ABSTRACT:
A method for producing a compacted wire strand substantially triangular in shape for making wire rope includes the steps of (i) unwinding a central group of wires from a bobbin, the central group being substantially triangular, (ii) winding up a first layer of wires around the central group, each wire of the first layer being released from a first set of bobbins mounted on a first cage rotating about the central group, (iii) winding up a second layer of wires around the first layer of wires, each wire of the second layer being released from a second set of bobbins mounted on a second cage rotating around the central group, the first cage rotating at a speed 1.6 to 1.9 times faster than that of the second cage, (iv) compacting the strand made of the first and second layers of wires in a substantially triangular die by pulling the strand therethrough, and (v) rolling up the compacted substantially triangular strand on a drum.
