PCT No. PCT/EP91/01425 Sec. 371 Date Feb. 2, 1993 Sec. 102(e) Date Feb. 2, 1993 PCT Filed Jul. 30, 1991 PCT Pub. No. WO92/02316 PCT Pub. Date Feb. 20, 1992.An apparatus for cooling extruded profile sections comprises nozzles which are arranged above and below an exit path of the extruded profile section and which are formed as air nozzles arranged transversely of the pressing and exit direction of the extruded profile section and having slit-shaped nozzle openings. The air nozzles arranged beneath the exit path have a smaller nozzle slit width than the air nozzles arranged above the exit path and blowing onto the extruded profile section from above; the distance of the lower air nozzles from the extruded profile section is less than the distance of the upper air nozzles from the extruded profile section; and the air nozzles arranged beneath the extruded profile section are offset with respect to the air nozzles arranged above the extruded profile section in each case by half the pitch, measured in the pressing and transport direction of the extruded profile section.
