Abstract: A method of providing a finishing pattern on a workpiece by a laser apparatus comprises providing a pulsed laser source, generating an output laser beam, a control unit for controlling the laser source and moving means for the laser beam. The method includes providing command instructions for operating the laser apparatus to scribe a predetermined finishing pattern on a workpiece and operating the laser source and the moving means to generate output laser beam for scribing lines of the predetermined finishing pattern on the workpiece according to the command instructions. The step of operating the laser source comprises at least one operating mode wherein the energy per unit surface delivered by the laser beam is variable, by changing the scanning speed of the laser beam and wherein the output power of the laser source and/or the duty cycle are maintained at a constant value.

Abstract: The invention relates to a process for preparing plates (22, 32) for cylinders (20, 30) to crease items (40) of the paper processing industry, the process comprising the following steps of: a) acquiring a pattern (50) of the creasing lines to be made on the item of the paper processing industry (40); b) making, on a reference sheet (70), through openings (74) depending on the pattern (50) of the creasing lines, the through openings being adapted to position creasing profile elements (25, 35); c) applying the creasing profile elements (25, 35) on the plate (22, 32) at the through openings (74) of the reference sheet (70), the reference sheet being positioned on the plate (22, 32).

Abstract: An apparatus for cutting and/or marking products using laser beams includes at least one laser light emitter moveable in a first direction along a cross-bar, the cross-bar being in turn moveable above a working plane in a second direction transversal to the first direction, and at least two motors for moving the laser light emitter and the cross-bar. The laser light source is positioned to direct a laser light beam onto said working plane. Advantageously the two motors are positioned fixed and are coupled together and both to the laser light source, and to the cross-bar, by a transmission belt.

Abstract: The present invention relates to an apparatus for cutting and/or marking products by means of laser beams. The apparatus comprises at least one laser light emitter moveable in a first direction (X) along a cross-bar, the cross-bar being in turn moveable above a working plan in a second direction (Y) transversal to said first direction (X), and at least two motors for moving the laser light emitter and the cross-bar. The laser light source is positioned to direct a laser light beam onto said working plan. Advantageously the two motors are positioned fixed and are coupled together and both to the laser light source, and to the cross-bar, by means of a transmission belt.
