Abstract
An inline edge-sealing apparatus and method for sealing the kerf surfaces of cut cellular PVC board includes a rotary saw with either a tandem sealing disc or with an integral elevated sealing surface that is dimensioned to provide precise interference with kerf surfaces for friction and heat to melt and seal the surfaces in an aesthetically desirable manner. A kerf splitter, such as a kerf splitting pin, rod or riving knife, may be provided following a saw blade with integral kerf-engaging surface to avoid disruption of the sealed surface when cut boards exit the saw blade teeth.
