    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.

    摘要： The invention relates to corner shears for cutting out obtuse-angled to acute-angled corners from sheet metal by means of upper and lower knives (41, 40) which interact with one another in the manner of scissors and which, to form an angular cutting edge, each consists of two knives placed against one another in a V-shaped manner and supported on knife carriers (52, 53, 19,20) pivotable about a vertical axis A, the pivot axis (A) passing respectively through the cutting corner and means being provided for adjusting the angle .alpha. between the cutting edges, each upper-knife carrier (52, 53) being connected positively, without the shear stroke being impeded, to the corresponding lower-knife carrier (19, 20) via an engagement piece (72) fastened to the upper-knife or lower-knife carrier.

    摘要： Method of and apparatus for manufacturing a plurality of continuous serrated metal strips from a single strip of feed stock includes means for advancing the single strip of feed stock into a shear means. Exertion of a cutting force by a ram acting upon dies of the shear means causes shearing of the feed stock to form a plurality of serrated metal strips. Strip positioning means disposed on the discharge side of the shear means cooperating with hold-down means and frictional forces generated between the cut strips and the dies preclude deformation of the metal strips in a coil-like manner as has been heretofore known. Any kinks formed in the apparatus during shearing may be removed by a kink-removal device.
