  • Process and apparatus for the production of strands for Bowden cables
    Patent number: 4680952
    Abstract: A process for the production and further processing of strands for Bowden cables of several wires stranded together by twisting, comprising dressing the strands after stranding between reversing rolls, subsequently stretching and again dressing between reversing rolls. Dressing is effected prior to stretching in several stages with decreasing bending radii and after the stretching again in several stages with increasing bending radii, while the stretching is performed with a force approximately within the area of the elastic limit, corresponding to 45% to 70%, preferably to 55% and 65% of the ultimate tensile strength of the strand.
