ABSTRACT:
An improved method for fabricating trailer length platform flooring from wooden blanks comprises selecting kiln dried lumber having a predetermined width and thickness and exhibiting preestablished strength and durability characteristics. The lumber is inspected for the presence of unacceptable defects and the defects are cut out to form defect-free blanks of varying lengths. The blanks are aligned successively in spaced end to end relationship with the trailing end of one blank facing the leading end of the next successive blank. The facing ends are then machined with interlockable vertically extending fingers, adhesive is applied to at least one of the ends, and the fingers are pressed together with a predetermined pressure to bond the ends of the blanks together. These steps are repeated resulting in a continuously growing composite plank comprised of end-to-end joined blanks. When the composite plank has reached a predetermined length, it is cut to a prescribed length, cured, proof loaded to test its strength, milled to a predetermined exterior configuration, and bundled in kits for flooring platform trailers. The resulting trailer length finger jointed trailer flooring planks are far superior to flooring of the prior art.
