Abstract
A machine for one of manufacturing and processing a fiber web includes an input end which receives a fiber suspension or a fiber web. The input end includes a plurality of control modules, with each control module controlling at least one of a plurality of adjustable input parameters. A plurality of sensors are provided, with each sensor being configured to sense a physical characteristic of one of the fiber suspension and the fiber web and provide an output signal indicative thereof. A chemistry process controller is coupled with each sensor and each control module to define a closed loop control system. The chemistry process controller controls operation of each control module.
