Paper making is a complex process involving a variety of operations. From wood preparation, to pulping, to bleaching, to the paper machine, many variables affect the finished product. In addition, the type of wood available and the type of paper produced significantly affect each paper mill’s operation.
Each paper machine is designed for a specific basis weight range and roll speed. Therefore, reliably producing quality paper requires precise control of the basis weight valve. Fluctuations in the basis weight result in uneven drying, a poorly finished product and/or waste. Consequently, this leads to a rejection of the whole roll. Mills need a high-performing, reliable, responsive actuator capable of making fine position changes without overshoot while maintaining this performance level at a high duty cycle.
