PROBLEM TO BE SOLVED: To protect the surfaces of bent sheets from being scratched by a method wherein a movable bed panel is bonded through hinges to a fixed bed panel and, on the top surfaces of both the bed panels, sheet stoppers are provided through positional adjusters respectively slidably normal to the direction of the rotating shaft of the movable bed panel and, in addition, an angle adjusting bar is planted on the top surface of the fixed bed panel. SOLUTION: In this device, a fixed bed panel 1 and a movable bed panel 2 are bonded through hinges 3 provided on both the side faces so as to turn the top surfaces 1s and 2s of both the bed panels into a same surface (s). In addition, the movable bed panel 2 is made turntable to the fixed bed panel 1 within the range of the dihedral angle formed by the bet panels of 0-180 deg.. Further, on the top surfaces 1s and 2s, every two stripes of recessed rails U1 and U2 are provided normal to the direction of the rotating shaft of the movable bed panel 2. Furthermore, strip plate sheet stoppers S1 and S2 are provided through positional adjusters V1 and V2 so as to prevent a plastic sheet P from moving at its bending. In addition, at the upper side 1s outside part of the fixed bed panel 1, an angular adjusting bar 4 is planted so as to control the dihedral angle formed by both the top surfaces 1s and 2s at the turning of the movable bed panel 2. |
