A plant for processing logs of which at least some are curved, comprises a processing station (3) including a cant-shaping device (41, 42) as well as at least one cutting device (43), e.g. a circular saw or a band saw, disposed after the cant-shaping device as seen in the feeding direction. The processing station comprises one or more sets of drivable feed rollers (24, 25) for feeding the logs therethrough. The feed rollers (24, 25) are laterally movable to follow a log with its curve oriented in a substantially horizontal plane without losing their driving engagement with the log. These rollers have means for maintaining the log curve oriented in the horizontal plane during feeding. A means (26) for finally guiding a front end of the log into the cant-shaping device is adapted, together with the feed rollers, to axially align the volume centre of the log with the centres of the cant-shaping device and the cutting device. Also, the cutting device (43) is adapted to make substantially vertical sectioning cuts in the cant. |
