    Abstract: A steel cord (114) comprises strength elements (100, 132) and having a length, a longitudinal central axis (112) and a cord pitch. At least one of the elements (100) has a projection on a plane YZ perpendicular to the longitudinal central axis (112). This projection takes the form of a curve with a radius of curvature which alternates between a maximum and a minimum. The curve further has a center of curvature. The radius of curvature and the center of curvature lie inside the curve so that a convex curve is obtained. The cord (114) is further characterized by one or both of following features:(i) the distance between two minimum radii of curvature of said curve measured along the longitudinal central axis (112) is different from half the cord pitch; or(ii) if all of said elements (100) provide a convex curve, at least one of said convex curves substantially differs from another convex curve.

    Abstract: An adjustable quill has a tubular housing, in both ends of which semicircular disks are adjustably mounted. The relative positions of the edges of the said disks serve to define opposite ends of a spiral preforming path for a wire strand being drawn through the tubular housing. The spiral preforming path within the housing between the adjustable end disks follows the outer circumference of a cylindrical structure extending between the two end disks and comprised, in a preferred embodiment for some purposes, of a series of rotatable disks, or, alternatively, for other purposes, of an extended rod or tubular member. In some embodiments the tubular housing for the adjustable quill may be omitted if a specially designed quill head is used to mount the quills. A quill head for adjustably mounting the adjustable quills is also disclosed to be formed from a series of circular plates mounted upon a shaft. The plates have apertures into which the adjustable quills are mounted. A chain and sprocket arrangement may provide uniform adjustment between the adjustable end disks of a series of adjustable quills mounted in the plates of the quill head.

    Abstract: A METHOD AND APPARATUS FOR IMPROVING THE PROPERTIES OF STEEL ROPE. THE STEEL ROPE IS SUBJECTED TO A FORCE OF TRACTION WHICH IS LESS THAN THE TENSION REQUIRED TO BREAK THE ROP, WHILE UNDER THIS TENSION THE ROPE IS PASSED THROUGH A HEATING ZONE SO THAT A GIVEN DEGREE OF STRETCHING WILL BE IMPARTED TO THE ROPE. PRIOR TO REACHING THE HEATING ZONE, WHERE A SUITABLE HEATING MEANS IS LOCATED, THE ROPE IS DIRECTED THROUGH AN UNDULATORY PATH BY AN ADJUSTABLE ROLLER MEANS CAUSING THE ROPE TO BE SEQUENTIALLY DIRECTED ALONG OPPOSED CURVES, SO THAT IN THIS WAY PRIOR TO REACHING THE HEATING MEANS THE ROPE IS STRESSED AND PRELIMINARILY HEATED TO A GIVEN DEGREE. THE TENSION IS APPLIED TO THE ROPE BY WINDING THE LATTER ONTO A DRUM WHICH PULLS THE ROPE THROUGH THE UNDULATORY PATH AND THE HEATING MEANS, AND BETWEEN THE HEATING MEANS AND THE TAKE-UP DRUM THE ROPE IS COOLED EITHER BY THE AMBIENT ATMOSPHERE OR THROUGH FORCED COOLING.

    Abstract: A cord reinforcing layer 30 can be highly efficiently fanned with easy control, and the amplitude and the wavelength of a wavy steel cord 32 can be made uniform throughout the cord reinforcing layer.When the wavy steel cord 32 (ribbon-like body 37) is wound plural times around the forming drum 35 to form the cylindrical cord reinforcing layer 30, the amount of extension is made decreased with distance from a set position P of a bead core 12 in the axial direction, and the amount of extension applied in advance to the wavy steel cord 32 in the vicinity of the set position P is approximated to the amount of extension according to the expansion and deformation of the wavy steel cord 32 at a position spaced away from the set position P, whereby at least either one of the amplitude and the wavelength of the wavy steel cord in the tire can be made uniform throughout the cord reinforcing layer 30.
