COMPOSITE WOOD CONSTRUCTION MEMBERS HAVING A TEXTURED SURFACE AND APPARATUS AND METHOD FOR PRODUCING SAME

摘要

A member made from a composite wood material has an elongated body having at least one outer surface and opposed side edges and a plurality of grooves formed on the outer surface. An apparatus for forming a textured surface on a member comprises a frame, a tool bit driving mechanism supported by the frame and a tool holder connected for lateral movement to the driving mechanism and adapted to be supported over a surface of the member. At least one tool bit is mounted to the tool holder. The driving mechanism moves the tool holder such that the tool bit forms grooves on the surface of the member as the member moves past the apparatus. A method of forming a friction-enhanced surface on a member includes forming longitudinal ridges on a surface of a composite or plastic building member, and forming lateral grooves on the surface of the member with the apparatus.
