Abstract
Abstract A pipe of rubber or analogous material provided with a coupling flange which is constituted by one or several metallic rings secured to the pipe reinforcement, in which the ring is constituted by at least a series of concentric windings of a metallic element wound along spirals superposed one upon the other and firmly joined to one another; the method in accordance with the present invention consists of winding the metallic element in consecutive turns along spirals one upon the other, firmly connecting together the wound assembly and installing the same on the tubular member to form an integral part thereof.
