Patent number: 10245880Abstract: The invention relates to a press plate 1 or endless belt comprising a body with a stamping surface 2 and at least one external surface 4 which is provided not for stamping, wherein the press plate 1 or endless belt is equipped with an RFID transponder 6 which has a memory. A data record which identifies the press plate 1 or endless belt or use and/or manufacturing data of the press plate 1 or endless belt is stored in the memory. The acquisition of use and/or manufacturing data permits the storage of a precise history of a press plate 1 or endless belt and wireless transmission of this history to a receiver. On the basis of the use data, billing can be carried out which depends not only on the duration of use but also on the press strokes actually carried out.Type: GrantFiled: March 17, 2015Date of Patent: April 2, 2019Assignee: HUECK Rheinische GmbHInventor: Wolfgang Stoffel

Publication number: 20170197355Abstract: An embossing tool comprised of a pressing plate or endless belt that includes a structured surface, a first gloss level over the full area of the structured surface, and further, different gloss levels in several selected areas of the structured surface. The gloss levels are created by mechanical post-treatment and/or chemical post-treatment. A method for producing the embossing tool is also involved. The structured surface is provided with a first gloss level over the full area and receives further, different gloss levels in several selected areas in further work steps. The gloss levels are created via a mechanical post-treatment and/or chemical post-treatment.Type: ApplicationFiled: March 25, 2017Publication date: July 13, 2017Inventors: Wolfgang Stoffel, Martin Marxen

Patent number: 9561524Abstract: The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating and said surface having, in selected regions, at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions on the first coating, and be produced by a combination of metallic coatings and mechanical or chemical after-treatments. Therefore, for example, a wood pore with a defined structure can be substantially better reproduced, and the optical and haptic properties of the wood composite board produced using the press plates can thus be improved.Type: GrantFiled: August 14, 2015Date of Patent: February 7, 2017Assignee: Hueck Rheinische GmbHInventors: Martin Marxen, Wolfgang Stoffel

Publication number: 20160193866Abstract: The invention relates to a method for producing a surface structure on a pressing tool, in particular a pressing plate (1), endless belt or embossing roller. According to the invention, in order to avoid a lengthy etching process, the surface structure is produced by means of metal layers lying one over the other. For this purpose, at least a one-time application of a mask is performed in order to cover partial regions and at least a one-time application of a metal layer to the non-covered regions (5, 6) is performed in order to construct a surface structure composed of elevations. The two individual method steps are repeated until the desired structure depth has been reached. By means of a final treatment method, the surface can be rounded or provided with a hard chromium layer (7), for example.Type: ApplicationFiled: July 23, 2014Publication date: July 7, 2016Applicant: HUECK Rheinische GmbHInventors: Wolfgang STOFFEL, Martin MARXEN

Publication number: 20160144433Abstract: The invention relates to a method for producing a surface structure of a pressing tool, in particular a pressing plate or endless belt, for pressing material plates, plastic films, separating films, PVC surfaces and LVT (luxury vinyl tiles), check cards, passports, credit cards or plastic cards, comprising the following steps: providing and using digitized data of a 3-D topography of a surface structure, creating digitized data of individual 2-D layers of the 3-D topography, using the digitized data of the 2-D layers to guide a processing head and/or to position it in an x-y plane, or to move a work table in the plane spanned by an x-y coordinate system in relation to a stationary processing head, in order to connect a layer material to an existing carrier material or an already completed layer on the basis of the digitized data of the 2-D layers.Type: ApplicationFiled: June 16, 2014Publication date: May 26, 2016Applicant: HUECK Rheinische GmbHInventor: Wolfgang STOFFEL

Patent number: 9138774Abstract: The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating (6) and said surface having, in selected regions (7, 8, 9, 10, 11), at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions (7, 8, 9, 10, 11) on the first coating (6), and be produced by a combination of metallic coatings and mechanical or chemical after-treatments.

Publication number: 20150158330Abstract: The invention relates to a composite board (1) having at least one structured surface side, in particular a surface (2) with a wood pore, wherein elevated and lowered regions are formed. In order to obtain improved haptics and visual characteristics, it is provided that the embossing of the surface (2) takes place by way of a pressing plate or endless belt, which has a first gloss level over the full surface area and has been given further different gloss levels in a plurality of selected regions in further working steps, wherein the gloss levels can be produced by a metallic coating, a mechanical and/or chemical post-treatment.Type: ApplicationFiled: March 15, 2013Publication date: June 11, 2015Applicant: Hueck Rheinische GmbHInventors: Wolfgang Stoffel, Martin Marxen

Publication number: 20150064400Abstract: The invention relates to a method for producing a surface structure (4) of a workpiece (1) in the form of a pressed sheet, endless belt, or cylindrical embossing roller using at least one water-jet device with a machining head (25). The method according to the invention allows workpiece surfaces (2) to be machined in an environmentally friendly and inexpensive manner such that the 3D topography of a surface structure of a template or of the negative of the template is reproduced. The surface (2) of the workpiece (1) is partially removed using a water jet device in the method according to the invention. Using the pressed parts machined in this manner, different materials can be pressed for example, such as particle boards with support films, wherein the 3D topography of the surface structure is reproduced on the surface of the pressed material.Type: ApplicationFiled: June 24, 2013Publication date: March 5, 2015Inventor: Wolfgang Stoffel
