Title: MACHINE FOR CUTTING PAPER LOGS
Abstract:
Cutting machine for the transverse cutting of logs (L) made of paper material, comprising a blade (4) driven by respective drive members (43; 46) adapted to move the blade (4) against a log (L) placed on a platform (1) that is configured to act as a supporting guide for the logs to be cut, comprising a transducer (6) adapted to detect vibrations of the blade (4) during the execution of each cut and also adapted to generate electrical signals whose instantaneous amplitude and/or frequency are related to the vibrations detected during each cut, and a control unit (5) programmed to compare the amplitude and/or frequency of the instantaneous signals generated by the transducer (6) with reference values contained in a database (DB) and to generate an alarm signal if the amplitude and/or frequency of the instantaneous signals generated by the transducer (6) are external to a predetermined range of values of the database (DB).
