摘要： An embossing method allowing to emboss a material on both sides comprises feeding the foil material into a roll nip between a pair of a first roll and a second roll, providing the first roll and the second roll each with a plurality of positive projections and a plurality of negative projections of identical shaped polyhedral structures, a first subset of the plurality of positive projections being disposed with a first periodicity on a first grid in axial direction and a second periodicity on the first grid in circumferential direction on the first roll, and a second subset of the plurality of negative projections being disposed with the first periodicity in axial direction and the second periodicity in circumferential direction on the first grid intertwined with the positive projections, in axial and circumferential directions respectively, and projections complementary to the first grid, on the second roll, each of the positive projections and the negative projections on the first roll during operation of the rolls and in the roll nip being surrounded on all sides by positive projections and negative projections on the second roll, the positive projections of the first roll together with alternating corresponding negative projections on the second roll forming during the operation of the rolls and in the roll nip, a first straight line substantially parallel to the axial direction, and the negative projections of the first roll together with alternating corresponding positive projections on the second roll forming during the operation of the rolls and in the roll nip, a second straight line substantially parallel to the axial direction. The positive projections and the negative projections are such that in the axial direction on the first roll each positive projection shares a lateral base border with at least one negative projection adjacent to the positive projection, and during the operation of the rolls and in the roll nip, all lateral oblique surfaces of the positive and negative projections of the first roll are just above the surface in full faced view with the corresponding lateral oblique surfaces of the respective negative and positive projections of the second roll, thereby enabling a homogeneous distribution of pressure to the material.

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： 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： In the method for applying identification features to a packing strip in order to authenticate the processed packing, the packing strip is fed in a packing line to an embossing station, where logos of all kinds and/or codes and/or a satin finish and/or fold lines are embossed at the cycle rate of the packing machine by means of embossing rollers by deforming the packing strip, Identification: features and possibly other features are produced additionally on the packing strip on-line, in the same process step, and synchronously to the cycle rate by material removal by means of a feature setup comprising a laser installation, the packing strip having a thickness of 50 μm to 300 μm. The thus treated packing strip is subsequently further processed. Due to the fact that the feature setup for producing the identification features is provided in addition to the embossing rollers but operates in the same process step, all known embossing rollers can be used, and due to the application of lasers for producing the features, e.g. a consecutive numbering can be produced, thereby ensuring a secure authentication method without the need of changing substantially the embossing station comprising a housing with at least two embossing rolls, or lowering the processing speed.
