Embodiment Construction

[0037] The single FIGURE shows a cross-section through an embossing roller 1 with an inner hollow space 10 , in which the hollow space is not shown in detail, but a negative pressure can be applied in a known manner. The embossing roll 1 is closed at the ends except for the line to a source of negative pressure (not shown). The hollow space 10 is surrounded by a cylindrically designed wall 11 in the illustrated embodiment, which comprises in total four discrete layers 111 successively succeeding one another by the hollow space 10 in the direction of the cylindrical outer surface 12 of the embossing roller 1 . , 112, 113, 114. All individual layers 111 , 112 , 113 , 114 are formed based on an epoxy resin mixture filled with a filler material and are each connected adjacent to each other.

[0038] The layers 111 , 112 , 113 , 114 can have the same or different layer thicknesses.

[0039] The outermost layer 11 adjacent to the outer surface has a structured outer surface 12 com...

Abstract

The invention relates to an embossing roller (1), comprising an inner hollow chamber (10), to which a vacuum can be applied, and a wall (11), which surrounds the hollow chamber (10) and which has a structured surface (12), which comprises elevations (120) and recesses (121) and which comprises pores that communicate with the inner hollow chamber (10), wherein the wall (11) comprises a plurality of discrete and successive layers (111, 112, 113, 114) following one another from the hollow chamber (10) in the direction of the surface (12) and wherein the individual layers (111, 112, 113, 114) are based on epoxy-resin mixtures filled with fillers and comprise capillaries that communicate with each other and cavities for forming the pores.

Description

technical field [0001] The invention relates to an embossing roll having an inner hollow cavity and a wall surrounding the hollow cavity and holes communicating with the inner hollow cavity, a negative pressure can be applied to the hollow cavity, the wall has a structured outer surface , the outer surface includes protrusions and depressions. Background technique [0002] Such embossing rollers are known and are used, for example, in the field of the production of structured substrates, for example artificial leather, with a surface imitating the natural grain of leather. The substrate is guided during or after its manufacture over the outer surface of the embossing roll and adheres to the structured outer surface or absorbs it by means of a negative pressure which can likewise be applied to the inner cavity (the negative pressure acts on the substrate through the holes). On it, the structured outer surface of the embossing roll is thus transferred in a counter-rotating ma...
