Abstract

Machine for the continuous production of impermeable tubes constituted by an inner sleeve or tube of permeable material reinforcement with a waterproof coating of synthetic resin or other flexible material, which comprises: an extrusion head with a perforation or cavity that traverses it longitudinally; a bar extending from the back of the extrusion head to hold the reinforcing tube outside the head to hold the bar; a mandrel extending from the barpet inside the head cavity; a core or matrix connected to the end of the mandrel within the cavity leaving an intermediate space; means for advancing the reinforcing tube through the head cavity by closing the mandrel bar and the core and means for injecting synthetic resin or other coating material into the head cavity through the reinforcing tube and for forcing this coating material through the tube of reinforcement to the mandrel so as to extend on the inner face of the reinforcing tube between the surface of the cavity and the core.
