METHOD AND DEVICE FOR THE MANUFACTURE OF MULTIPLE GROOVED WIRE

摘要

A plurality of rollers (114,116, 214, 216) for producing longitudinal grooves (120, 122, 220, 222) in an elongated metal substrate (w), the plurality of rollers comprising a first set (114) and a second set (116) 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.
