Abstract: A method for marking at least one portion of a surface of an object, said surface being made of a material that is paper, cardboard or fabric, the method comprising the following steps: heating the surface of the material by means of a heat source to a temperature lower than a temperature at which the visual appearance of the material changes; marking the heated surface by means of a marking laser, so that the light beam of the laser raises the temperature on the surface of the material enough to change the visual appearance of said surface; in which the marking laser is a laser with a light beam that belongs to the visible or ultraviolet spectrum.

Abstract: Method of controlling a laser marking matrix system, the matrix system comprising an N×M matrix of lasers to produce the laser marking, the method comprising the sequential transformation of at least two images to be marked into a series of marking commands according to an N×M matrix of dots, which comprises the following phases: division of a first image into a fixed portion and a variable portion, transformation of the fixed portion into a fixed matrix and the variable portion into a variable matrix, combination of said fixed and variable matrices, laser marking of the first image, processing of a second image, obtaining a new variable matrix which is added to the previous fixed matrix, producing a complete new matrix, laser marking of the second image.

Abstract: Method of producing equipment for marking products by laser, comprising the steps of: having at least one base plate; having various types of modules in which equipment components are grouped; having casings, rear covers and front covers that can be attached to said base plate; selecting modules from each of the different module types; removably attaching the selected modules to the base plate; attaching the casing, rear cover and front cover to the base plate.

Abstract: Device for the laser marking of products, of the type that comprises an outer casing defining at least one internal volume, the said internal volume comprising: at least one laser beam generating source, at least one optical system for the output from the laser, and electronic and control means of the device, the said casing additionally comprising at least one air outlet of the device, and at least one fan for generating a flow of cooling air from the generating source and the electronic and control means of the device through interior of the casing between the said air inlet and the said air outlet, wherein the said air inlet is more distant from the said laser output than the air output.

Abstract: Device and process for marking a moving object by laser A process for marking a moving object by means of a laser using a laser system with a laser beam with the ability to mark within a working area characterised in that: the position of the object to be marked is obtained by means of a sensor, and the speed of the object to be marked is varied in relation to the position of the object to be marked relative to the working area and/or the position of the laser beam within the working area.

Abstract: A laser apparatus includes a base frame extruded in one single piece of light alloy metal which determines a chamber intended to receive the laser generator cavity, incorporated within the chamber. The plane of the lower base of the chamber coincides with the base plane of the extruded base, and the lateral faces of the chamber are directed towards opposed lateral faces of partition walls of the extruded base, with controlled clearance to permit the expansion of the laser generator cavity without mechanical stresses being produced on same, capable of deforming it.
