(54) Apparatus and method for continuously producing sintered metal fiber porous body


(57) An apparatus and a method are disclosed for continuously producing a sintered metal fiber porous body by pressing a metal fiber web (7) between a pair of rollers (1,2) and simultaneously sintering the metal fiber web, wherein the metal fibers of the web are not fused and they do not adhere to any surface of the rollers. The method of the invention includes the steps of pressing a metal fiber web between a pair of current-conductive rollers, the surface of at least one of the rollers being covered with graphite; and simultaneously providing a predetermined electric current between the rollers so that the current flows from one of the rollers to the other through the web.
