Method for producing tables on Planks and other Sierra maderajes Cut from one piece of work logs and logs of similar type and a device for carrying out the method

摘要

The sawing of an elongated workpiece, such as a log or cant, is effected by feeding the workpiece longitudinally through a saw; sensing the longitudinal configuration of a longitudinal side surface of the workpiece on one side only of the workpiece as the latter passes through the saw; and orientating the workpiece relative to the saw in accordance with the sensed configuration to saw the workpiece longitudinally substantially parallel to the sensed configuration. For the sawing of a crooked workpiece, the configuration of a longitudinally extending concave side surface is sensed and the workpiece is sawn "round the curve" substantially parallel to the sensed concave configuration.
