<p>The machine (10) has a driving unit for driving cylinders, where contact actuating elements (21-23, 22', 23') are associated to zones at risks of the machine such that each zone at the risks is associated to the actuating elements. The actuating elements position the cylinders and/or rollers of the machine in an operating mode, and are associated to protection switches (24, 25, 25'), where the switches block an actuation mode by the actuating elements or each actuating element associated with the zone at the risks of the machine.</p> |
