(10) The guide device 8 prevents a plurality of roller members 30 arranged along the longitudinal direction of the wire M, and interference between the high position where the roller member 30 guides the wire M and the processing machines 1 and 2. Since the roller moving mechanism 31 that moves up and down to a lower position is provided and the roller moving mechanism 31 is individually operated, the guide member 8 guides the wire M according to the distance between the two processing machines 1 and 2. It is possible to support with certainty.
