In a method for positioning logs in connection with the shaping of cants in a cant-shaping device (1), the individual log (3) is fed in its longitudinal direction through a turning device (2) serving to rotate the log, when continuously fed, to a rotational position which later gives an optimum yield of wood. The curved shape of the log is optically read by reading equipment (21, 22), and data on the log shape recorded by this equipment is processed in a picture-processing device or computer. The latter is made to transmit control pulses to the turning device (2) so that this device, after receiving the front end of the log, is capable of rotating the log not only through the angle of rotation required to enable a complete reading of the log shape, but also through the angle of rotation required to rotate the log to the optimum rotational position before the rear end of the log leaves the turning device. |
