Abstract

PROBLEM TO BE SOLVED: To obtain a device capable of automatically cutting and discharging flash scrap and above all suitable for treating continuously generating flash scrap by providing a scraper slidingly contacting an outer peripheral surface of a wheel and a rotary scraper having blades neiboring the scraper and intermittently sliding on the wheel. SOLUTION: For example, of an Al rod 5, a metallic material supplied to a conformer as metallic outer coating around a wire 6, a part is not submitted to actual use but the remaining part is sent off to the side of the rotary scraper 3 as flash scrap 7. On the other side; regarding the rotary scraper 3, when the blade at the tip end just comes to contact or approach the wheel 1, the flash scrap 7 is pushed and cut out. In consequence, even when the flash scrap 7 generates in a long continued form, it is cut out at a fixed intervals. At a place where the blade does not touch the wheel 1, the scraper 2 just below the rotary scraper 3 scrapes up the flash scrap 7, which is cut out by the blade in the subsequent cutting action.
