Abstract

The sheet folding machine consists of a bed plate (2) and a pressure plate (3) between which the workpiece is clamped. The clamping force is provided by the cylinder (8). The folding is executed by the blade (4), itself driven by a cylinder (15). During this process the bed plate and pressure plate are locked in position by the clamps (11, 14), which after the operation can be released by the cylinder (13) to allow the workpiece to be released by allowing the pressure plate to swing up.
