METHOD AND DEVICE FOR MAKING A FLEXIBLE TUBE BODY |
摘要 |
The invention concerns a method for the continuous production of a flexible tube body from two stapled wires (9, 10) individually bent in bending means (7, 8), three stitches, unsupported by a mandrel, and such that the wires (9, 10) remain constantly in contact so as to optimise their resistance to external pressure. The bending means (7, 8) can be arranged with respect to each other without affecting the bending adjustment. The method consists in stapling the two spirals by elastically deforming the turns so that one crosses the other to cause the wires to overlap partially. The invention also concerns an equipment for producing such a flexible tube body. |
