摘要

Method for continuously producing tubes with an internal textile reinforcement and an external spiral in rigid plastic: said tube (1) comprising a tubular configuration with several layers of material; comprising: - the continuous production, by extrusion of a plastic material, of a tubular body (11) forming an inner surface of the tube (1); - the continuous braiding on said tubular body of a textile reinforcement layer (12); - the continuous application on said textile reinforcement layer (12) of a tubular covering (13) of plastic material forming an outer surface of the tube (1); and - the application on the tubular coating (13) of plastic material, of a rigid spiral (14) of reinforcement. The invention also comprises a system for the production of the tube and tube obtained. (Machine-translation by Google Translate, not legally binding)
