PURPOSE:To fix a work without interference with a roller table even if the width thereof variously changes by constructing grippers in such a manner that the grippers can be driven by a gripper driving system. CONSTITUTION:The roller table 7 attached to a driving table 9 supports the work 2 and a processing head 8 moves in an X-axis direction while maintaining the relative position with the table 7. The head 8 independently moves in a Y-axis direction and executes the cutting of the work 2. Since the work 2 has various widths, the adjustment of the grip width according to the work width is necessary. The grippers 3 are moved cooperatively with the position meeting the width of the work 2 when the handle of the gripper driving system 12 for the grippers 3 is rotated. A detecting means 15 detects the position of the grippers by means of the dogs attached to the grippers 3 and the prescribed roller group lowers cooperatively with a lifting device which vertically moves the respective roller goups of the table 7. |
