  • Method and system for optically testing sawn timber for faults
    Patent number: 4827142
    Abstract: In a timber testing apparatus, use is made of an optical process, in which there is a linewise scanning of the timber surface at right angles to the longitudinal direction of the timber. If an optical detection apparatus (18) indicates a fault, the particular piece of timber is stored as being faulty at this point, so that continuous operation and detection of faults is possible in piece-related and position-related manner, so that suitable parts of the timber with a given, desired fault-free length can be rapidly determined.
