Laser device
A laser system for creating patterns on clothing includes a laser source; a phased array acousto-optic deflector (AOD) configured to control the direction and intensity of the laser beam; a computer comprising software for reading input files containing pattern designs and controlling the AOD to direct the laser beam according to the pattern designs; a fabric preparation station for washing and preparing fabric before laser treatment; a post-laser wash station for removing debris from the fabric after laser treatment; and a clothing finishing station for applying finishing touches to the fabric. The AOD includes an optical element having a surface with one or more steps formed thereon; a conductive layer formed on the surface with the steps; one or more crystals secured to each step; and electrodes positioned on each surface of each crystal.
MACHINE FOR THE TREATMENT OF PRODUCTS
The present invention relates to a machine for the treatment of products, in particular textile products, such as clothing, particularly suitable for being used for the application of engravings or decorative elements or motifs.
Furthermore, the present invention also relates to a method for the treatment of products, in particular textile products, such as clothing, by means of the aforementioned machine.
System and method of generating a pattern or image on fabric with linear laser irradiation, fabric made by said method, and products made with said fabric
A method of scribing abrasion aesthetics, patterns, images, serial numbers, ply markings and/or other information, such as sizing or care information, on fabric such as denim, before or during the fabric cutting process is provided. The method comprises loading the panel abrasion software, pattern marker software, and fabric scribing software; placing the fabric on a flat surface under at least one laser; laser scribing ply numbers, serial labels, fabric markers, and panel abrasions on the fabric; cutting the fabric into fabric lengths; spreading the pre-abraded and pre-marked fabric lengths on top of each other to create multiple plies in precise alignment; cutting shaped panels along the lines of the pattern marker with a conventional knife, laser, or other appropriate cutting tool; and stacking the abraded, labeled and shaped panels robotically or manually for sewing.
Laser Finishing of Apparel
Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes determining a fabric's response to a laser, capturing an initial image of a wear pattern on a garment, and processing the initial image to obtain a working image in grayscale. The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.
VISION GALVANOMETRIC LASER WITH LOCATION PLACEMENT CAPABILITY
A galvanometric laser for cutting and/or etching textile embellishments such as transfers or applique's and a method of operation thereof that is capable of visually capturing an incoming graphic image and referencing a cut pattern to the captured image and dynamically adjusting the cut pattern during cutting, etching and/or application of energy from the laser to thereby compensate for distortions in the fabric. The device includes a conveyor with an imaging station at which the graphic product is indexed under a high-resolution static camera with color recognition capability for the purposes of image capture. A high intensity bottoms-up light source resident at the imaging station provides ample illumination regardless of whether the design elements are face up toward the camera or face down toward the light source, or a combination of both. The system includes a computer at which the captured product image is analyzed, and the analytics are used to adjust the input cut file specifying the location and power settings for laser application. The product is then advanced in a controlled manner by means of the conveyor into a galvanometric cutting station where laser energy is applied. After completion the product is advanced out of the galvanometric cutting station for packaging.
POSTPROCESSING OF SEAT BELTS FOR ADDING DYE
Methods for marking a seat belt webbing with an infrared compound are described herein. The methods comprise ablating a surface of the seat belt webbing by directing one or more laser pulses toward the seat belt webbing; and coating the ablated surface of the seat belt webbing with the infrared compound, wherein the infrared compound increases absorptivity or reflectivity of the seat belt webbing to infrared radiation. Methods for optically monitoring operation of the seat belt webbing in a vehicle and distinguishing between proper positioning and improper positioning of the seat belt webbing are also disclosed.
METHOD FOR PRODUCING A DECORATIVE PANEL HAVING IMPROVED STRUCTURING
The present disclosure relates to a method for producing a decorative panel, comprising the following method steps: a) applying a decorative layer to a substrate, b) optionally applying an intermediate layer to the decorative layer, c) applying a cover layer to the decorative layer or the intermediate layer, and d) structuring at least one layer to be structured, said layer to be structured being selected from the decorative layer, the intermediate layer and the cover layer, characterised in that method step d) comprises the following method steps: d1) generating a laser beam; d2) dividing the laser beam into a matrix of a plurality of sub-beams; d3) guiding the matrix of sub-beams into a modulator for selective inactivation of individual sub-beams; d4) guiding the matrix of sub-beams from the modulator into an optical scanner, the matrix of sub-beams downstream of the modulator comprising all the sub-beams guided into the modulator or a reduced number of sub-beams; and d5) guiding the matrix of sub-beams from the scanner onto the layer to be structured; d6) the layer to be structured being negatively structured under the action of the sub-beams in order to generate a three-dimensional structure.
Cutting machinery laser system
A cutting apparatus comprising a cutting table and a first cutting material belt movably supported about the cutting table about a first roller and a second roller. A second cutting material belt is removably supported above the first cutting material belt about the first roller and a third roller, wherein the second roller is intermediate the first roller and the second roller.
Methods and apparatus for laser cleaning of fabric materials
Disclosed are methods and apparatus for cleaning a substrate, such as a fabric material, involving the application of optical energy to the substrate, typically in the form of a beam of light, where the energy of the beam causes removal of the contaminant from substrate, such as from the fibers of a fabric material. The cleaning may occur via any mechanism, including one or more of, alone or in any combination, ablation, melting, heating or reaction with the substrate or contaminant or agent introduced to aid in the cleaning. The optical energy is typically applied to a selected area of the substrate (e.g., as a beam), and the substrate and beam or optical energy source moved relative to one another so as to clean a larger area of the substrate, either by moving the substrate or the beam, or both. Movement of the beam with respect to the substrate can be attained through a beam scanning mechanism or through movement of the optical source itself.
CUTTING MACHINERY LASER SYSTEM
A cutting apparatus comprising a cutting table and a first cutting material belt movably supported about the cutting table about a first roller and a second roller. A second cutting material belt is removably supported above the first cutting material belt about the first roller and a third roller, wherein the second roller is intermediate the first roller and the second roller.
