A lamination cylinder includes a surface structure, on which a plurality of craters is defined having a different geometry and a random distribution. Some of the craters are partially superimposed with respect to each other.

Lamination cylinder

A machine for the surface treatment of a cylinder includes a first operative station for supporting the cylinder and for bringing it into rotation around its longitudinal axis, and at least a second operative station cooperating with the first station for generating and emitting, by means of an optical fiber apparatus, pulsed laser radiations randomly striking the surface of the cylinder and defining a desired roughness on the same surface; the second station being adjustably coupled with the first station in a first direction parallel with respect to the axis of the cylinder and carrying one or more pulsed laser radiation emitting heads, and slidingly assembled with respect to the cylinder in a second direction perpendicular to the axis of the cylinder.

Operating machine and relative method for the surface treatment of cylinders

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.

Calibration device for measurement gauges of the diameter and other geometrical characteristics of cylinders

An apparatus for revealing the geometry of operative cylinders, in particular during the grinding operation of the same, includes a pair of movable clamps which can be moved away from and towards each other with respect to a fixed intermediate structure, the clamps having tilted surfaces in opposite directions to each other according to a swallowtail arrangement with respect to a cylinder being measured, positioned between them and between a surface of the fixed intermediate structure, the surfaces of the movable clamps and the surface of the fixed intermediate structure always being kept in contact with the cylinder, whether still or rotating, wherein the fixed structure also has, in its interior, parts of a group which interact with each other to correlate the movement of the clamps.
