PURPOSE:To prevent a sheet from generating flaws by providing a lift type tapered feed roller in front of a piler and making an air nozzle movable in the plate width direction. CONSTITUTION:A feed roller 10 provided in front of a piler is made liftable by a screw jack 12 to adjust the advance angle of a sheet into the piler, the end sections of a roll barrel are inwardly tapered, the center section is made smaller than both end sections in diameter, and the guided steel plate is inwardly warped. Accordingly, the rigidity of the sheet is improved, and the buckling due to collision to an end stop is prevented. Next, a floating air nozzle 11 is made freely slidable in the width direction of the steel plate, and even if the steel plate generates snaking during the piling and is displaced from the center, the floating air nozzle 11 is moved in the lateral direction, and unbalance of the floating force is prevented and scratches are prevented. |
