摘要：The invention concerns a method for the continuous production of a flexibletube body from two stapled wires () individually bent in bending means (), three stitches,
unsupported by a mandrel, and such that wires () remain constantly in contact so as tooptimize their resistance to external pressure. Bending means () can be arranged withrespect to each other without affecting the bending adjustment. The method consists instapling the two spirals by elastically deforming the turns so that one crosses the otherto cause the wires to overlap partially. The invention also concerns an equipment forproducing a flexible tube body.
