Abstract: The present disclosure provides an automatic cutting device for printed supports which allows to compensate for the space created between the sliding planes, so as to always sustain the support to be cut and allow it to pass from one sliding plane to another and reach the relative unloading rollers avoiding jam at the device outlet. This result is achieved by means of an array of fins supported at the second sliding plane, configured to move from a closed configuration, in which all the fins protrude from the second sliding plane towards the first sliding plane and occupy the transverse cutting zone, to an open configuration in which they leave the transverse cutting area free so as to allow undisturbed movement of the cutting unit. This array of fins in closed configuration sustains the printed support cut in the passage from the first sliding plane to the second sliding plane.

AUTOMATIC METHOD AND DEVICE FOR CUTTING SUBSTRATES HAVING PRINTED IMAGES
The invention relates to a method for cutting substrates with printed images in an automatic cutting device (100) provided with means for correcting alignment errors based on the detection of longitudinal and transverse cutting marks. The longitudinal cutting marks (LM) are provided with a discontinuity (N) arranged upstream of each transverse cutting mark (TM) with respect to a feeding direction (F) of a substrate (S) and spaced therefrom by a predefined known measure (d). The automatic cutting device (100) comprises a first optical unit (140) configured to detect the transverse cutting marks (TM) and a second optical unit (150) configured to detect the discontinuities (N) in the longitudinal cutting mark (LM). Since the velocity of the substrate is known, the control system activates the first optical unit (140) when the transverse cutting mark (TM) actually passed underneath it. Thanks to this combination of features it is possible to reliably solve the technical problem of detecting the transverse cutting marks by automatic cutting devices providing for errors correction.
