ABSTRACT:
A method for producing an extrusion having a wood grain appearance. A first extruder including a die and a second extruder which includes a housing and a screw is provided, the screw having a portion disposed within the housing and a portion projecting outwardly from the housing. The second extruder is secured to the die of the first extruder by a pipe, the pipe receiving the outwardly projecting portion of the second extruder screw. A first material is extruded through the first extruder die to produce an extrusion and a second material is introduced into the second extruder. The second material is delivered through the second extruder and the pipe means to bond the second material to at least a portion of the surface of the extrusion to provide an extrusion with at least a portion of its surface having a wood grain appearance. An associated second extruder as well as an apparatus for producing an extrusion having a wood grain appearance is also provided.
