A system (50) for controlling performance of a slitter-winder (25) and/or a fiber web production line (100) has an advisor unit (34, 36, 37) with a processor and a memory including computer program code, configured to cause the advisor unit (34, 36,37) to generate and transmit signals as first control data to the slitter-winder (25) and/or as second control data to the fiber web production line (100) based on information data received from the slitter-winder (25) and the fiber web production line (100) to control performance of the slitter-winder (25) and/or the fiber web production line (100). Performance of a slitter-winder (25) and/or a fiber web production line is controlled by receiving information data from the slitter-winder and the fiber web production line (100), processing the received information data according to a predetermined configuration, based on the processed data; generating signals according to the predetermined configuration to control the performance.

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 sheet manufacturing apparatus includes a pressing unit, a separate sheet shaping unit, a transportation unit, and a cutting-off unit. The pressing unit includes a pressing roller that presses a material containing fibers and a binder, which has a function of bonding the fibers together, to form the material into a shape of a continuous sheet. The separate sheet shaping unit cuts the continuous sheet into a shape of a separate sheet. The transportation unit is provided between the pressing roller and the separate sheet shaping unit and transports the continuous sheet formed by the pressing unit to the separate sheet shaping unit. The cutting-off unit is provided between the pressing roller and the transportation unit. When transportation abnormality occurs on the continuous sheet that is being transported, the cutting-off unit cuts off, from the continuous sheet, a part of the continuous sheet where the transportation abnormality occurs.

The problem of inconsistent steam penetration of a fibrous sheet is solved by a steam box having a steam header, a diffuser housing disposed within the steam header, wherein walls disposed in the diffuser housing divide an inside of the diffuser housing into multiple diffuser chambers, wherein a valve is configured to fluidly and programmatically communicate with each of the multiple diffuser chambers, such that a steam from the header box may selectively enter one of the diffuser chambers depending upon the valve's orientation in an open or closed position; and multiple orifices of different sizes per diffuser chamber. Ideally, exemplary steam boxes may also comprise a diffuser plates per diffuser chamber. Preferably, the diffuser plates may be located at a bottom of the diffuser chamber. Exemplary steam box systems may further comprise control equipment to manage the flow of steam from the steam header into the diffuser chambers.

A web manufacturing apparatus includes a transport section configured to transport a web containing fiber, a web humidifier configured to humidify the web, and a control section configured to control operation of the transport section and the web humidifier. When transportation of the web by the transport section is stopped, the control section causes the transport section to recommence transportation of the web after the web is humidified by the web humidifier. The control section may also cause the web humidifier to stop humidification of the web after the web humidifier starts humidification of the web and a predetermined duration elapses.

A disruptor adjustment system comprising: a disruptor assembly configured to disrupt a volume of smelt flowing from a smelt spout into a dissolving tank, wherein the disruptor assembly comprises an actuator operatively engaged to a disruptor, a sensor configured to record process data from the recovery boiler; and a control system configured to receive a sensor output signal from the sensor, wherein the sensor output signal indicates the process data at a measured time, wherein the control system is further configured to compare the sensor output signal to a programmed operation range, and to send a disruptor input signal to the disruptor assembly to adjust a disruptor operating condition if the process data of the sensor output signal is outside of the programmed operation range. In certain exemplary embodiments, the sensor is an image capture device. In certain exemplary embodiments, the disruptor assembly can be adjusted remotely.
