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.

A method of operating a machine for producing a fibrous web. The machine has a de-watering device with a plurality of pivotally embodied de-watering strips. In the method, an inclination angle of at least one of the de-watering strips is modified as a function of at least one parameter. The modification is effected by way of the pivoting installation which is activated by a control installation. The actual inclination angle of the at least one de-watering strip to be pivoted is detected and transmitted to the control installation. The control installation activates the pivoting installation as a function of the transmitted inclination angle.

Provided is a sheet manufacturing apparatus capable of desirably adjusting the thickness of the sheet, and forming sheets with highly uniform thickness or grammage. A sheet manufacturing apparatus configured to make a sheet from defibrated material of defibrated paper includes: a drum unit having a cylinder with a defibrated material storage space inside and multiple openings through which the defibrated material passes formed in the outside of the cylinder; an accumulator configured to accumulate the defibrated material that past the openings, forming a deposit; and a housing configured to enclose the drum unit and the accumulator, the housing having a vent through which air passes between the drum unit and the accumulator.

A lubricating device lubricates a circulating clothing of a machine for manufacturing a fibrous web. The device has a body with a feed chamber that has an inlet for supplying a pressurized liquid lubricant to the feed chamber and an outlet for discharging the lubricant therefrom. The body further has a nozzle chamber to which a nozzle for discharging the lubricant is connected. The nozzle has a flow-conducting connection to the feed chamber via the nozzle chamber and the outlet. Within the body, a diffuser is provided for diffusing the lubricant supplied through the outlet along the body, the diffuser being arranged between the outlet and the nozzle.
