  • Patent number: 4545754
    Abstract: An apparatus for producing moldings (48) from concrete et cetera, particularly concrete paving stones, the top side of which exhibits partial surfaces of different vertical level, comprises a molding table (46), a molding frame (30, 31) and a stamp fitting in the latter. For better consolidation and in order to facilitate clean removal from the mold, it is provided that the stamp consists of two separate partial stamps (33, 42) guided in each other, the end cross-sectional surfaces of which are dimensioned so that the one (33) molds the lower-lying and the other (42) the higher-lying top partial surfaces of the molding (48) and that the stroke distance of the partial stamp (42) for the higher-lying partial surfaces is limited in an upper consolidation position, in which both partial stamps conjointly reproduce the top side of the molding, and in a lower mold-removal position, by stops.
