Summary:PCT No. PCT/EP97/02521 Sec. 371 Date Nov. 19, 1998 Sec. 102(e) Date Nov. 19, 1998 PCT Filed May 16, 1997 PCT Pub. No. WO97/45240 PCT Pub. Date Dec. 4, 1997A process and a device are described for the continuous production of block foam by the foaming of a mixture which reacts to form polyurethane and which contains carbon dioxide dissolved under pressure, wherein the pressure of the reactive mixture is reduced on passing through a pressure reduction zone in the form of an aperture, and blockage of the aperture is prevented by the relative movement of the aperture-delimiting faces with respect to each other.
