摘要： A method is provided that includes providing a glass sheet of a thickness of at most 300 μm and irradiating the glass sheet with a pulsed laser beam. The laser beam has a light intensity inside the glass sheet leaves a filamentary damage along its path through the glass sheet. The laser beam and the glass sheet are moved relative to each other so that due to the pulses of the laser beam filamentary damages are inserted next to one another along a path running on the glass sheet. During the insertion of the filamentary damages, a tensile stress is applied on the glass at the filamentary damages and in the direction transverse to the path of the adjacent filamentary damages so that the glass sheet separates along the path during insertion of the filamentary damages.

摘要： A method for producing ultra-thin glass sheets is provided that results in glass sheets with high edge strength. The method includes: hot forming a continuous glass ribbon with a glass thickness from molten glass; annealing the glass ribbon with an annealing rate chosen based on the glass thickness; producing a laser beam focus area that is longer than the glass thickness; introducing filamentary defects into the glass ribbon using the laser beam so that the filamentary defects extend from one face to the opposite face and are spaced apart from one another along the breaking lines to produce transverse breaking lines and longitudinal breaking lines with margins each comprising a thickened bead; separating the beads along the longitudinal breaking lines and separating glass sheets by severing along the transverse breaking lines.

摘要： A suction gripping device for picking up a plurality of substrates which are flat and flexible includes: a base body, which defines a plane; at least one gas suction vacuum module which is arranged on the base body and has at least one gas suction opening configured for withdrawing gas by suction and for generating a first vacuum so as to suction a respective one of the plurality of substrates against the suction gripping device; and at least one gas ejection vacuum module which is arranged on the base body and has a gas ejection opening configured for ejecting gas and for generating a second vacuum so as to suction the respective one of the plurality of substrates against the suction gripping device.

摘要： A method for packing flat substrates, more particularly glass substrates, in a packaging box is provided. The method include the steps of: providing a base part of the packaging box, the base part comprising a lower wall and preferably four side walls, placing a flat substrate directly or indirectly on the lower wall of the base part of the packaging box, placing an intermediate layer directly or indirectly on the placed flat substrate, forming a stack of flat substrates and intermediate layers therebetween by repeating the preceding two steps, and setting a cover part of the packaging box on the base part of the packaging box.
