PROBLEM TO BE SOLVED: To manufacture sheet having a flat surface which are not parallel to each other by controlling the thickness according to the prescribed regulation to continuously change the sheet thickness by the function of the distance from an initial section when the sheets pass through a calibrated opening part. SOLUTION: A machining device is provided with a frame 11 to support a jaw 16 having two plates 161, 162 mounted opposite to each other. A calibrated opening part is regulated between two plates. The machining device includes a clamp 15 of a means to move sheets 2 relative to the calibrated opening part. The clamp 15 holds the sheets 2, and can be relatively moved to the plates 161, 162. That is, when the clamp 15 is advanced, a gap between two plates 161 and 162 is continuously changed, and the sheet thickness is changed while the sheets pass the calibrated opening part. |
