<p>A system for scoring and/or perforating a laminar material is described. The system comprises a device comprising a rotatable drum (1) to which may be adhered annularly around the drum projecting elements (2,5), laterally spaced from each other. In addition, the system has a rotatable wheel (6) having a groove (8,9) provided around the rim of the wheel, arranged to cooperate with the strips of projecting elements. The device also includes with means for feeding laminar material between the drum and the wheel. When this happens, each strip of projecting element (2, 3) cooperates with the respective groove in the wheel so as to score or perforate laminar material passing therebetween.</p> |
