ABSTRACT:
A plurality of molding boxes having a common center line are disposed in an aligned manner in a horizontal guideway located, in the direction in which pressure is exerted and expulsion is effected, between a pressure piston and an outwardly pivotable pressing device and the molding devices are displaceable in the guideway. One pattern carrier plate is provided between each of the individual molding boxes, and the pattern carrier plates can be moved in and out when the molding boxes are apart. A tilting device is disposed at the outlet of the machine, which selectively either allows pressed mold bodies to pass by it with the position of their seams unchanged, or tilts the mold bodies, pressed in pairs, by an angle of 90.degree..
