ABSTRACT:
Apparatus and method for controlling a paper making machine so as to improve the uniformity and quality of the manufactured paper; wherein slicing devices are provided for operating in such direction that a detected profile matches a predetermined profile. The paper making machine comprises a plurality of slices, supply of raw material to make the paper, and sensor for measuring the quality of the paper. The controller comprises mechanism for determining the positional correspondence between a point measured by the sensor and one of the slices; mechanism for executing arithmetic operations on deviations between the detected profile and the detected profile according to the positional correspondence; mechanism for executing arithmetic operations on deviations between the detected profile and the desired profile for virtual slices provided between the slices; mechanism for providing one or more rules for operating the slices, for computing coincident degree of operating rule for rules using deviations of each slice and virtual slice adjacent thereto, and for extracting one of the rules based on the coincident degree; mechanism for determining which slices are the operation objects in accordance with extending wrinkle norms by comparing coincident degree for each slice; and control device for sending a controlled variable to the slices in accordance with operation rules previously selected.
