The invention relates to a method for producing a contoured filter element, according to which method at least one filtering medium is applied to a flat backing material and is detachably secured thereto. The filtering medium is cut out on the backing material to form the contoured filter element and said contoured filter element can be detached from the backing material for use. The invention also relates to a filter element arrangement produced by means of this method.

Method for producing a contoured filter element and filter element arrangement

A filter element with a filter medium and at least one retainer, to which the filter medium is fixed. The retainer comprises a retainer base body and a retainer attachment. The filter medium is arranged between the retainer base body and the retainer attachment at least in sections, and at least one profile element is formed on the retainer base body and/or on the retainer attachment to allow form-fitting and/or force-fitting retention of the filter medium there between.

The invention relates to a fastening element for two-dimensional fiber material comprising a basic element and pin-shaped profile elements, which protrude from the basic element in order to penetrate the fiber material. Provision is made for the profile elements to be deformable in order to form retaining heads for the fiber material. The invention further relates to a method for fastening two-dimensional fiber material which can be carried out with a fastening element of such type. By the method in accordance with the invention a cold micro-riveting can be achieved.
