A sintered metal fiber medium as subject of the invention comprising at least one pleat, which pleat comprising a first leg being present according to a first plane, and a second leg being present according to a second plane. The first plane and the second plane intersect along an intersecting line according to a dihedral angle theta. The pleat comprises a bending part for coupling the first and the second leg. The medium has an average thickness at the legs of TI. A sintered metal fiber medium as subject of the invention is characterized in that the bending part comprises at least one distinct linear zones, which is substantially parallel to the intersecting line, in which linear zone, the medium has a minimum thickness Tb, which Tb is smaller than TI. In the linear zone or zones of the bending part, the thickness of the medium is reduced, so Tb is less than 0.5 times TI. Further, a method to provide such pleated sintered metal fiber medium is described. |
