摘要： A method that includes moving a sheet material between first and second groups of rolls following a winding path according to a setpoint speed, driving the first group of rolls by a first drive, driving the second group by a second drive independent of the first drive, measuring the speed of the first drive, measuring the speed of the second drive controlling the speed of the first drive by means of a first torque setpoint signal which is a function of a first error signal obtained from the difference between the setpoint speed and the speed of the first drive, and controlling the speed of the second drive by means of a second torque setpoint signal which is a function of a second error signal obtained from the difference between the setpoint speed and the speed of the second drive, and is also a function of an additional torque gain.
