DISPOSITIVO PER IL CONTROLLO DI BOBINE IN ESAURIMENTO, IN PARTICOLARE APPLICABILE SU MACCHINE INCARTATRICI

摘要

A sensing facility that is integrated into a station from which strip material is fed to a wrap station, and/or into the roll and shaft from which the strip is effectively uncoiled, is designed to monitor an electrical impedance generated by the roll and shaft and/or linked to their overall radial dimensions. An output signal is triggered when the monitored level of impedance matches a selected reference value.
