<p>Apparatus for shaping wood comprises a carriage (2) having a front pair of wheels (3) and a rear pair of wheels (4), the carriage mounting a saw blade (1 ) and a saw motor for driving the saw blade to perform a sawing action trans- versely of the carriage. The front pair of wheels (3) is arranged to run on a first pair of guide rails (5) and the rear pair of wheels (4) is arranged to run on a second set of guide rails (6) extending parallel to the first set of guide rails. A bed for receiving the wood to be cut is located between the rails. The first and second guide rails (5 and 6) are formed with a vertically varying profile whose shape is determined by the cut shape of the wood it is desired to achieve, the profiles of the first set of guide rails being displaced horizontally with respect to the profiles of the second set of guide rails by a distance corresponding to the distance between the axes of rotation of the front and rear wheels. Drive means are provided to propel the carriage along the rails to follow the vertically varying profile.</p> |
