METHOD FOR SEPARATING AND SUPPLYING SHEET MATERIALS, DEVICE THEREFOR, AND METHOD FOR APPLYING ADHESIVE AGENT TO SHEET MATERIALS

Gate blocks 18 are disposed to face each other, wherein the gate blocks 18 include inclined surfaces 18a respectively on inner wall surfaces at an upper end part of a case 7 in which multiple rectangular sheet materials W are stacked with four sides therearound being aligned in a sheet material stocker 3A. An uppermost group of sheet materials W including the uppermost sheet material W are curved so as to project upward, wherein each sheet material of the uppermost group has a predetermined curvature projecting upward. This structure makes it possible that when the uppermost one of the stacked multiple sheet materials W is taken out sequentially by a sheet material take-out means, each sheet material W is reliably taken out sequentially while double take-out of sheet materials is prevented even if each sheet material W has a relatively high rigidity.
