Abstract
The invention pertains to a device for processing printed matter, in particular, for punching, perforating, grooving, embossing, imprinting, spot-coating or the like. In order to simplify the attachment of the processing tools required for the additional processing, the invention proposes that a carrier be attached to a rotating or flat working element 8. The processing tools can be attached to this carrier such that they can be easily removed again. The size of the processing tools 3 that, for example, are provided with punching lines 4 can be limited to the processing area. The processing tools can be removed and also easily repositioned at any time. A magnetic attachment proved particularly advantageous. For this purpose, the carrier may be realized in the form of a magnetic foil 6.
Claims23
Device for punching, grooving, perforating, embossing, imprinting and coating paper materials and the like, with a roller-shaped cylinder, on the periphery of which at least one processing tool is arranged, wherein the processing tool contains a working surface that extends [text missing in original] an additional cylinder that is arranged opposite of and assigned to the above-mentioned cylinder, and wherein the working surface is arranged flat or [text missing in original], characterized by the fact that the processing tool (3) is adhesively and separably fixed on the cylinder (1).
Device for punching, grooving, perforating or embossing paper materials and the like, with a flat working element, on the flat working surface of which at least one processing tool is arranged, wherein the processing tool contains a working surface that is arranged opposite to another flat working surface, characterized by the fact that the processing tool (3) is adhesively and separably fixed on the flat working surface of the working element.
Device for punching, grooving, perforating or embossing paper materials and the like, with a flat working element, on the cylindrical working surface of which at least one processing tool is arranged, wherein the processing tool contains a working surface that is arranged opposite to a flat working surface, characterized by the fact that the processing tool (3) is adhesively and separably fixed on the cylindrical working surface of the working element.
Device for punching, grooving, perforating or embossing paper materials and the like, with a flat working element, on the flat working surface of which at least one processing tool is arranged, wherein the processing tool contains a working surface that is arranged opposite to a cylindrical working surface, characterized by the fact that the processing tool (3) is adhesively and separably fixed on the flat working surface of the working element.
Device according to one of the preceding claims, characterized by the fact that the processing tool consists of a punching, perforating, groove-forming or embossing tool of ferromagnetic material.
Device according to one of the preceding claims, characterized by the fact that the processing tool consists of a tool that is realized similarly to a printing plate and serves for producing an imprint or for applying a localized coating, and by the fact that the rear side of the tool contains a layer consisting of a ferromagnetic material.
