Abstract
An apparatus for compacting granular molding material, particularly foundry molding material, includes a filling unit, a compression unit and a molding unit. A sealing surface on the molding unit is engaged by depending sealing strips on the compression unit to provide a tight seal. The opposed sealing strips extending parallel to molding unit movement have force-transmitting sealing elements, while the other pair of opposed sealing strips extending perpendicular to the molding unit movement repel molding material from the sealing surface.
