ABSTRACT:
To floatingly support a saw blade in a frame, the frame is formed, at its free ends, with forked elements; clamping elements are clamped to the saw. The engagement between the forked element (the blade fitting between the gap in the fork) and the clamping element is by means of a depression-projection fulcrum engagement, so that the clamping element, to which the saw blade is attached, can rock or tilt with respect to the forked element, attached to the frame, thus avoiding holding stresses on the saw blade which lead to breakage of the blade at the attachment or clamping points.
