Apparatus for cooling extruded sections

The extruded profile-cooling device (10) proposed has, located above and below the extruded profile output line, at right angles to the extruded profile output and transport direction (2), air nozzles (4, 5) with slit apertures. The air nozzles (5) under the extruded profile output line have a smaller aperture-slit width than the nozzles (4) above the output line which blow air on to the extruded profile (1) from above. The distance of the lower air nozzles (5) from the extruded profile (1) is smaller than the distance of the upper nozzles (4) from the extruded profile (1). The air nozzles (5) under the extruded profile are each staggered with respect to those (4) above the extruded profile by a half the distance between adjacent nozzles, measured in the extruded profile output and transport direction (2).
