ABSTRACT:
A metal microfilter foil is provided with a supporting structure made up of two layers which are deposited on a rear side of the foil. The first layer comprises a plurality of connecting elements of column or web shape which widen at the top to form enlarged portions which merge together to form the second layer leaving open macropores. The continuous supporting structure provides large pores as compared with the micropores of the foil and offer considerable stability.
