Abstract: A calibration device for gauges for the measurement of the geometrical characteristics of cylinders, such as the diameter, profile, rotundity and eccentricity errors, wherein such gauges include a pair of movable opposing arms equipped with feelers or sensors at their free ends, includes a pair of abutments reciprocally approachable and/or withdrawable by means of motors until a sample measure is obtained, as desired, within the measuring range of the gauge, on which the calibration device is assembled, revealed by means of measuring means cooperating with the abutments, such that consequently the feelers or sensors are respectively abutted or approached to the abutments to reveal the sample measure.

Abstract: A device and method for positioning and blocking steady rests for rolling milly cylinders in grinding machines and grinding machines employing the same. A positioning and blocking device for steady rests includes a substantially flat carriage including a translation mechanism and a blocking mechanism, wherein the blocking mechanism is magnetic.

Abstract: Measuring apparatus (50) of geometrical parameters of cylinders, rolls and similar elements (11), used for the rolling of flat products operating on a machine for the grinding of said cylinders with an autonomous movement, i.e. with a movement independent of the translation movement of the grinding wheel or other parts, characterized in that it comprises at least four sensors (54, 55), situated on a surface orthogonal to the cylinder (11) or roll and in that at least two of said sensors are situated in opposite positions.
