ABSTRACT:
A filter element that includes a membrane which is to be detachably or non-detachably retained between fixed parts of a filter device, and which is provided on at least one of its sides with a permanently applied strip of sealing material. The strip projects relative to the surface of the membrane at that side, and extends over the entire length which is to be sealed. This sealing strip is thus a permanent part of the filter element. The sealing strip can be arranged directly at the rim portion of the membrane, and can at least partially encompass this rim. The provision of sealing strips so that they are opposite one another on both sides of the membrane is particularly advantageous. The sealing material can be applied in a flowable state, and can be subsequently cured to an elastomeric state. A particularly secure connection between the membrane and the sealing strip or strips may be achieved by penetration of the sealing material into the membrane.
