Abstract:
A system for controlling the winding speed of a machine for winding a web of material onto a wound roll comprising:a) means for measuring a vibration of the wound roll as web material is wound thereon; b) means for measuring a line speed of the web of material; c) means for measuring a diameter of the wound roll; d) a controller receiving the measured line speed and diameter and calculating a wound roll rotational frequency therefrom and using the calculated wound roll rotational frequency to isolate the component of said vibration of the wound roll due to the winding speed of the winding machine; and e) a level detector in communication with the winding machine, said level detector decreasing the winding speed of the winding machine if the winding speed component of the wound roll vibration exceeds a pre-determined level; whereby excessive vibration of the wound roll is avoided.
