Abstract

Procedure for manufacturing flexible tubes of soft weldable material, characterized in that two or more tapes of the weldable material are advanced around a forming tube, welding the longitudinal edges of each tape, with the longitudinal edges of the adjacent tapes, advancing the tapes simultaneously and intermittently a distance virtually corresponding to the extension of a plurality of forming devices equal to the number of tapes, in the longitudinal direction of the forming tube, the forming devices moving, during the phases of momentary stop of the tapes, towards the tube conformer to make the corresponding tape surround its respective part of the tube, so that the adjacent edges come into flat contact with each other, said edges then being welded together in a known way to form the flexible tube.
