Abstract

A process for producing moulded articles from synthetic thermoplastic material, wherein the latter is plasticised by heating and compressing until it can flow in a highly plastic state, and is extruded in the form of a strip by extrusion through the nozzle, and wherein, for stabilising this strip, both its surfaces are brought into contact with thermally-conducting surfaces which are maintained at a predetermined temperature and both its surface zones are cooled and solidified until self-supporting, and, optionally after surface conditioning effected by heating the surface zone of the strip from within, the strip, thus stabilised, is subjected to thermal deformation to form the moulded articles, characterised in that during stabilisation at least one surface of the strip forced out through the extruder nozzle is passed over at least one roughened cooling surface, in the course of which it is brought into contact only with the peaks 22 formed by the roughness on these cooling surfaces. <IMAGE>
