A method and an apparatus for continuously producing elongated siding panels is disclosed. The apparatus includes a conveyor, a plurality of mold plates, and a die for extruding a sheet of material onto the mold plates. The mold plates are formed of a rigid material and positioned adjacent one another and supported by the conveyor for forming the elongated siding panels. Each of the mold plates has an upper edge portion and a lower edge portion with an intermediate portion therebetween. The intermediate portion has an aesthetic pattern for imparting the pattern to the sheet of material with the adjacent mold plates having different aesthetic patterns. The lower edge portion has a lower leg extending substantially perpendicular from the intermediate portion defining a horizontal plane and a projection portion between the lower edge portion and the intermediate portion extends beyond the horizontal plane for imparting a jagged pattern to the intermediate portion.

What is claimed is: 1. An elongated siding panel formed of a sheet of material, said elongated siding panel comprising: an upper edge portion and a lower edge portion with an intermediate portion therebetween; said intermediate portion having an aesthetic pattern therein; said lower edge portion having a lower leg extending substantially perpendicular from said intermediate portion defining a horizontal plane and a cap leg extending upwardly from said horizontal plane such that said lower edge portion has a generally C-shape; and a projection portion between said lower edge portion and said intermediate portion extending downwardly beyond said horizontal plane, a jagged edge imparted by said projection portion to said intermediate portion. 2. An elongated siding panel as set forth in claim 1 wherein said projection portion angles upwardly at an angle of less than ninety degrees from said intermediate portion toward said lower leg. 3. An elongated siding panel as set forth in claim 2 wherein said projection portion is further defined as having a rounded nose. 4. An elongated siding panel as set forth in claim 1 wherein said projection portion extends a different amount beyond said horizontal plane to increase jaggedness. 5. An elongated siding panel as set forth in claim 1 wherein said lower edge portion is further defined as having an. aesthetic pattern thereon for imparting said pattern to the sheet of material. 6. An elongated siding panel as set forth in claim 1 wherein said upper edge portion defines a mounting flange having a locking groove for mating with said lower edge portion of a vertically overlapping panel. 7. An elongated siding panel as set forth in claim 1 further comprising an interlock having two corners with one of said corners having a substantially right angle for mating with said lower edge portion of a vertically overlapping panel.
