    Abstract: The present invention provides a yarn composed of polytrimethylene terephthalate fibers, particularly polytrimethylene terephthalate multifilamentary fibers having a single-fiber size in a range from 1 to 56 dtex, which are collected together to have a total size in a range from 2000 to 22000 dtex. Further, the present invention provides a racket string composed of polytrimethylene terephthalate multifilamentary fibers having a single-fiber size in a range from 1 to 56 dtex, which are collected together to have a total size in a range from 7000 to 22000 dtex, and a musical instrumental string composed of polytrimethylene terephthalate multifilamentary fibers having a single-fiber size in a range from 1 to 56 dtex, which are collected together to have a total size in a range from 2000 to 14000 dtex. The yarn according to the present invention is high in strength, elastic recovery and stress-retaining ratio as well as excellent in water resistance, softness and homogeneity of yarn properties. The racket string according to the present invention can be set across a racket frame, for example, for tennis or other, games under a high tension, whereby high resilience is obtainable when the string is set, and maintained for a long time. Also, this racket string is excellent in impact resistance, durability and water resistant. The musical instrumental string is stable in tuning over time and with a change in humidity as well as excellent in tunability.

    Abstract: A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled. The obtained cord (1), within each laying pitch and only under a traction condition involving a load not exceeding 5 kg, has at least one right cross section in which at least one wire (2a, 2b) is spaced apart from at least one of the adjacent wires so as to facilitate the rubberizing step, by enabling access of the blend to the cross section and penetration thereof along the cord axis. The cord is preferably used as a reinforcing element for the belt structure.

    Abstract: A high elongation compact helical steel cord with a high degree of elongation at break of not less than 5% has a (1.times.n) structure comprising three or more base wires which are helically preformed at a predetermined pitch and which are twisted in the same direction and at the same pitch so that the ratio P/D of the cord diameter D to the twisting pitch P is in the range of 8-15 with the base wire preforming pitch being shorter than the cord twisting pitch. The finished cord has a helical composite structure with its elongation under a load of 35 kgf/mm.sup.2 being 0.71%-1.00% and that under a load of 70 kgf/mm.sup.2 being 1.18%-1.57%. A radial tire is reinforced with the steel cord preferably as a steel belt cord. An apparatus for making the steel cord is provided with revolving preformers on the wire introducing portion of a bunching machine such that the bunching machine is rotated in a direction reverse to the rotational direction of the revolving preformers.
