AN APPARATUS FOR MAKING TISSUE

摘要

An apparatus (10) for making tissue (T) is disclosed in which a Yankee dryer (12) has a peripheral surface (14) for supporting the tissue (T). A doctor (16) cooperates with the peripheral surface (14) for peeling the tissue (T) away from the peripheral surface (14) such that when the tissue (T) is peeled from the surface, a series of microfolds are generated in the resultant tissue. An adjusting mechanism (18) is connnected to the doctor (16) for adjusting an angle (A) defined between the doctor (16) and the peripheral surface (14). The arrangement is such that when the angle (A) is adjusted, the physical dimensions of the microfolds change. A sensor (20) is disposed downstream relative to the doctor (16) for sensing the physical dimensions of the microfolds. A control circuit (22) is electrically connected to the sensor (20) and responsive to the sensor (20). The control circuit (22) is electrically connected to the adjusting mechanism (18) for varying the angle (A) of the doctor (16) so that the physical dimensions of the microfolds are optimized.
