In a process in roller folding a folding roller (4) is moved against a workpiece (12). The urging force of the folding roller (4) against the workpiece (12) is resilient, and the folding roller (4) moves in a path alon g the workpiece (12) by means of a movement device provided with a control system. The urging force is sensed by a sensor, which is integral in or included in the movement device, and the output signal of the sensor is fed to the control system. |
