Abstract
Abstract A wood floor panel is disclosed comprising a plurality of substantially identical individual panel sections having bevels cut in their undersurface at the edges thereof such that when the sections are abutted together the bevel cuts of abutting sections form an adhesive well along which an adhesive bead is applied to fasten and hold the individual sections together. The panel may optionally be provided with tongues and grooves, each of which is cut along the entire length of a respective side edge thereof. Panels of various sizes can be formed using identical bevel cut panel sections which are merely arranged in the panel shape and size desired and fastened by the adhesive beads.
