System and method for producing paper are provided. The system controls formation of wet stock comprising fibers on a moving water permeable wire of a de-watering machine that has means for supplying the amount of pulp from at least one source, means for adding an amount of non-fibrous additives to the wet stock, a refiner that is subject to a variable load and a headbox having at least one slice, wherein each slice has an aperture through which wet stock is discharged onto the wire. The system includes: (a) at least two water weight sensors that are positioned adjacent to the wire wherein the at least two sensors are positioned at different locations in the direction of movement of the wire and upstream from a dry line which develops during operation of the machine and the sensors generate signals indicative of a water weight profile made up of a multiplicity of water weight measurements; and (b) means for adjusting at least one of the motor load controller, the amount of non-fibrous additives added to the wet stock or amount of pulp supplied from the at least one source to cause the water weight profile to match a preselected or optimal water weight profile.
A method of controlling the formation of a sheet of wet stock comprising fibers wherein the wet stock is formed on a water permeable moving wire of a de-watering machine that has means for supplying an amount of pulp from at least one source, means for adding an amount of non-fibrous additives to the wet stocks, a refiner that subjects the fibers to mechanical action, said refiner being subject to a variable load, and a headbox having at least one slice, wherein each slice has an aperture through which wet stock is introduced onto the wire, said method comprising the steps of:
A system of controlling the formation of wet stock, in the production of a dried sheet product, which comprises fibers on a moving water permeable wire of a de-watering machine that comprises means for supplying an amount of pulp from at least one source, means for adding an amount of non-fibrous additives to the wet stock, a refiner that subjects the fibers to mechanical action, said refiner having a motor load controller, and a headbox having at least one slice, wherein each slice has an aperture through which wet stock is discharged onto the wire, which system comprises:
