Abstract

PURPOSE: To make easy the manufacture of very light metallic wire for use in eyeglass frame, by the dies-drawing of a clad metal tape with noble metal or noble metal alloy at its outer surface to form a slotted tube, then by curling both ends of the slot inward to form a tubular wire.
CONSTITUTION: Nickel-chromium alloy 3 is joined metallurgically with noble metal or noble metal alloy to form a clad metal tape 5 of a thickness not larger than 1/20 times the breadth. The tape 5 is subjected to a series of dies-drawing while being suitably hot treated to form a slotted tube having a nearly circular section and having noble metal or noble metal alloy rod 5' at least at its outer peripheral surface. The right and left ends 5a of the slot are dies-drawn to form symmetrical curls 6 on both ends, whereby the slot is closed to produce tubular metallic wire 7, or slotted tubular wire 7' having a box-shaped section is manufactured.
