Abstract: The invention relates to an inspection device (42) for a converting machine (10), the inspection device comprising a camera (49) configured to capture an image of a portion of a blank (1) provided with a reference mark (30). The camera is arranged inside an external housing shroud (70), and wherein a thermoelectric element (78) is arranged between the camera and the external housing shroud.

Abstract: A quality control station (2) for a sheet element processing machine, the station having at least one camera (6) arranged for capturing images of sheet elements (4) transported through the quality control station (2), and further having a camera calibration system (10). The camera calibration system (10) having a target holder (12) for holding an optical target (14), and a drive (15) for the target holder (12). The drive (15) is adapted for displacing the target holder (12) between a rest position, in which it is outside of the viewing area (7) of the camera (6), and a calibration position in which it is arranged in the viewing area (7) of the camera (6).
