Abstract

PURPOSE: To inexpensively obtain the spectacle frames having good strength characteristics without impairing aesthetic feel by producing the spectacle frames by the special wire material whose sectional shape is periodically changed through plastic working.
CONSTITUTION: A wire material 2b which had possessed an even sectional area is worked to the special wire material 2a of periodically changing sectional areas by the rollers 1a, 1b in which the inside diameter lines 1c, 1d of roller grooves are not circular. The strengths of the respective portions of the special wire material having been worked in this way become nearly even. Next, the selection of which portions of the special wire material 2a in which positions of the front frame at the time of manufacturing the front frame by this special wire material enables the diversification of appearance to be obtained without applying machining and pressing at each of one front frame and without adding any decoractive pieces. In this way, the spectacle frames having good strength characteristics may be obtained without impairing aesthetic appearance.
