4.1 Pressure (bending force) acting on the roller of the plate bending machine. The pressure on the roller can be calculated based on the moment needed for bending the steel plate. In this case, the steel plate is considered a beam under a concentrated load. The load is the pressure exerted by each roller on the steel plate, as …
