Abstract: 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.

Abstract: 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.

Abstract: A method and device of embossing individually light-reflecting areas on a foil material, the method and device comprising feeding a foil material into a roller nip between a pair of rollers, wherein the pair of rollers comprises a first roller and a second roller, providing each of the first roller and second roller at their respective surfaces at least in a determined perimeter, respectively with a plurality of polyhedron-shaped positive projections and a plurality of negative projections complementary to the positive projections, whereby the plurality of positive projections are arranged according to a 2-dimensional grid. The plurality of polyhedron-shaped positive projections seamlessly and gaplessly join with those corresponding negative projections at the intended embossing of the foil material, hence enabling a homogeneously jointed embossed polyhedron-like shape in the foil. The method and device further comprise, for the purpose of providing a plurality of light-reflecting areas on the foil material, that are intended to reflect light in line with a table of reflectivity values for the 2-dimensional grid, according to an orientation and shape of each of the plurality of light-reflecting areas, and enabling a perception by the human eye of a user, of the intended reflected light on a determined wide viewing angle covered by reflected light from any of the light-reflecting areas, a step of adjusting for each of the plurality of light-reflecting areas to be provided, an orientation and shape of the corresponding positive projection in the 2-dimensional grid, that is intended to emboss the light-reflecting area.
