This method includes: an initial crack forming step of forming an initial crack (CR1) on a first surface (MG1) of a mother glass sheet (MG); and a laser irradiation step of irradiating the mother glass sheet (MG) with laser light (L) to cause a crack (CR2) to propagate along a preset cleaving line (CL) through use of the initial crack (CR1) as a starting point. The laser irradiation step includes irradiating a second surface (MG2) of the mother glass sheet (MG) with the laser light (L) to heat a surface layer (SL) and an inner portion (IL) of the second surface (MG2), to thereby cause, through a thermal shock caused by the heating, the crack (CR2) to propagate in an entire thickness direction of the mother glass sheet (MG) while propagating along the preset cleaving line (CL).

A method for producing an optical coupling element made of elastomer includes filling a free-flowing elastomer formulation or its constituents into a mold so as to produce a flat sheet whose thickness is adapted to a thickness of the optical coupling element that is to be produced. The elastomer formulation or its constituents is cured to form an inherently stable elastomer. Individual optical coupling elements are cut out of the flat sheet.

A method of cutting or scoring a substrate comprises: providing a substrate which has a maximum of radiation absorption at a first wavelength band; depositing on the substrate, in a predetermined pattern, a heating fluid which has a maximum of radiation absorption at a second wavelength band; and exposing a surface region of the substrate to electromagnetic radiation at the second wavelength band, the surface region including the predetermined pattern, to cut or mark the substrate along the predetermined pattern. The first wavelength band differs from the second wavelength band.

A multilayered sheet assembly for forming a sign on an object includes a carrier layer including a first side and a second side, a sign layer that is arranged on the first side of the carrier layer via a first adhesive layer, and a strip layer that is arranged on the second side of the carrier layer via a second adhesive layer in an adhesively separable manner. The sign layer carries a third adhesive layer at an exposed side that is across from the carrier layer to allow a sign that is formed by the sign layer to adhere to the object at the exposed side while releasing from the carrier layer.
