<p>A control device for a cutting blade (1), particularly for cutting-off machines for logs of web material, comprising: measuring means (15) able to detect deformation values ( lambda ril) on at least one portion of the cutting blade (1), comparison means (17, 26) to compare the deformation value ( lambda ril) measured by the measuring means (15) with at least one threshold deformation value ( lambda max, lambda min) set by an operator, and actuator means (20) to send, according to the signals coming from the comparison means (17, 16), control signals (C1, C2) to the motorization (21) of the machine, to control the start-up and/or the stop of said motorization (21). <IMAGE></p> |
