Abstract

A method for manufacturing a porous laminate includes continuously passing a laminate preform having a metal wire mesh and a metal non-woven fiber web superposed on the wire mesh between rotating pressure rollers having differing electrical potentials. The fibers of the non-woven web are sintered together at mutual points of contact and to the mesh by passing an electrical current cross-sectionally through the laminate preform in a zone of contact with the rollers, thereby forming the porous laminate.
