Abstract
This flaw-treatment apparatus is able to prevent an increase in the number of flaw cuts by detecting false flaw-detection, and prevent the occurrence of die marks. For attaining these effects, this apparatus is comprised of: detection of the surface flaws of the wire-shaped metal by applying a flaw-detecting device, cutting and removal of the detected flaws by applying a flaw-cutting device, drawing of the flaw-free wire-shaped metal by applying a drawing device, spraying of lubricant on the wire-shaped metal, and removal of excess lubricant together with dust, and further grinding of the flaw-cut portion of the wire-shaped metal for obtaining adequate surface roughness before grinding.
