Filed: 1980-02-11
Abstract: In a board-trimming and board-dividing saw (1) with a sawing unit movable along the machine table (5), work rests (7, 8, 9, 10; 11, 12) arranged on both sides of the machine table (5), and a width stop (13') displaceable at right angles to the cutting plane (E) and running parallel to the cutting plane (E), it is difficult to remove manually the remnant which is obtained when separating the size cuts, rests on the side of the width stop (13') and has to be taken to a cutting-to-length stop (18) by the operator (19). This is because these remnants lie on the other side of the cutting plane (E) of the sawing unit, and in fact on a smooth base from which they cannot be easily removed. In order to facilitate this removal, the work rest (7) allocated to the last stop (18) and lying on the side of the width stop (13') is mounted in such a way that it can be raised in its area adjacent to the machine table (5). Consequently, the remnant can be lifted slightly from the base and can easily be taken hold of by the operator (19). <IMAGE>
