Abstract
A filter element has a mat-type or sheet-type filter web () forming by its outside () at least in part a filter jacket (). Along the outside () of the filter jacket (), a surface configuration or modification takes place with structures () being delimited from the remaining surface () of the filter web (), being joined to the filter jacket () and being of presettable contour and/or thickness. The structures () are generated by spray-fiber application and shaping, in such a manner that in time sequence, first the structures () and then the filter jacket (), or in reverse order in time sequence, first the filter jacket () and then the structures (), or that simultaneously both the filter jacket () and the structures () are formed in negative or positive shape on the filter jacket (). The production of the filter element and a shaping device used in this production process are disclosed.
