PLATE MANUFACTURING EQUIPMENT

PURPOSE:To remove the lateral shift of a grid by comprising a positioning device with a pair of guide belts that restrict the lateral movement of the grid and an air blowoff means that floats the grid between the guide belts. CONSTITUTION:When a plate 10 is guided into a positioning device, it is guided into the next cutting device so as to be inserted between guide belts 13 and 13. In this case, since the air supplied from a conduit 17 is blown out upward from the blowout port 16 of a bench 12, the plate is moved while it is being floated upward. As a result, even if the force that shifts the plate laterally is applied, the plate is regulated by the belts 13 and 13 without the positional shift of the plate and can be supplied to the cutting device while the center is being always aligned.
