Abstract
The invention relates to a method of manufacturing a filter which includes a number of ducts formed by a number of deformable foils. The foils have electrically insulating outer sides, with electrically conductive bands which are separated from one another by electrically insulating bands. The electrically conductive bands on a first outer side of the foil are arranged so as to be offset relative to the electrically conductive bands on the second outer side of the foil. The foils are stacked. The oppositely situated electrically insulating bands of the oppositely situated foils are interconnected. The foils are ultimately moved away from one another in a direction transversely of the foils in order to form the ducts between the interconnected foils. At least one detached, electrically insulating section is situated in a prolongation of at least one electrically conductive band and is not connected to an oppositely situated foil.
