An improved bending machine with three rollers which may be driven at different speeds and/or with differing torques. A control system receives signals indicative of the position and speed of rotation of one or more of the rollers. The control system is connected to a mechanism for adjusting the position, rotational speed and torque of at least one roller so that commands can be given to vary these parameters. Thus, the machine can be readily and accurately adjusted to produce bends of differing dimension in a strip workpiece.
