摘要： A method for embossing a first grating in a planar material, by means of an embossing body and a counter embossing body, having each a hard surface, the first grating to be embossed comprising alternating substantially parallel and straight ridges and recesses, whereby the top surfaces of the ridges are intended to weaken a direct angular reflection of light by diffuse omnidirectional reflection, thereby producing a visible contrast between the ridges and the recesses. The method comprises on the embossing body providing a first plurality of obtuse pyramids intended to emboss the recesses of the first grating by exerting pressure on a first side of the planar material, the first plurality of obtuse pyramids forming first intermitted lines (row1, row2) corresponding to the intended recesses, and the pyramids in each subset corresponding to one of the first intermitted lines, being separated from each other by a determined distance that creates a gap in the line in such a manner that each gap from a line of pyramids may be connected to a corresponding gap from an adjacent line of pyramids by an imaginary line perpendicular to both of the adjacent lines; and roughening portions of the hard surface of the embossing body, the portions being located between adjacent lines of pyramids and intersecting at least one of the imaginary lines that connect one gap from one line to the corresponding gap from the adjacent line. On the counter embossing body, the method comprises providing a second plurality of obtuse pyramids intended to emboss the ridges of the first grating by exerting pressure on a second side of the planar material opposite to the first side, during embossing the obtuse summits of the pyramid pressing the planar material against a roughened portion of the hard surface of the embossing body, thereby satirizing the top surfaces of the ridges on the first side.

摘要： The device for satinizing and embossing flat materials comprises an embossing roll and at least one mating roll, said rolls being connected to a driving system and adapted to be driven individually or in common and to be resiliently pressed against one another while the individual teeth are flattened, and the embossing teeth being designed such as to produce in the corresponding locations of said flat material during its passage embossed marks whose appearance varies according to the viewing angle of the observer and/or the kind and/or the position of the lighting source, the embossing teeth which produce said variable marks having a different geometrical shape and/or surface than the satinizing teeth intended for satinizing. To this end, the surfaces of said embossing teeth and/or portions of the tooth space bottom are provided with microstructures. These microstructures allow producing largely forgery-proof marks which may furthermore provide a very decorative effect.

摘要： A method of embossing individually light reflecting areas on a foil material, the method comprising feeding a foil material into a roller nip between a pair of rollers, wherein the pair of rollers comprises a motor roller and a counter roller, providing each of the motor roller and counter roller at least in a determined perimeter with a plurality of positive and negative projections on a checkered layout whereby positive and negative projections alternate in axial and radial directions. The method further comprises that the plurality of positive and negative projections of the counter roller seamlessly and gaplessly join with those corresponding negative and positive projections of the motor roller at the intended embossing of the foil material, hence enabling a homogeneously jointed embossed polyhedron shape in the foil, and shaping each positive and negative projection on the motor roller as an n-cornered polyhedron with a specific surface intended to produce on the embossed foil surface a corresponding individually light reflecting area, for each positive projection its specific surface corresponding to its top side, and for each negative projection its specific surface corresponding to its bottom side.

摘要： The present application relates to a device for the mask projection of femtosecond or picosecond laser beams (2) onto a substrate surface, in which the laser beam (2) consisting of laser beam pulses is, at a location of the optical axis, formed to make laser beam pulses with an expanded laser beam cross section or laser beam pulses with a reduced laser beam cross section and said laser beam (2) has a homogeneous intensity distribution over the laser beam cross section. A stop (6) with a predetermined stop aperture geometry and a mask (7) with a predetermined mask aperture geometry are positioned in succession in the beam (2) path at the location. The device contains a field lens system (8) and an imaging lens (10), which are positioned in such a way that the non-diffracted and diffracted beam components of the laser beam (2) pulses transmitted by the stop (6) and the mask (7) are directed into the imaging lens (10) with a predetermined aperture with the aid of the field lens system (8) in such a way that a reduced image, ac curate in every detail and having a predetermined imaging ratio, of the intensity profile generated by the stop (6) and the mask (7) is generated over the laser beam cross section of the laser beam pulses in the imaging plane. In a beam guiding variant 1, an added lens system (16), the field lens system (8) and the imaging lens (10) are positioned relative to one another in such a way that a focus (19) is generated between the imaging lens (10) and the substrate surface and, in a beam guiding variant 2, the added lens system (16), the field lens system (8) and the imaging lens (10) are positioned relative to one another in such a way that a focus (22) is generated between the field lens system (8) and the imaging lens (10). At least one vacuum cuvette, which surrounds the region of the focus (19) and of the focus (22), is present.

摘要： A method for embossing optically diffracting microstructures in a thin foil, such as used to pack at least one of the list comprising food, chocolate, chewing gum, gifts, jewellery, clothes, tobacco products, pharmaceutical products, the embossing being produced with an embossing rollers set-up comprising at least one cylindrical embossing roller and a cambered counter roller. The method comprises confining the at least one cylindrical embossing roller and the cambered counter roller in a single roller stand of relatively small outer dimensions designed to withstand a pressure for the at least one cylindrical embossing roller and the cambered counter roller; using on a surface of a first one of the at least one cylindrical embossing rollers at least one raised embossing element adapted for microstructure embossing, whereby one of the at least one raised embossing elements comprises a platform distant at a height in a range between 5 m and 30 m above a surrounding surface of the first cylindrical embossing roller adjacent to it, and a pattern engraved on top of the platform (5), whereby the pattern comprises the optically diffracting microstructures with periodicity of gratings in the range smaller than 30 gm that produce from a diffuse or directed source of light in the visible wavelength range diffraction images with high contrast and high luminosity in a defined observation angle; and adjusting the pressure for the at least one cylindrical embossing roller on the thin foil in a range less than 80 bar relative to a platform area of approximately 100 mm2.

摘要： The embossing device for embossing packaging material comprises a set of embossing rollers with male die and female die rollers co-operating with one another, the surface of which is provided with texture elements, wherein the texture elements (M6R6) on the surface of the female die roller (M6), which are assigned to the texture elements (P6E6) on the surface of the male die roller (P6) are not inversely congruent by an amount of above 15 μm in axial and radial direction and the texture elements of the male die and female roller associated with one another comprise facets (F) for the purpose of local pressure elevation. A facet (F) comprises faces (FN), which with respect to the imaginary, continuous surface of the texture is inclined. With such facetted rollers, a very large variety of films can be embossed in an aesthetically appealing manner, wherein the films can be mainly employed in the tobacco and foodstuff industry.
