The objective of this research was to optimize the dimensions of machined tapers (bevels) at the edges of oriented strand board (OSB) to reduce the differential edge swelling (edge-flare) that causes problems when OSB is exposed to water. Machining an edge-taper, 0.6 mm-deep and 10 or 20 mm-wide eliminated edge-flare, but shallower tapers, 0.2 or 0.4 mm deep, were less effective. The combination of a 0.6 mm edge-taper and an effective edge-seal allows manufacturers of OSB to produce composite panels with reduced tendency to develop edge-flare, without having to modify the physical characteristics of panels or add additional adhesive or wax to the composite.
