A method of producing a deforming tool (2) having a structured embossing surface (4) which can be brought into contact with a surface of a substrate (1) for plastic deformation thereof (of the substrate), the method comprising: determining a target structure to be produced on the substrate (1); geometrically distorting the target structure, such that an “embossing image structure” is obtained; inverting the “embossing image structure”, such that the embossing structure for the embossed surface (4) is obtained; and producing the embossing surface (4) of the deforming tool (2) according to the embossing structure.

A formed sheet metal material (100) and methods, tools (1, 2, 8) and apparatus for forming the sheet metal material (100) in which a pattern of projections and depressions are cold worked in a first portion (101) and, simultaneously, indicia (103) is embossed in a second portion (102) of the sheet material (100). The cold worked portion (101) is formed with the projections and depression configured and distributed such that lines drawn on a surface of the formed sheet material (100) between adjacent rows of projections and depressions are not rectilinear. The indicia (103) is indicative of the alignment between the tools (1, 2, 8).

The invention relates to a method including very superficial embossing combined with superficial laminating, which involves a slight reduction in thickness, the method being applied to plates several millimetres thick and to aluminium sheets having a thickness of less than 0.3 mm, supplied, in either case, as independent plates or in a continuous roll.

Provided is a method for producing a multilayer, surface-structured panel, in particular a multilayer, surface-structured flooring panel. The method includes the steps of: providing at least one plastic carrier panel, in particular in the form of a continuous strand; introducing surface structures on at least one side of the plastic carrier panel by means of embossing; applying at least one primer to the structured surface of the plastic carrier panel; printing the plastic carrier panel by direct printing to form a decorative layer; applying an anti-wear layer containing abrasion-resistant particles; applying at least one lacquer layer; and curing the layer structure.

A method for manufacturing a product having a surface provided with embossments, includes bringing a material web is in contact with a roller. The roller is provided with a relief at its surface, with which, via this relief, embossments are formed in the material web. The roller has a circumference of which, or at least certain parts thereof that are variable, or alternatively the circumference of the roller is variable by making use of embossing elements, wherein the mutual angular position thereof is adjustable.

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.
