<p>The invention relates to a method suited for the manufacture of air-cleaning filters, which includes the steps to feed out a rigid, although formable strip (8) in a lying state from a store (7), to advance a lying mat (24) of threads (3) transverse to the strip and connect one end of the thread mat to the strip (8), to give the strip (8) equipped with threads a generally wave-like profile shape, and to cut off an individual strip piece (8') from the continuous, thread-equipped strip in order to use this to finally form a thread-carrying filter body (2) in which the wave troughs and wave crests, respectively, of the profiled strip piece forms air-transmitting ducts in the body.</p> |
