Definitions
- the present invention relates to a filter element having the features of the preamble of claim 1 and a method and an apparatus for producing such filter elements.
- the spacer elements of the functional structure cause the filter element, that the adjacent in the circumferential direction wrinkles can not create a flat against each other, but are supported on the spacer elements together.
- the existing between adjacent in the circumferential direction wrinkles filter surface remains effective, whereby the operability of the filter element is improved.
- Filter elements of this type which can be configured, for example, as ring filter elements or as plate filter elements, exist in virtually any dimensions.
- the respective functional structure For this purpose, it is necessary to adapt the respective functional structure to the respective dimensions in order to be able to ensure the respective function.
- the spacer elements are connected to the respective To adjust wrinkle height to prevent positioning of spacers in the region of a fold edge.
- different embossing rollers with different functional embossing structures must also be provided in order to be able to produce the filter material for the various filter element types.
- the production of the filter material for different filter element types can in principle be carried out with the same device, for which only the respective embossing roller must be replaced.
- there is a correspondingly large space requirement In order to be able to store a corresponding number of embossing rollers for a large number of different filter element types, there is a correspondingly large space requirement.
- the functional embossing structure is incorporated in a conventional manner directly into the outer circumference of the embossing roll. This is usually done by means of machining, in particular by turning processes and milling processes. Especially in turning processes, the possibility for shaping the functional structure, in particular for the spacer elements, is severely limited. In particular, by rotation processes on the embossing roll only annular elevations or recesses which are closed in the circumferential direction can be produced, which can be virtually arbitrarily segmented with the aid of milling processes parallel to the longitudinal central axis of the embossing cylinder.
- the present invention is concerned with the problem of providing an improved embodiment for a device or for a method of the type mentioned above, which is characterized in that a variant formation for the filter elements with reduced effort is possible. Furthermore, a way is to be shown to increase the variety of possible geometries for the spacers or for the functional structures.
- the present invention also deals with the problem of providing a filter element of the type mentioned above, an improved embodiment, which is characterized by an improved use of the embossed structures.
- the invention is based on the general idea of equipping at least one fold in addition to the functional structure with an embossed information structure which haptically represents at least one product and / or manufacturer information, which is preferably also visually perceptible.
- an embossed information structure which haptically represents at least one product and / or manufacturer information, which is preferably also visually perceptible.
- Such a three-dimensional information structure differs from the usual functional structure, which does not represent information about the product or the manufacturer.
- elements of the information structure may also serve as spacers, but need not.
- Typical information structures are, for example, characters, pictures, pictograms. In particular, a trademark of the manufacturer can form such an information structure.
- the information structure can also be designed in the manner of a bar code or dot code with the aid of dashes or dots.
- the information structure in the manner of the Braille script can also be designed by means of dots.
- a type number for the respective product, that is to say for the respective filter element, in the form of such an embossed information structure can be represented directly at the respective fold, eg as letter and / or number. combination of numbers.
- characters are to be understood as meaning “typical” characters of "living" languages.
- the embossed three-dimensional functional structures have a significantly simpler structure.
- Such functional structures usually have only straight webs or ribs or punctiform nubs. Querfalze extending transversely to the longitudinal direction of the filter material can define folding edges to simplify the pleating or folding of the filter material. At the same time, the folded edges are stabilized thereby.
- the geometrically simple spacer elements for example in the form of ribs and / or studs.
- the function structure differs from the information structure, in particular haptically and / or optically.
- the spacer elements can be configured as a stabilization or stiffening structure, which prevent or at least hinder a deformation of the filter material by the pressure applied during the filtration operation.

- At least one fold has only the functional structure, while at least one other fold has only the information structure.
- the filter element is preferably a plate filter element with a preferably flat filter body or a ring filter element with an annular filter body.
- a plate filter element may be injection molded or foamed in the usual manner, which is suitably arranged laterally closed circumferentially on the filter body.
- a ring filter element may in the usual way have two end disks, which are arranged on the axial end faces of the annular filter body.
- the end plates can be molded, foamed or glued, welded or anplast melt.
- the present invention is based on the general idea, with regard to the device or method, of forming the functional embossing structure not directly on the embossing roll, but on an embossing plate, which represents a separate component with respect to the embossing roll and which can be fastened on the outer circumference of the embossing roll.
- This makes it possible to use the same embossing roller with different embossing plates for producing filter material for different filter element types.
- the cost of producing such different embossing plates is significantly less than the cost of producing different embossing rollers.
- the respective Rolls themselves have a un structured or smooth outer skin on which the embossing plate is placed.
- the respective embossing plate can be made of a flexurally elastic material, so that it can be bent elastically into the cylindrical shape of the embossing roller for attachment to the embossing roller, while it is flat in the unbent state.

- the introduction of the respective embossing structure into the embossing plate is simplified when the embossing plate is aligned.
- etching processes can also be used in order to produce the respective embossed structure. Also simplifies a milling process, since virtually only a two-dimensional milling is required to form the respective embossing pattern in the flat stamping plate.
- the embossing plate may be secured by magnetic force to the embossing roller.
- the embossing plate is particularly easy to attach to the embossing roller and solve it, whereby a rapid change of the embossing plate is simplified.
- the embossing plate may at least partially consist of a ferromagnetic material, while the embossing roller consists at least on its outer periphery of a magnetic material.

- an information onsgarge founded which is configured negatively to an information structure and the at least one folding and at least one producer and / or product information optically and / or haptically recognizable impressed into the filter material.
- the manufacturing method is expediently carried out in such a way that the filter material is folded only after impressing the functional structure and the information structure, for which purpose the device is provided with a corresponding pleating station for folding the filter material provided with the embossing.
- the pleating station is then arranged with respect to the direction of movement of the filter material within the device behind an embossing station in which the embossing roller is located.
