Abstract
A filter which includes a stack of deformable foils which are locally attached to one another, and also includes comparatively rigid members which are situated to both sides of the stack of foils, extend parallel to the surface of the foils and each of which is attached to an outer surface of the stack of foils by way of a buffer member. The foils can be moved away from one another in a main direction by means of the rigid members, which main direction extends transversely of the surface, in order to form ducts between the foils. The buffer member is then contractible mainly in a direction which extends parallel to the surface and transversely of the ducts.
