20160067821 | Process for Introducing a Weakening Line Through Material Removal on a Fibrous Coating Material, in Particular Natural Leather - Method for introducing a line of weakness through removal of material at a fibrous covering material, in particular a natural leather, in which a pulsed laser beam is guided a plurality of times over the back side in a line-shaped manner, wherein only one laser pulse is emitted for each impingement point, and the laser pulse causes an input of energy which leads to a heating of the fibrous covering material at the impingement point to a temperature above an ablation threshold and which maintains the temperature below a limit temperature in regions of the covering material adjoining the impingement point. | 03-10-2016 |
20140238962 | METHOD AND DEVICE FOR DISPOSING OF A SLUG PRODUCED IN A HOLE PUNCHING OPERATION ON A HOLLOW PROFILE - A method for disposing of a slug produced in a hole punching operation on a hollow profile is provided. The method includes the steps of providing a hollow profile; cutting at least one predeterminable hole or slug contour path into the hollow profile by means of a cutting device; leaving a residual web of the hole or slug contour path; moving a receiving device into the hollow profile; moving a punch from a first position into a residual-web-removing second position in such a way that the slug thereby produced is received by the receiving device; and moving the receiving device out of the hollow profile. | 08-28-2014 |
20140217103 | Apparatus for Laser Transmission Welding, Method for Laser Transmission Welding, and a Receptacle Which is Produced Thereby and is Closed by Sheet - A method for producing a receptacle which is closed by a sheet by transmission laser welding, and to an apparatus suitable to carry out same. The method and the apparatus are configured in such a way that a weld seam is formed between the wall structure of the receptacle and the sheet so as to be wider than the end faces of the wall structure. | 08-07-2014 |
20140110383 | Apparatus for Joining Two Workpiece Parts Having Regions With Different Characteristics by Means of Through-Transmission Welding - An apparatus for connecting two workpiece parts to form a workpiece by through-transmission welding by means of weld seams running in a preselected weld seam pattern in regions of the workpiece parts having different characteristics is provided. The apparatus has a laser beam source with a plurality of individually controllable laser beam emitters of different power which are arranged adjacently in an X direction and a homogenizer arranged downstream. At least two reflection channels are provided in the homogenizer which run parallel to one another in a Y direction and completely penetrate the homogenizer in a Z direction by a channel depth. | 04-24-2014 |
20130270238 | Apparatus and Method for Generating Separating Fissures in a Substrate - The invention is directed to an apparatus and a method for generating separating fissures in a substrate through action of a laser beam having an elliptical beam cross section with a beam spot length in a movement direction along a separating fissure to be generated in the substrate. The apparatus and method are particularly suitable for separating fissures which start or end on the substrate surface. A suitable diaphragm prevents radiation from impinging on the substrate before the start and after the end of the fissure. | 10-17-2013 |
20120085740 | DEVICE FOR SIMULTANEOUSLY PROCESSING THE CIRCUMFERENCE OF A WORKPIECE WITH LASER BEAMS - A device for simultaneously processing a circumference of a workpiece includes a plurality of laser-lens modules and a waveguide. The modules each include a diode laser and a lens system and is configured to emit a laser beam radially in a shared radiation plane. The waveguide includes a lower part and an upper part that together form a cavity enclosing the radiation plane. The laser-lens modules are configured so that the laser is reflected repeatedly between a bottom surface and a cover surface and propagates in an unaffected manner within the radiation plane so as to form a beam spot that strikes the workpiece with a homogeneous energy distribution. The beam spot has a height based on a distance between the surfaces and a width based on a divergence angle in the radiation plane and a distance of the module from the workpiece surface. | 04-12-2012 |
20110100963 | DEVICE FOR THE LASER TRANSMISSION WELDING OF COMPONENTS OVER A RING-SHAPED CONTACT ZONE - A device for joining by a laser beam two components along a ring-shaped contact zone jointly formed by the components using a laser beam where a first of the two components is transmissive for the laser beam and a second of the two components is absorptive for the laser beam. The device includes a receptacle configured to affix the absorptive component and an internal clamping chuck with at least one contact surface configured for placement on the transmissive component within a free inside area of the contact zone. The device also includes a pressure element with a free inside area that is larger than an extension of the contact zone, a laser source configured to emit the laser beam, a beam guide unit, a beam guide control unit, an external axial bearing, a rotatable holding wheel, and an internal axial bearing. The pressure element is connected to the internal clamping chuck via the external axial bearing, the holding wheel and the internal axial bearing so as to transmit to the internal clamping chuck contact pressure exerted on the pressure element. | 05-05-2011 |
