Abstract
PURPOSE: To make the thickness of the noble metal base material of groove bottom the same as the thickness of other portions by providing a pre-working process between flat rolling and grooving at the time of flat rolling a round wire coated with the noble metal base material then grooving the same.
CONSTITUTION: A round wire 1 coated with noble metal or noble metal alloy la is flat-rolled to a wire 2 of an oval shape in section. Next, the outside of the wire 2 is molded to an inverted trapezoidal shape in section and at the same time, denting by which at least the deepest part is made into arc form is applied at least once to the top surface thereof by a roll, whereby a recess 3a is formed. Thence, grooving is applied by a finishing roll to the recess 3a of the wire 2' having been formed with the recess 3a, whereby a lens-holding groove 3 is formed to provide the rim wire 4' for spectacles.
