<p>Sawing apparatus, comprising a frame with means for supporting on or against it a board for sawing, and first guide means which are designed for supporting and guiding in a first direction a coupling part on which are fixed second guide means intended for supporting and guiding a machine saw in a second direction crossing the first direction, so that the machine saw can be moved in a plane running parallel to the board. Extraction means have a suction nozzle provided at the front side of the board, for extracting particles of the board escaping during the sawing. An extraction channel is fixed at one end of the second guide means, running parallel to the second guide means and, after positioning, running behind the board, which channel is connected to an inlet of the extraction means and has an elongated opening running in the vicinity of a saw cut to be made in the second direction, for the extraction of particles released from the board at the rear side of the board at the saw cut. The supporting means have supporting elements which are designed for supporting the board, and which are movable by means of stop means of the extraction channel in a third direction crossing the board, in order to allow passage of the channel and the stop means. <IMAGE></p> |
