Abstract: A decoating method for the edge decoating of glass sheets, the glass sheets having at least on one of their two glass surfaces a protective coating in the form of a peel-off protective film or in the form of a polymer protective layer that cannot be peeled off, and preferably having a functional coating situated under the protective coating, the protective film being partially mechanically removed, in particular ground away, for the edge decoating, in the form of at least one film strip, laser traces being introduced into the protective film before the mechanical removal of the film strip, and the laser traces being introduced in such a way that the film strip is removed in the form of individual film strip partial pieces separated from one another by the laser traces; or the polymer protective layer being removed using laser radiation.

Abstract: In a method for producing a biocidal glass surface of a soda-lime glass, a glass surface of a soda-lime glass is indirectly or directly contacted with silver, silver salt, or silver ions and directly or indirectly heated using at least one laser beam of a laser such that an ion exchange of sodium ions from the soda-lime glass with silver ions of the silver ions or from the silver or the silver salt results and silver ions of the silver ions deposit in the region of the glass surface. Before being heated, the glass surface is coated with a transfer support including a layer of silver and a protective layer covering the silver layer, such that the protective layer directly contacts the glass surface, the glass surface then being heated using the laser. Also, a soda-lime glass having a biocidal glass surface is produced by the method.

Abstract: The invention relates to a method for producing a bird protection device and to a bird protection device. According to the invention, a method for producing a bird protection device is proposed, wherein the bird protection device is made of an at least partially transparent material and contains an optical structure visible to a bird's eye. Here, the method comprises a radiation input, wherein the radiation input is implemented on and/or in the partially transparent material for forming the optical structure. The radiation input is preferably laser radiation. Suitable lasers for the radiation input are, for example, CO2 lasers with a wavelength of 1064 nm, picosecond lasers with a wavelength of 532 nm or nanosecond lasers with a wavelength of 532 nm. In one embodiment of the invention, the bird protection device furthermore comprises an element for increasing the contrast, wherein, for forming the optical structure, the radiation input is implemented on and/or in the element for increasing the contrast.

Abstract: The invention relates to a device for detecting and/or recognizing markings, in particular for manual handling, comprising a camera for recording a marking and at least one illumination device for illuminating a marking, characterized in that, for detecting and/or recognizing markings (3) on/at/in transparent marking carriers (4), in particular having reflectively polished surfaces, the at least one illumination device (2) is arranged at a distance from the optical axis (A) of the camera (1) in such a way that the light reflection (5) generated by the at least one illumination device (2) at the surface of the transparent marking carrier (4) is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera (1).

Abstract: The invention relates to a method for the machine-reading of markings on/in transparent, especially pane-type, marking carriers, especially glass panes, according to which the marking carrier (2) is illuminated with UV light at least during the period of a machine-reading process of a marking, especially by means of a reading device (4), in order to increase the contrast between a marking (5) and the marking carrier (2). The invention also relates to a device for the machine-reading of markings in transparent, especially pane-type, marking carriers, especially glass panes, comprising at least one reading device (4) for markings arranged on/in a marking carrier, and at least one illumination device (4) is provided for increasing the contrast between a marking (5) and the surrounding transparent marking carrier (2) by illuminating the marking carrier (2) with UV light.

Abstract: The invention relates to a process for the marking of an object surface, wherein there is arranged in contact with, or a distance away from the object surface a carrier element, featuring on its side facing the object surface at least one metal coating embedded in other layers, whereby the layers in particular form a Low-E coating system and whereby a laser beam is directed onto the coating system and by reason of the laser irradiation material is transferred from the coating system onto the object surface to be marked, adhering thereto as a matrix with metallic nano-particles, whereby the matrix is formed of the substances originally present in the layers of the coating system. The invention furthermore relates to an object with an object surface marked according to this process.
