  • the tension of the web 4 is automatically controlled with higher precision, and/or with higher accuracy and/or with higher speed.
  • the machine 1 is configured so that the higher the tension, the higher the resistance parameter Z, and so that the lower the tension, the lower the resistance parameter Z. Therefore, the machine 1 is configured so that the resistance parameter Z is directly proportional to the tension.
  • the resistance parameter Z is indicative of a force or torque acting on the buffer motor BM. In this way it is increased the accuracy of controlling the tension as the resistance parameter Z, which is detected for controlling the tension, is strictly correlated with the same component, that is the buffer motor BM, which is used also for controlling the position Y, which position Y is another variable used for adjusting the tension together with the detected resistance parameter Z.
  • a variation of the feeding device parameter K produces an effect or disturbance on the buffer motor BM.
  • This effect or disturbance is represented by letter w in Figure 3 . Therefore also the position Y can be influenced by a variation of the feeding device parameter K.
  • Controlling the tension is carried out based at least on a first threshold Z 1 and a second threshold Z 2 .

  • the example flow diagram of Figure 4 is preferably referred to a situation in which the second threshold Z 2 is greater than the first threshold Z 1 . However, the example flow diagram of Figure 4 can be considered applicable also to a situation in which the first threshold Z 1 and the second threshold Z 2 are equal to each other.
  • Actively and automatically controlling the feeding device parameter K is carried out by decreasing the feeding device parameter K if the detected resistance parameter Z is smaller than the first threshold Z 1 .
  • the amplitude of the feeding device parameter K decrease is based on, for example directly proportional to, the difference between the first threshold Z 1 and the detected resistance parameter Z.
  • the detecting of the resistance parameter Z is represented in Figure 4 by block S1.
  • the evaluation about whether the detected resistance parameter Z is smaller than the first threshold Z 1 can be considered represented in Figure 4 globally by block S2 and block S3. It is to be noted that, in block S2, it is evaluated whether the detected resistance parameter Z falls within the range from first threshold Z 1 to second threshold Z 2 . If the detected resistance parameter Z falls within this range, the method returns to the detecting S1 of the resistance parameter Z. If the first threshold Z1 is equal to second threshold Z 2 , the falling of the detected resistance parameter Z within this range means that the detected resistance parameter Z is equal to the first threshold Z 1 and equal to the second threshold Z 2 .
  • Decreasing the feeding device parameter K is represented in Figure 4 by block S6.
  • the position Y is automatically and actively controlled in a closed loop way with a reference or setpoint variable Y 0 .
  • the machine 1 is configured so that an increase of the feeding device parameter K produces a decrease of the tension, and a decrease of the feeding device parameter K produces an increase of the tension. Therefore, if the detected resistance parameter Z is less than the first threshold Z1, decreasing the feeding device parameter K produces a desired increase of the tension.
  • the position control system PCS is actively and automatically controlled by controlling the reference variable Y 0 . Therefore, actively and automatically controlling the position Y is actively and automatically controlled by controlling the reference variable Y 0 .
  • the tension control system TCS controls the position control system PCS by controlling the reference variable Y 0 on which the feedback control of the position control system PCS is based.
  • the reference variable Y 0 is controlled by increasing the reference variable Y 0 if the detected resistance parameter Z is smaller than the first threshold Z 1 .
  • the amplitude of the reference variable Y 0 increase is based on, for example directly proportional to, the difference between the first threshold Z1 and the detected resistance parameter Z.
  • Increasing the reference variable Y 0 is represented in Figure 4 by block S7.
  • increasing the reference variable Y 0 can allow the web tension, during the transient of the feeding device 8, to increase more than it would do without the increase of the reference variable Y 0 , and therefore can compensate the transient of the feeding device 8. In this way the controlling of the tension is quicker.
  • Actively and automatically controlling the feeding device parameter K is carried out by increasing the feeding device parameter K if the detected resistance parameter Z is greater than the second threshold Z 2 .
  • the amplitude of the feeding device parameter K increase is based on, for example directly proportional to, the difference between the detected resistance parameter Z and the second threshold Z 2 .
  • the buffer unit 10 is located downstream of the feeding device 8 according to the feeding direction D1, increasing the feeding device parameter K produces a desired decrease of the tension.
  • the reference variable Y 0 is controlled by decreasing the reference variable Y 0 if the detected resistance parameter Z is greater than the second threshold Z 2 .
  • the amplitude of the reference variable Y 0 decrease is based on, for example directly proportional to, the difference between the detected resistance parameter Z and the second threshold Z 2 .
  • decreasing the reference variable Y 0 can allow the web tension, during the transient of the feeding device 8, to decrease more than it would do without the decrease of the reference variable Y 0 , and therefore can compensate the transient of the feeding device 8. In this way the controlling of the tension is quicker.
  • an excessive rise of the tension causes automatically a reduction of the position Y and an increase of the feeding device parameter K, thereby decreasing the tension very quickly and/or precisely.
  • an excessive lowering of the tension causes automatically an increase of the position Y and a decrease of the feeding device parameter K, thereby increasing the tension.
  • the tension control system TCS is configured for detecting the resistance parameter Z through the buffer motor BM.
