can be manufactured in a single unit.

, the first roller 8 which is in contact with the inner surface VC of the gold lees band 3, and the gold &14' on both sides of this first roller. If 3 is in contact with the second and third rollers 9°9' and 3, which are in contact with the outer surface of the roller. The plastic pipe 2 rotates around its own center VC, and the reformer 7 rotates along a line parallel to the axis of the plastic pipe. fall t20
The rollers 9, 9' are positioned in the direction of the arrow with respect to the first roller 8 (71). The 191 feet are supplied to the 11t-C plastic pipe 2, and the metal paulownia belt is 3t in length.
The preform of this metal band is made to fit the diameter of the non-stick pipe 2, Cυ is also slightly embarrassing 1, and the diameter IJ2. With this kind of VC-J-, it is difficult to handle large punching force because the metal is wrapped with 4 layers and the ItG layer is applied to the glass pipe 2.

なく端末部の強度が同上する実益がある。In the VC twist of the present invention, the metal band forming the internal pressure reinforcing layer is preformed to have an outer diameter smaller than the outer diameter of the plastic pipe, and the metal band is preformed to have a smaller outer diameter than the outer diameter of the plastic pipe. Since there is no need to apply pressure, the performance is the same without causing any residual strain due to twisting in the glass pine.In addition, since Kinjima Wi applies compression stress to the plastic pipe, when the internal pressure of the glass pipe VL is 71) The strength is the same as above, and there is also the practical benefit that the strength of the terminal part is the same as above without the metal band coming undone when connecting the terminals.
