A method for predictive maintenance of a cutting unit of an automatic machine; the method determining, with a given frequency, the value of a characteristic quantity of the cutting unit related to contact between a cutting member and a counter-member; determining a curve for extrapolating the time pattern of the characteristic quantity value, and programming maintenance work on the cutting unit when the curve is outside a given acceptance range.

Method for predictive maintenance of a cutting unit of an automatic machine

A cutting device having cutting means for cutting a cigarette rod transversely along a cutting plane; a carriage for accompanying the rod through the cutting plane; an operating unit for moving the carriage back and forth in a travelling direction crosswise to the cutting plane; and a control unit, in turn having two proximity sensors, and which determines at least one fault on the operating unit as a function of recording signals emitted by the sensors.
