Abstract
A device and procedure for measuring the positions of sheets for a printing press by precisely determining and then correcting the positioning of sheets in a printing press. Edge areas of a sheet are reproduced, imaging data are transferred to a computer and the positioning of the sheet is detected on the basis of the imaging data by means of an image detection algorithm. Furthermore, the positions of the sheet determined are compared with the stored positions in the computer and position deviations are calculated from the comparison, which are transferred to the printing press and corrected by a sheet-registering device.
Claims8
Procedure for measuring positions of a continuous sheet (6) with an image detection device creating at least a partial image of the image area of a sheet (6), characterized by the respective creation of images of the edge areas (7,7′) of a sheet (6), transferred to a computer (20) by the imaging data produced by the imaging process, and determining the positions of sheet (6) on the basis of the imaging data by an image detection algorithm.
Device for measuring the positions of a continuous sheet (6) for a printing press or a copier with an imaging device for images of the sheet (6), characterized by a computer (20) for the evaluation of the images of the imaging device.
