  Streuvorrichtung für   hydrauHMhe Bindemittet für PappenmMchinen zur Her telung   von Platten aus solchen Bindemitteln und   FMereten.   



   Bei Herstellung von Platten aus hydraulischen Bindemitteln, wie Zement und   Faser-   stoffen auf der Pappenmaschine, bereitet das Aufstreuen des hydraulischen Bindemittels auf den   Faserflor   beträchtliche Schwierigkeiten, weil die bisherigen Streuvorrichtungen eine genaue Regelung der aufgestreuten Menge des Bindemittels nicht gewährleisten, worunter die Beschaffenheit der erzeugten Platten in hohem Masse leidet. 



   Gegenstand der Erfindung ist eine Streuvorrichtung dieser Art, welche eine sehr genaue und verlässliche Regelung der aufgestreuten Menge des Bindemittels ermöglicht. 



   In der Zeichnung zeigt Fig. 1 einen Längsschnitt, Fig. 2 eine Endansicht einer Streuvorrichtung gemäss der Erfindung. 



   In einem rotierenden zylindrischen Sieb D ist ein zur Aufnahme des Zementes oder sonstigen Bindemittels dienender feststehender Kasten B eingebaut, dessen Seitenwände bis dicht an die Innenseite des Siebumfanges reichen. Der an einem Ende des Kastens aufgegebene Zement oder ein sonstiges Bindemittel wird durch eine Transport-   schnecke K über   die ganze Kastenlänge gleichmässig verteilt. Die beiden Seitenwände des Kastens, zwischen denen eine gelochte Querplatte L an Leder-oder Stoffstreifen hängt, sind federnd und gegeneinander durch geeignete Vorrichtungen, beispielsweise Schrauben   M   verstellbar. 



   Durch   Einstellung   der Seitenwände des Kastens kann die von der Vorrichtung gestreute Zementmenge sehr genau und verlässlich geregelt werden, indem selbst eine verhältnismässig kleine Verringerung oder Vergrösserung des Abstandes der freien Ränder der Seitenwinde eine Verringerung bzw. Vergrösserung der Menge des gestreuten Zementes hervorruft. Die durch Versuche festgestellte, sehr befriedigende Wirkung der Vorrichtung ist damit zu erklären, dass durch Annäherung der Rinder der Seitenwände des Kastens der Druck in der Zementmasse unterhalb der gelochten Platte L vergrössert, die Masse zusammengeballt und der Durchschnitt des Zementes durch das zylindrische Sieb ver-

  Spreading device for hydraulic binders for cardboard machines for the production of boards from such binders and fats.



   When making panels from hydraulic binders, such as cement and fibrous materials, on the cardboard machine, sprinkling the hydraulic binder onto the fiber pile causes considerable difficulties because the previous spreading devices do not guarantee precise control of the amount of binder sprinkled on, including the nature of the binder produced Platten suffers to a great extent.



   The subject of the invention is a spreading device of this type, which enables a very precise and reliable control of the amount of binding agent spread on.



   In the drawing, FIG. 1 shows a longitudinal section, FIG. 2 shows an end view of a spreading device according to the invention.



   A stationary box B is installed in a rotating cylindrical sieve D to receive the cement or other binding agent, the side walls of which extend right up to the inside of the circumference of the sieve. The cement or some other binding agent placed at one end of the box is evenly distributed over the entire length of the box by a conveyor screw K. The two side walls of the box, between which a perforated transverse plate L hangs on strips of leather or fabric, are resilient and can be adjusted relative to one another by means of suitable devices, for example screws M.



   By adjusting the side walls of the box, the amount of cement scattered by the device can be regulated very precisely and reliably, in that even a relatively small decrease or increase in the distance between the free edges of the crosswinds causes a decrease or increase in the amount of cement scattered. The very satisfactory effect of the device, which has been established through experiments, can be explained by the fact that when the cattle approach the side walls of the box, the pressure in the cement mass below the perforated plate L increases, the mass is agglomerated and the diameter of the cement through the cylindrical sieve
