Abstract (en)
[origin: WO2005033627A1] The invention relates to a measuring device for verifying the cut quality of a sheet, in addition to a measuring method for verifying the cut quality of a sheet, which permit the quality of the cut to be reliably verified. To achieve this, the measuring device is equipped with a transparent scanning support (3) for receiving a sheet (4) and a stop (1) for the latter, a scanning unit (15) comprising a scanning window (14) and a cover (21) for covering the sheet (4) that is held by the scanning support (3). The scanning window (14) covers the sheet (4), extending beyond the latter to form border areas (10, 11, 12, 13). The cover (21) has different reflection characteristics in relation to the sheet (4) in order to generate a high-contrast scanned image of the sheet (4) and the border areas (10, 11, 12, 13) between the sheet (4) and the scanning window (14). According to said method, the sheet (4) is positioned on a transparent scanning support (3) with the aid of a stop (1), is covered by the cover (21) and scanned with a scanning unit (15), the latter (15) scanning in the vicinity of a scanning window (14), which covers both the sheet (4) and the border areas (10, 11, 12, 13) that surround the sheet (4). Differences in contrast between the sheet (4) and the border areas (10, 11, 12, 13) are then recorded.
