Abstract
This flaw-removal device prevents overlooking of flaws in the automatic flaw-cutting process by rectifying the twist of a wire-shaped metal drawn from a cannon-shaped wire supply stand, further promoting efficiency in removing remaining flaws by applying the automatic flaw-cutting process and removing the uncut flaws by hand. In this invention, a twist-rectifying drum 3 is installed in front of a flaw-detecting device 4. It then becomes possible to rectify the twisting of the wire-shaped metal by winding the wire-shaped metal installed on a cannon-shaped wire supply stand around the twist-rectifying drum in a length longer than one turn of the coiled wire-shaped metal so that the wire-shaped metal is freely mounted on the drum. It also becomes possible to remove an uncut flaw by hand by installing a flaw-check and removal site 10 having a specified span between drawing dies 8 and a wire-drawing drum 9, and by stopping the portion of the wire-shaped metal having uncut flaws at the site 10.
