ABSTRACT:
A doctor cooperates with the peripheral surface of a Yankee dryer for peeling the tissue away from the peripheral surface such that when the tissue is peeled from the surface, a series of microfolds are generated in the resultant tissue. An adjusting mechanism is connected to the doctor for adjusting an angle defined between the doctor and the peripheral surface. The arrangement is such that when the angle is adjusted, the physical dimensions of the microfolds change. A sensor is disposed downstream relative to the doctor for sensing the physical dimensions of the microfolds. A control circuit is electrically connected to the sensor and responsive to the sensor. The control circuit is electrically connected to the adjusting mechanism for varying the angle of the doctor so that the physical dimensions of the microfolds are optimized.
