Abstract
PURPOSE: To decrease the deformation resistance at the plastic working and make working easy by denting part of a hollow round wire or forming the hollow round wire to a tape of a flat section and gradually bending both right and left ends of this tape.
CONSTITUTION: A hollow round wire 4 is formed to a hollow wire 5 of a heart shape in section by heterogeneous rolls or the heterogeneous dies. The hollow wire 5 of which the section has been formed to a heart shape in this way is gradually plastically worked to be formed into an irregular shape rim wire 7 having a desired concave 6 on the inner side. The irregular shaped rim wire having been plastically worked in this way does not form any flaws at all on its surface nor cause material hardening and becomes a satisfactory irregular shaped rim wire 7 for spectacles. Since it does not gall the heterogeneous dies or heterogeneous rolls used in forming this, it makes working easy.
