 mässig. Da die ganze auf der Papiermaschine zu verarbeitende Stoffmenge durch den   Dichteregler   geleitet wird, werden   Unregelmässigkeiten   und Störungen vermieden, welche bei der Dichtemessung von Teilströmen auftreten können. 



   Das Zuteilen des Stoffes vom Regler zur Papiermaschine kann über einen an sich bekannten Teilschieber erfolgen, der entsprechend der herzustellenden Papiermenge eingestellt werden kann. Gemäss der Erfindung kann dies aber auch so geschehen, dass dem Zellenrad, der Erzeugung entsprechend, ver-   änderliche   Drehzahlen gegeben werden.

   Da mit sinkender Stofflieferung durch das Zellenrad auch der Stau sinken und damit die Grundlage der   Dichtenregelung   geändert werden würde, so wird diesem   Um-

Hiedurch   wird Wellenbildung und ein Pendeln des   Dirhtefühlers   C beim Entleeren der Zellen vermieden. 



   PATENT-ANSPRÜCHE :
1. Vorrichtung zum Regeln des relativen Fasergehaltes (der Dichte) von Stoffwassergemisehen für die Papierherstellung mit Hilfe eines von einem Schwimmer od. dgl. abzutastenden Stoffstaues, dadurch gekennzeichnet, dass zwischen der   Zugabestelle   des durch den   Dichtefühler   (C) gesteuerten   Sehiebers   (E) für das Verdünnungswasser und dem vom   Dichtefühler   (C) abgetasteten Stoffstau eine angetriebene   Mengenmessvorrichtung,   z. B. ein Zellenrad (B) zum Gleiehhalten der Menge des gesamten Stoffstroms einschliesslich des   Verdünnungswassers vorgesehen   ist.

 EMI2.1
 moderate. Since the entire amount of substance to be processed on the paper machine is passed through the density regulator, irregularities and disruptions that can occur when measuring the density of partial flows are avoided.



   The allocation of the substance from the regulator to the paper machine can take place via a known partial slide, which can be adjusted according to the amount of paper to be produced. According to the invention, however, this can also be done in such a way that the cell wheel is given variable speeds in accordance with the generation.

   As the volume of material supplied by the cellular wheel decreases, the jam also decreases and the basis of the density control would be changed, so this change
 EMI2.2
 Holes can flow into the still full cell when the substance flows out of a cell, air from the nearby cell, as long as the outer edge of the cell wall has not yet emerged. This avoids the formation of waves and oscillation of the wire feeler C when the cells are emptied.



   PATENT CLAIMS:
1. Device for regulating the relative fiber content (the density) of pulp water mixtures for papermaking with the aid of a swimmer od the dilution water and the stock jam sensed by the density sensor (C) a driven quantity measuring device, e.g. B. a cellular wheel (B) is provided to keep the amount of the total material flow including the dilution water level.
