A machine (10) for cutting and/or creasing a sheet (11) of relatively rigid material comprises movement means (17, 18) able to move the sheet (11) at least in a defined direction of advance, and cutting and/or creasing means (16) movable in a direction substantially transverse to the first direction of advance, and able to carry out on the sheet (11) at least a first working of cutting and/or creasing. The machine (10) also comprises a command and control unit (30), operatively connected to the cutting and/or creasing means (16), and able to selectively activate and/or move them according to a pre-loaded work program. The machine (10) comprises motion reversal means, kinematically connected to the movement means (17, 18), and means to rotate the sheet (11) by a desired angle before imparting to it a reverse motion. The command and control unit (30) is able to selectively activate and move the cutting and/or creasing means (16) according to the actual direction of advance determined by the reversal means, in order to carry out on the sheet (11) also a second working, subsequent to the first working, on the basis of the work program. |
