    Abstract: A steel cord effective for reinforcing a super-large off-road tire wherein strands made by simultaneously twisting together 3 to 6 steel wires in the same twisting direction with the same pitch length are used and the steel cord is made by twisting together 3 to 6 such strands in the same direction as the twisting direction of the strands and with the same pitch length. Each of the steel wires constituting the strands continuously has a small wavy pattern of a pitch length smaller than the lay length of the strands and therefore each of the strands has a compound pattern comprising a wavy pattern formed by the twisting and said small wavy pattern and in a gap is formed between steel wires each of the strands by the small wavy pattern. The lay length P.sub.1 of the steel cord is 8 to 15 times the steel cord diameter D and the elongation on breakage by tension of the steel cord is over 5%.

    Abstract: A steel cord comprising a number (between 3 and 27) of element steel wires tightly twisted at a regular pitch P between 5 and 20 mm in the same direction. Each wire has a diameter d between 0.1 and 0.4 mm. At least one of the wires includes a spiral portion having a spiral pitch P1 between 0.1P and 0.7P and a spiral diameter d1 between d+2/100 mm and d+2/10 mm. At least one other wire includes a straight portion. At any cross section of the cord, 1/4 through 2/3 of the wires is/are spiral and the other wire/s is/are straight. The stretch of the cord under a load of 5 kg is between 0.10 and 0.40%. A method of producing a steel cord comprises supplying a number of element steel wires, forming at least part of at least one of the wires to be spiral, and tightly twisting the wires. An apparatus for producing a steel cord comprises feeders supported by a frame, each feeding an element steel wire along an axis, a tension device for applying a tension to the wire from at least one of the feeders, a spiral device having pins which extend across and are spaced along an axis, so that at least one of the wires from the tension device turns alternately over and under the pins, a strand device rotatable on the axis, so that the wires are twisted to form a strand, and a take-up device to take up the strand.

    Abstract: A method of manufacturing wire ropes, in which a translational motion is imparted to wires (2) fed from reels and before the twisting of these wires around the core member (11) they are given a residual deformation by way of subjecting each wire (2) to a flat bending on one support (3) and to a helical bending in the direction revolved relative to the direction of the flat bending. A wire rope twisting machine in which a device for imparting a residual deformation to the wires (2) is secured on an output portion of a hollow shaft (14) coaxially therewith includes a body (23) on which are installed for each wire (2) two supports (26, 27) arranged in succession. The first support (26) is installed for free rotation about its geometrical axis (28a) and the second support (27) is installed for free rotation relative to its geometrical axis (31a) and for a setting turn about an axis (33a) disposed perpendicularly to the geometrical axis (31a) of the second support (27).

[Also in Division D1] A stranded cable for prestressing concrete comprises wires 10, 11 laid helically, but retaining the same cross-sectional orientation throughout the length of the strand, i.e. being not pivoted about their own axes. Any crosssection other than a simple circle, may be used, and other examples shown are elliptical, triangular, square, hexagonal and oval. It is stated that a wire may contain 0À8% carbon, 0À7% Manganese, 0À01% Phosphorus, 0À033% Sulphur and 0À2% Silicon.
