Abstract
A plurality of rollers for producing longitudinal grooves in an elongated metal substrate, the plurality of rollers comprising a first set and a second set of rollers, the plurality of rollers having groove-forming fluted edges thereon. The plurality of rollers are aligned circumferentially around and parallel to a longitudinal axis of the elongated metal substrate, wherein the plurality of rollers are configured to produce an odd number of grooves distributed asymmetrically about a circumference of the elongated metal substrate.
Claims20
A method for forming a multiple grooved wire, the method comprising:
- pulling a wire through a first set of rollers, the first set of rollers having groove-forming protrusions thereon, wherein the first set of rollers forms grooves in the wire, the first set of rollers defining gaps between the grooves;
- and
- pulling the wire through a second set of rollers, the second set of rollers having groove-forming protrusions thereon, wherein the second set of rollers forms grooves in the wire in the gaps formed by the first set of rollers.
A device for producing longitudinal grooves in an elongated metal substrate, the device comprising:
- a first set of rollers;
- and
- a second set of rollers, wherein the first set of rollers produces one of an even and an odd number of grooves in the elongated metal substrate and the second set of rollers produces an other of the even and the odd number of grooves, the first and second set of rollers having groove-forming protrusions thereon and aligned circumferentially and parallel to a longitudinal axis of the elongated metal substrate, wherein the first and the second set of rollers are configured to produce an odd number of grooves distributed asymmetrically about a circumference of the elongated metal substrate.
