Abstract
The invention relates to a process and device for producing steel cord, in particular high tensile and ultra-high tensile strength cord. The aim of the invention is to provide for a high-quality production of in-out stranded wire with a core wire made of high tensile and ultra-high tensile wires, where large-scale spool fillings can be processed at an acoustic level of < 80 dB. This is accomplished in that a) the wires (8; 8') are drawn off at constant tension over the entire spool filling from mechanically brakable supply spools (2; 2') that are mounted essentially within a spool frame (1a) and that have a filling weight of > 50 Kg, and, through a glide and roll-off movement on a conical reversing sheave (7) at a single stranding point (9), the wires are stranded in a double twist to the structurally finished stranded wire (15); b) the structurally finished stranded wire (15) rotates about itself in passing through two synchronously rotating flyers (13a, 13b) at double the rotational speed of the flyers (13a, 13b); c) the individual wires (8; 8) are subjected to a predeformation before they pass into the stranding point (9); d) the structurally finished stranded wire (15) is subjected to a plastic deformation by overtwisting in the region between the stranding point (9) and the conical reversing sheave (7); e) the overtwist speed and the flyer speed are mutually adjusted at the same rotational speed ratio over the entire stranding process, including start-up as well as braking phase; f) to reduce its inner torsional tensions prior to being wound up, the stranded wire (15) is subjected to a defined increase in tensile force and to one or more overtwist and reforming processes and finally delivered at a constant take-up force to a controlled take-up stand (5).
