Abstract:
A method of cutting, simultaneously on two axes (X, Y) perpendicular to each other, of a sheet or web of paper and other graphic or photographic substrates (10) with series of images, comprising the steps of feeding forward the substrate sheet or web (10) to a direction (F), detecting the speed of sheet or web (10) feed and the speed at which the distance is varying between image reference marks (11) and the ideal feed direction, determining a correct cutting line (TX) in a transverse direction to the feed direction (F) of the sheet or web by data processing according to trigonometric relations through a microprocessor to obtain the angle of parallelism defect of the image with respect to the ideal feed forward direction, aligning suitable mobile means (4) of transverse cutting with the desired cutting line (TX) by means (5) for shifting the transverse cutting means.
