DIFFERENTIAL PRESSURE-SHAPING APPARATUS AND DIFFERENTIAL PRESSURE-SHAPING METHOD

摘要

To provide a technique which can improve the accuracy of differential pressure-shaping positions.SOLUTION: When a first mark detection unit U31 detects a mark M1 on a first side S1 of a sheet SH1 a first edge portion SH11 of which is being transported by a first transport unit U11 to a downstream side D1L, a differential pressure-shaping apparatus 1 stops the transport of the first edge portion SH11 when the first edge portion is transported by a preset distance (L2) after the mark has been detected. When a second mark detection unit U32 detects a mark M2 on a second side S2 of the sheet SH1 a second edge portion SH12 of which is being transported by a second transport unit U12 to the downstream side D1L, a differential pressure-shaping apparatus 1 stops the transport of the second edge portion SH12 when the second edge portion is transported by a preset distance (L2) after the mark has been detected. When the transport of the first edge portion SH11 and the second edge portion SH12 is stopped, the differential pressure-shaping apparatus 1 causes a differential pressure-shaping unit U2 to shape the sheet SH1.SELECTED DRAWING: Figure 13
