Incidentally, two or more clamping devices 8 may be provided in the transport direction as required. Next, the operation of the apparatus of the present invention will be described in the order of operations. The slab 1 is transported on the table 5 and arrives at the work area of the work arm 20 of the sagging removal device 2 and stops. The stop position at this time varies within the range of the stop accuracy of the table. Then, the arm 3 of the positioning device 7 rises, and the slab 1 is moved in the transport direction by the pressing claw 4 to perform positioning. When the position is determined, the arm 3 is retracted below the table 5, and the slab 1 at this position is sandwiched and fixed from both sides by the pressing claws 8A and 8B of the clamp device 8. In this state, the work arm 20 advances, and the sag removal by the blade 21 is started. When the sagging is completed, the work arm 20 is retracted, and the pressing claws 8A and 8B are also retracted to both sides of the slab 1, thereby completing a series of processing.
