Device useful for sectional dosing of fluid medium into further fluid medium deployable over dispensing region extending in transverse direction, comprises device for transverse distribution, dosing device, and device for mixing

摘要

Device (2) for sectional dosing of at least one medium, preferably a fluid medium into a further fluid medium deployable over a dispensing region, preferably a fibrous material suspension, that extends in transverse direction, comprises: at least one device for transverse distribution of at least one fluid medium at an individual section (8); a dosing device for dosing at least one fluid medium, associated with the sections of the dispensing region; and a device for mixing the dosed medium in the further fluid medium that is deployable in the sections of the dispensing region. Device (2) for sectional dosing of at least one medium, preferably a fluid medium into a further fluid medium deployable over a dispensing region, that extends in transverse direction, preferably a fibrous material suspension that extends in machine transverse direction, comprises: at least one device for transverse distribution of at least one fluid medium at an individual section (8); a dosing device for dosing at least one fluid medium, associated with the sections of the dispensing region; and a device for mixing the dosed medium in the further fluid medium that is deployable in the sections of the dispensing region. The device for transverse distribution that is associated with the individual section, the dosing device, and the device for collateral mixing of the dosed fluid mediums, forms a structural unit. An independent claim is also included for controlling/regulating the properties of a fibrous material web, which at least indirectly characterizes the magnitude, preferably surface weight cross profile, comprises sectionally adding the media that influences the properties of the fibrous material suspension, where the local surface weight of the fibrous material web, which at least indirectly characterizes the magnitude, is detected, and while a deviation from desired value depending on at least one of the fiber- or nonwoven material suspension, which at least indirectly characterizes the magnitude, is sectionally added with the media that influences the retention, in transverse machine direction using the above device.
