PURPOSE:To prevent foreign matter from catching on a roller or in a wire receiving circumferential groove so as to prevent a wire from coming off and so as to stabilize cutting. CONSTITUTION:Partition plates 5, 6, with which end edges 5a, 5a are brought into sliding contact, are arranged in rows of wires SL positioned between a roller 32 and work (w), and the work (w) and a roller 33. Foreign matter adhering to the rows of wires SL is scraped off by means of the partition plates 5, 6, while the foreign matter is prevented from invading wire receiving grooves 34 in the rollers 32, 33 and from catching on between the rollers 32, 33 and the wire S, so that the wire is prevented from coming off, while cutting is stabilized. |
