Automatic cutting device for printed supports

An automatic cutting device for printed supports comprising:

• a feeding direction of a printed support;
• a first sliding plane surface in the feeding direction of the printed support to be cut;
• a second sliding plane surface in said feeding direction of said printed support after said printed support has been cut, wherein said second sliding plane surface is placed at a distance from said first sliding plane surface along said feeding direction and defines together with the first sliding plane surface a transversal cutting area having a largest dimension along a transverse axis, perpendicular to the feeding direction;
• at least two cutting units configured to be able to move along the transverse axis within the transversal cutting area so as to intercept and cut the printed support;
• and
• an electronic control unit configured to control the movement of the at least two cutting units;
• wherein
• the automatic cutting device further comprises an array of fins arranged in a comb, cantilever supported at said second sliding plane surface, wherein the fins of said array of fins are cantilever supported along a direction parallel to said feeding direction and are elastically constrained in said array of fins so that the fins can be elastically flexed along the transverse axis, wherein said array of fins:
• is configured to move, controlled by the electronic control unit, from a closed configuration, in which all the fins protrude from said second sliding plane surface towards the first sliding plane surface and occupy the transversal cutting area, to an open configuration in which the fins are retracted and leave free said transversal cutting area so as to allow undisturbed movement along the transverse axis of the at least two cutting units, wherein when the fins of said array of fins pass from the open configuration to the closed configuration and intercept said at least two cutting units placed in the cutting position, the fins come into contact with the at least two cutting units and modify the direction of the fins by flexing along the transverse axis, and
• the automatic cutting device further is configured, when in closed configuration, to sustain the printed support and/or cut portions of the printed support when a free edge of the printed support passes from the first sliding plane surface to the second sliding plane surface.
