Abstract: A rotationally actuatable blade, particularly for automatic industrial slicing machines, the blade comprising a blade body which extends around a main axis and has a central region for fixing a spindle for actuating the blade with a rotary motion about the main axis and a perimetric region which ends toward the outside with a sharp edge, the transition region, comprised between the central region and the perimetric region, having a plurality of concentric circumferential bends which follow each other with alternating bending directions and with extensions, parallel to the main axis, which decrease from the central region in the direction of the perimetric region.

Abstract: A circular blade for slicing machines, particularly for slicing machines of the industrial type, which comprises a substantially disk-like central body and a peripheral annular body, which is integrally connected to a perimetric edge of the central body and forms a cutting edge of the blade. The peripheral annular body is harder than the central body and the central body has a plurality of radial stiffening ribs.

Abstract: A universal sharpening device for slicing machines with circular blade which comprises a supporting element, which is provided with elements for engaging the wing of a slicing machine, and an arm, which is associated with the supporting element and supports at least two grinding wheels. The arm is movable with respect to the supporting element from an inactive position, in which the grinding wheels are spaced from the blade of the slicing machine, to a first active position, in which one grinding wheel is moved into contact with the blade of the slicing machine, to a second active position, in which at least one other grinding wheel is moved into contact with the blade of the slicing machine.
