のまま用いて製造することができない。 As an example of a flexible composite pipe, as shown in FIG. Layer metal reinforcement layer on top of cross section inverted U
The second metal band 2' is formed by winding the metal band 2' in a spiral shape so that the legs 2'a of the metal band 2' extend over adjacent turns of the metal reinforcing layer 4 of the first layer and are inserted into the recess 2b.
It has been proposed to have a metal reinforcing layer 4' of the layer. In FIG. 1, reference numeral 5 indicates an external metal reinforcing layer, and 6 indicates a plastic jacket. Such flexible composite pipes are generally manufactured by rotatably supporting a plastic pipe and providing a metal strip around the plastic pipe and wrapping it in a spiral shape. However, with this method, it is not possible to rotatably support a long plastic pipe, so it has not been possible to manufacture a long flexible composite pipe. This flexible composite tube also utilizes the principle of a cable taping machine to wrap metal around a plastic pipe running axially through the center of the rotating head, which is fed from a metal strip feeding means on the rotating head. It is conceivable to manufacture the strip by wrapping it helically around a plastic pipe. However, the metal strip of the flexible composite pipe has a large bending rigidity and cannot be manufactured using a cable taping machine as is.
