Abstract: A system and method for analyzing and controlling various parameters of a paper machine in its operation, in particular in the forming section of the paper machine, including but not limited to characteristics relating to foil blades wherein the activity and drainage characteristics associated with the blades, along with other parameters like sheet activity, sheet and fabric acceleration, sheet and fabric deflection, moisture profiles, and drainage, can be substantially separately and independently analyzed, established, and controlled, and for representing these parameters, settings, characteristics or configurations of the paper machine operation and the sheet being produced thereon in a diagrammatic manner on a computer screen and printouts or any computer readable medium.

Abstract: A reversible foil blade for a papermaking machine providing for a plurality of activity zones wherein the drainage and sheet activity characteristics of the blade can be independently and separately predetermined, established, and controlled. The shape of the foil blade is designed to provide both leading and trailing edges that each form an angle less than 90° with the horizontal, the paper sheet and conveying forming fabric, thereby providing different drainage and sheet activity characteristics when the blade is reversed and installed in a reverse orientation.
