つてくる。 Subsequently, the head body 12 and the suction nozzle 15 are moved in the trimming direction at a speed of 7 m 3 /min. At that time, the skin material Wa and the foam material Wb are melted and cut by the heat of the irradiated CO 2 laser beam Ya, and resin gas and tar-like molten substances are generated during the melting. The object M is blown up onto the surface of the workpiece W by the blowing of the assist gas G.

It is sucked together with the surrounding air from 15a, passes through the inside of the suction nozzle 15, and is guided to the suction device to prevent the product M from adhering.
