Abstract
Apparatus for cutting, swivel-bending and press-bending of sheet material includes a frame having a cross-beam, a member providing a bearing surface, and a clamping beam, the cross-beam having a snaker and the clamping beam having a bending die for press-bending. The frame supports the cross-beam and the clamping beam for movement relative to one another whereby the snaker and die may engage the sheet material to effect press-bending. The frame further supports the clamping beam and bearing surface for movement relative to one another to clamp the sheet material to effect cutting or swivel-bending thereof. A swivel beam and shearing beam are supported by the frame for movement relative to the clamped sheet material independently of movement of the clamping beam.
