ABSTRACT:
A method and apparatus for forming a skid-resistant surface on a thermoformed object such as a bed liner. The method includes forming a blank of extruded plastic material, abrading the surface with a wire brush, reheating the blank and thermoforming the blank to open the abraded surface of the blank. The apparatus includes an extruder delivery mechanism delivering a blank of sheet material to a wire brush which is turned by an electric motor at a speed slightly greater and in the same direction as the travel of the blank under the roller.
