ABSTRACT:
Apparatus for cutting sheet-like material, such as metal, comprising a frame (1), a table (2) for supporting the material plate to be cut, a fixed lower knife (3), an upper knife (4) movable up-and-down and cooperating with the lower knife, said upper knife including a cutting angle with the lower knife. The apparatus further comprises an adjustable stop (6) for determining the width of the material strip to be cut and a plurality of support arms (10) distributed along the length of the apparatus for lifting the fed part of the material plate, the support arms extending transverse to the lower knife and being adjacent to the lower knife with one end, the other end of each support arm being pivotably supported on a supporting beam (12). For each support arm a pressure spring (13) is provided, said support arms during a cutting action each being pivotably downwards by the upper knife against the action of the corresponding pressure spring, while clamping the material strip to be cut.
