  • Patent number: 11118306
    Abstract: A web forming device includes: a defibrator having a variable speed rotor, and configured to defibrate defibration feedstock by rotation of the rotor; an accumulator on which defibrated material defibrated by the defibrator accumulates; a thickness detector configured to detect a thickness of the defibrated material accumulated on the accumulator; and a controller configured to control a rotational velocity of the rotor based on a detection result from the thickness detector. The controller applies either or both a first control and a second control, the first control decreasing the rotational velocity of the rotor when variation in the thickness of the deposited defibrated material detected by the thickness detector exceeds a first tolerance, and the second control increasing the rotational velocity of the rotor when a slope of change over time in a thickness of the deposited defibrated material detected by the thickness detector is less than a second tolerance.

  • Patent number: 11118309
    Abstract: A device dewaters a wet-laid non-woven web formed from a fibrous suspension. The device has a multiplicity of dewatering strips which are disposed so as to be mutually spaced apart. Mutually neighboring dewatering strips conjointly delimit a dewatering gap for discharging liquid from the fibrous suspensions. The device further has at least three format slides which along the longitudinal direction of the respective dewatering gap are disposed or disposable so as to be distributed relative to one another and which partially obscure the dewatering gap in such a manner that any discharging of the liquid by way of the obscured part of the dewatering gap is prevented.

  • Patent number: 11041271
    Abstract: Vibration sensors can be used in paper making systems and methods to determine various aspects of the paper making operation. Vibration sensors, for example, positioned on cleaning blades configured to clean various deposits off of rollers in a paper making system can output vibration data that can be indicative of the vibration of the blade. The vibration data can be analyzed in order to characterize the cause of the vibration and/or the location of the vibration within a paper making system. If the vibration data satisfies a predetermined condition, a corrective action can be initiated. Different corrective actions can be initiated based on the characterized cause and/or location of the vibration in order to effectively improve the operation of the system while minimizing costly system shut downs and major maintenance.
