Abstract
Machine for filling molding materials in molding boxes by compressed air, in which compressed air is projected axially and/or radially onto a sand column located in an internal support, characterized in that the support is made of porous material air-permeable of a porous plastic or ceramic sintered metal, the latter made particularly porous by means of gasifying agents or calcining material.
