Apparatus for cooling extrusion press profile sections

An apparatus for cooling an extruded member comprising:

• a plurality of rollers for transporting the extruded member through said apparatus, said rollers defining a path for transporting the extruded member in a transport direction;
• a plurality of upper air nozzles for impinging cooling air on the extruded member from above the path of the extruded member, said upper air nozzles having a slit-shaped opening extending in a direction transverse to the transport direction of the extruded member, said slit-shaped opening having a first slit width, said upper air nozzles being disposed a first distance from the path of the extruded member;
• a plurality of lower air nozzles for impinging cooling air on the extruded member from below the path of the extruded member, said lower air nozzles having a slit-shaped opening extending in a direction transverse to the transport direction of the extruded member, said slit-shaped opening of said lower air nozzles having a second slit width, said second slit width being narrower than said first slit width, said lower air nozzles being disposed a second distance from the path of the extruded member, said second distance being shorter than said first distance, said lower air nozzles further being offset with respect to said upper air nozzles by approximately one-half of a pitch between said rollers measured in the transport direction;
• a source of cooling air connected to said upper air nozzles;
• and
• a source of cooling air connected to said lower air nozzles.
