Warpscan measures the geometry of lumber in movement and reliably recognizes distortion of lumber such as twist, bow, spring, and cup in lineal or transverse transport direction. With highly accurate results independent of transport direction or irregular lumber movements during measurement, Warpscan addresses a widespread issue in the global wood processing industry, and is ideal for grading and separating defective lumber from warp-free products, especially for planer and glulam mills after the drying kiln.
