摘要

In a cutting table for sheet metal and the like, the portion of the work that overhangs the table where it is cut is supported on a traveling adjustable support (9) having rollers on its upper surface. As the upper blade is brought down to cut the work progressively from the side near the pivot of the blade to the opposite side, a traveling carriage on which the traveling support is mounted is caused to move along the length of the cut so that it provides support to the work at the location where the blade is doing the cutting. The support is pivoted on an axis perpendicular to the cut so that it can adjust itself to the inclination of the upper cutting blade, the pivot being fixed on a vertically slidable member guided in the carriage. Hydraulically driven pistons enable the support to be raised or lowered with respect to the carriage. Wide cuts can thus be made without the strip that is cut off being twisted, coiled up, or otherwise deformed.
