Abstract

Process for the production of an altopolymer flexible tube for the conveying of fluids at high pressure, said altopolymer being chosen between elastomers and plastomers, which comprises the steps of: obtaining a tubular layer of altopolymer, applying on said tubular layer to minus two layers spaced apart from reinforcement elements, preferably of construction or braid or spiral; applying to the first such reinforcing layer, and before the application of the second layer, a layer comprising the altopolymer and textile fibers; applying on this last reinforcing layer to at least one cover layer of altopolymer or other material and, if necessary, vulcanizing or crosslinking the tubular assembly, characterized in that for the preparation and application of said intermediate layer is part of a non-woven fabric that has sponginess capable of allowing a perfect interpenetration of the altopolymer with it; the interpenetration of the altopolymer is operated with such non-woven fabric; a ribbon of the non-woven fabric thus treated is formed and such a tape is disposed in a manner known per se on the first reinforcement layer already applied, the second reinforcement layer then being applied on the tape.
