Abstract
A method of applying a protective strip to an edge of a wood product piece. The process uses a set of aligned rollers and a belt apparatus that includes a pair of rollers having a shoe positioned between them and a belt fitted about the rollers and the shoe. The distance from the belt to the first set of aligned rollers is substantially equal to the width of the wood product piece. The wood product piece is placed between the first set of aligned rollers and the belt apparatus and resin is applied to the edge the wood product piece. The wood products piece is then squeezed between the first set of aligned rollers and the belt apparatus. At least a subset of the rollers are driven to move the wood products piece along the belt apparatus, thereby causing the resin to be squeezed into the edge of the wood products piece. Finally, the resin is cured.
