Abstract: A trouser treatment device including a trouser supply module including transport for transporting each of the trousers from an entry to a supply exit, an opening module of the waist of one of the trousers, arranged in the trouser supply module, and a transport module with fastening clamps that hold the trousers with the waist open by the waist and that carries the trousers from the supply exit to a trouser holder of a work station with a processing device and a rotation element able to rotate the trouser holder according to a vertical axis. The trouser holder includes, on each leg, an outer rod and an inner rod, which deploy sideways, and a third rod, arranged between the other two, which is deployed forward or backward.

Abstract: A device for the laser treatment of trousers, including a laser beam generating equipment suitable for emitting the laser beam in any direction within an emission pyramid with an emission axis and two opening angles, and a work station with two mannequins, where each mannequin includes two legs. Each leg defines a longitudinal axis, and the two longitudinal axes of each mannequin define a mannequin plane. Each of the mannequins is oriented towards the equipment so that the emission axis strikes the mannequin plane at an angle of less than 90° and each mannequin has at least one of its legs within the pyramid.

Abstract: The method comprises: detecting the positions (uo, vo) and (u1, v1) of said photonic beam (L) according to the coordinate axes X, Y on a first and second plane XY, which cut an optical axis X at a first and second point, respectively; comparing the results of said positional detections (uo, vo) and (u1, v1), and: if there are discrepancies which lie outside the margin of error (p), adjusting the angle of the photonic beam (L) according to the angle ? and/or the angle ? in order to overcome said discrepancies; or if there are no discrepancies which lie outside said margin of error (p), considering the angle of said photonic beam (L) as being properly adjusted. The system is adapted to implement the method set out by the invention.

Abstract: A method and a system for laser marking a substrate for irradiating an area of a substrate with energizing radiation generated by an energizing radiation source to make said irradiated area require less laser energy to be laser marked; and irradiating a portion of said area with marking radiation from a marking laser beam generated from a marking laser source to laser mark said portion of said area. The irradiations from the energizing radiation source and from the marking laser source are at least partly overlapping each other in space and time, and are implemented by moving both the energizing radiation and the marking laser beam towards various areas of the substrate and portions thereof, respectively, in a synchronized manner.

Abstract: The method comprises: detecting the positions (u0, v0) and (u1, v1) of said photonic beam (L) according to the coordinate axes X, Y on a first and second plane XY, which cut an optical axis X at a first and second point, respectively; comparing the results of said positional detections (u0, v0) and (u1, v1), and: if there are discrepancies which lie outside the margin of error (p), adjusting the angle of the photonic beam (L) according to the angle ? and/or the angle ? in order to overcome said discrepancies; or if there are no discrepancies which lie outside said margin of error (p), considering the angle of said photonic beam (L) as being properly adjusted. The system is adapted to implement the method set out by the invention.

Abstract: Laser image projection system applicable to the marking of objects and method for generating holograms may include a reflection spatial light modulator, laser beam irradiating means for irradiating laser light onto the reflection spatial light modulator at a certain incidence angle, controlling means connected to the reflection spatial light modulator, the controlling means controlling said reflection spatial light modulator to define a holographic diffraction pattern corresponding to the desired optical image intended to be irradiated onto the object, and focusing means for performing a Fourier transform of the phase-modulated laser light to transform it into the optical image and irradiate it focused onto said object, wherein said focusing means includes a Fresnel lens holographically defined onto the reflection spatial light modulator to thereby improve an efficiency in the use of the light energy irradiated by said irradiating means.

Abstract: The invention relates to a system for marking or perforating by laser and to a marking or perforation process in said system, which is comprised of at least one laser (19) which produces a beam, a supply unit for at least one laser (19), a control means (12) with a control program which controls the laser (19), a deflector (16) particularly an optical-acoustic deflector which produces different beam deflection angles, in this case an optical system traversed by the beam, which produces a marking or a perforation configured like a matrix of points (n.times.m) on a surface of a product in relative motion between the product to be marked or perforated and the laser beam. The supply unit and/or the deflector (16) may be controlled by the control program. The system of the invention provides for a dynamic control of the marking or perforation resolution in a vertical direction.
