PURPOSE:To effectively straighten the distortion of the whole large sheet stock with a gap being caused between the sheet stock each other by piling up the large sheet stock by opposing the camber direction on each one sheet or plural sheets. CONSTITUTION:The large sheet stock 10 cutting in the width direction what is pulled out with rewinding by a payoff reel 1 by a thick plate shear 2 is piled up on a pallet 3 by a piling device. It is then transfered by a crane 8 together with the pallet 3, fed out each one sheet or plural sheets by a feeding device 4 and put to a roll over machine 5. In this roll over machine 5 the large sheet stock 10 is taken into a box 5a each one sheet or plural sheets by the rotation of a motor 5d. The large sheet stock 10 thus machined by the roll over machine 5 is piled up so that the mutual recessed faces and mutual projecting faces may oppose in the camber direction, then, a weight 6 is placed on the upper part thereof and the sheet 10 is put into an annealing furnace 7 with a truck to perform a stress relieving.
