ABSTRACT:
An extrusion apparatus includes a slot-type cooling table over which elongated extruded members move laterally. A plurality of side-by-side blower units are located beneath the table to develop a blanket of air through which the aluminum extruded members pass. Each unit includes a motor-driven tubular air blower having a tubular outlet duct. A rectangular discharge nozzle is connected to the air blower and spans the extrusion line and also extends along a predetermined length of the extrusion conveyor. A plurality of adjustable louvers are connected within the nozzle to uniformly disperse the air from the tubular outlet duct into a square uniform curtain of air which passes upwardly over the conveying line and the metal extruded member on the conveyor. The louvers direct the air directly perpendicular to the extrusion and/or partially on-line with the hot extrusion. This produces high quality, uniform characteristic in the aluminum extruded member.
