Abstract (en)

[origin: EP2905246A1] The method is applicable to a rewinding station comprising a first mandrel (1) and a second mandrel (2) associated with respective first and second motors for rotating in the same direction so that a web (L) wound around the first mandrel (1) is unwound from same and rewound on the second mandrel (2) with an amount of tension that can be adjusted by the adjustment method which comprises controlling the speed of the second motor. Said method is a sensor-less open-loop adjustment method and comprises performing speed control on the second motor with rotational torque limited to calculated values. The adjustment system, the computer program and the machine are suitable for implementing the method of the invention.
