Apparatus for providing uniform gradient cooling simultaneously on all sides of an extrudable material to maintain the physical properties uniformly throughout the material, comprising: means for extruding the material, foraminous means for conveying the extruded material, bisurfacially cooling means for directing a cooling medium simultaneously against the sides of the extruded material, and temperature-gradient control means operatively connected to said bisurfacial cooling means for selectively varying the temperature of the cooling medium to provide continuous gradient cooling on all sides of the material to maintain its physical properties uniformly throughout. A method for providing uniform gradient cooling simultaneously on all sides of an extrudable material to maintain the physical properties uniformly through the material, comprising the steps of: extruding the material, providing a foraminous support member, conveying the extruded material on the foraminous support member, bisurfacially cooling the material by directing a cooling medium simultaneously against the sides of the extruded material, and uniformly varying the temperature of the cooling medium to provide continuous gradient cooling on all sides of the material to maintain its physical properties uniformly thereout.
