FIELD: cutting.
SUBSTANCE: invention relates to a device for checking the state of blade sharpening, having a cutting edge delimited by two sides converging towards a plane that contains the cutting edge itself. Device comprises a processing unit and two control surfaces each of which is in contact with a corresponding side of said cutting edge, and is connected with a transducer, which produces an electrical displacement signal proportional to a displacement of the control surface with respect to said plane. Processing unit receives displacement signals and compares them, emitting an error signal if the comparison produces a value that exceeds a predetermined limit. Control surfaces are the surfaces that delimit an external groove of a roller that is free to move along an axis perpendicular to said plane and spaced from the blade by a certain amount to allow the cutting edge to pass in the groove.
EFFECT: as a result, checking is continuous, and the checking signal can be used at any time.
