A monitoring system comprising: (a) one or more sensors that monitor activity, amplitude, size, scale, duration of activity or a combination thereof of stock on a paper machine and (b) a control system in communication with the one or more sensors and one or more foil sections within the paper machine; wherein the control system measures the activity, amplitude, size, scale, duration of activity or a combination thereof of the stock and correlates the activity, amplitude, size, scale, duration of activity or a combination thereof to formation of fibers within the stock so that an angle, height, or both of the one or more foil sections are adjusted to change the activity, amplitude, size, scale, duration of activity or a combination thereof in the stock.

The present invention relates to a method for manufacturing a web or film comprising highly refined cellulose fibers in a paper machine, the method comprising the steps of: a) forming a wet web by applying an aqueous pulp suspension comprising highly refined cellulose fibers on a wire; and b) dewatering the wet web on the wire to obtain a dewatered web comprising highly refined cellulose fibers, wherein the dewatering comprises membrane assisted dewatering using a gas permeable membrane temporarily applied to the wet web, wherein the gas permeable membrane has a lower air permeability than the wire.
