Abstract: A warp correction apparatus includes an elastic mat, a first sheet supply unit which supplies a first clean sheet on the elastic mat, a workpiece holding mechanism which supplies the plate-like workpiece (a frame unit) on the first clean sheet, a second sheet supply unit which supplies a second clean sheet above the first clean sheet, a pressure roller, a first elevator unit which moves the second clean sheet up and down, a second elevator unit which presses the pressure roller toward the elastic mat, and a roller moving mechanism. The pressure roller is moved along an upper surface of the elastic mat by the roller moving mechanism while the frame unit is sandwiched between the elastic mat and the pressure roller.

Abstract: A correction method includes a correction process for correcting warping of a plate-like workpiece including a frame portion and a plurality of flexure elements formed within the frame portion. The correction process includes arranging a first clean sheet on an elastic mat having a flat upper surface, supplying the plate-like workpiece on the first clean sheet, overlaying a second clean sheet from above the first clean sheet and the plate-like workpiece, lowering a pressure roller toward the elastic mat from above the second clean sheet, sandwiching the plate-like workpiece between the elastic mat and the pressure roller, moving the pressure roller along an upper surface of the elastic mat while having the plate-like workpiece sandwiched between the elastic mat and the pressure roller, and taking out the plate-like workpiece from the first clean sheet.

Abstract: A cutting jig for cutting a plate material positioned on a supporting surface, includes a jig body, a rolling blade rotatably supported with the jig body to roll on and cut the plate material, and paired holding parts rotatably supported with the jig body at respective sides of the rolling blade in a direction along a rotation axis of the rolling blade to roll on and hold adjoining portions of a cut portion of the plate material, each adjoining portion on which a stress acts due to the rolling blade cutting the plate material at the cut portion.
