Abstract: A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.

Abstract: The clamping device has a stationary, substantially vertical clamping face (5) for the workpiece, arranged at right angles with respect to the feed direction of the saw band. A movable clamping jaw (8) is horizontally movable with respect thereto, the clamping jaw (8) having a substantially vertical clamping face (9). The movable clamping jaw (8) is formed as a clamping bridge (7), reaching over the machine table. The fixed clamping face (5) also reaches over the machine table, while leaving a passage for the saw band. The ends of the clamping bridge are guided horizontally beside the machine bench, for clampable adjustment perpendicular to the clamping faces (5, 9), the clamping bridge (7) being pivotable on guide blocks (22, 23) slidable on guide rails next to and below the table (2) of the saw, so that the clamping bridge can clamp a workpiece (3) between the clamping faces, by a toggle connection to a handle, or release the movable bridge.
