Abstract

1. A process for compressing granular moulding material such as foundry moulding sand by means of a pressure wave of gaseous medium such as compressed air acting at high speed on the surface of the loose moulding material, with the compression medium emerging uniformly form Laval-type nozzles that are arraged close together in a raster system in a bottom plate (54) over the entire surface of the moulding material (50), characterized in that the single air jets burst open at the nozzle outlet so that the air jets emerging close to each other intermingle and impinge vertically as well as uniformly at all points as a pressure wave on the surface (50) of the loose moulding material.
