Abstract

A device is provided for cutting paper and other graphic substrates (10) in roll on two perpendicular axes simultaneously with automatic errors correction, both in the feeding with respect to a direction (F) along the longitudinal axis (Y) of the substrate, and of the deviation of the image with respect to the edge of the substrate itself. For this purpose, a motor (5) is provided at the horizontal cutting unit (4), in addition to a drive motor (6), suitable for shifting the cutting path in order to make it coincide with the correct cutting line (T.sub.x). In the same way, for the longitudinal cutting assembly (14) along the (Y) axis, in addition to a motor (7) for performing the cut, a motor (8) is provided suitable for translating along the (X) axis the whole cutting assembly on the basis of lateral deviations detected by means of an optic cell (9), whose signals are processed by a microprocessor for the drive of the motor (8).
