Abstract (en)

[origin: WO2005005708A1] The invention relates to a method and a device for monitoring a moving material web (1), with at least a part (7) of the width of the material web being detected. In order to maintain the geometrical ratios between the individual elements of which the material web is constituted as largely as possible also in the image of the material web, an image of the material web is produced and the motion of the material web is detected in the same portion of the material web.
