  Verfahren zum füllen von Pressformen mit Massen aus Faserstoffen und Bindemitteln. 



    Den Gegenstand der Erfindung bildet fin Verfahren zum Füllen von Pressformen mit Massen aus Faserstoffen und Bindemitteln, darin bestehend, dass die Masse in eine mit nachgiebigem Formboden versehene Pressform bei freiem Zulauf unter Vermittlung von rotierenden Stricheisen in dünnen Schichten eingestrichen wird, so dass die Fasern der Masse parallel zur Ebene der herzustellenden Platten zu liegen kommen. 



  Zwar ist es bereits vorgeschlagen worden, Tonmasse in eine Pressform mit nachgiebigem Boden durch über der Form rotierende Messer mit geneigten Flanken einzustreichen ; der Erfindung gemäss soll dieser Füllvorgang, bei welchem übrigens im Gegensatz zum vorliegenden die Messer in einer unter Pressdruck stehenden Materialsäule rotieren, auf Faserstoffmassen mit der vorstehend angegebenen Wirkung beschränkt werden. 



  In der Zeichnung ist das Verfahren an der Hand einer Einrichtung veranschaulicht. 



  Die in einer geeigneten Mischmaschine vorteilhaft zuerst trocken und dann nach Absiebung unter Zusatz von Wasser in Breiform hergestellte Mischung aus Faserstoffen und Bindemitteln, z. B. Zement und Asbest, gelangt aus einem über der Pressform zentral angeordneten Auslauf in die Pressform, deren beweglicher, unter Feder-oder Gewichtsdruck stehender Boden in an-   
 EMI1.1 
 herabfallende Masse auf der angehobenen Bodenplatte der Pressform verstreichen. Bei fortgesetztem Betriebe wird die Bodenplatte nach und nach herab zurückgedrängt, bis die Form gefüllt ist.

   Durch das schichtenweise Verstreichen der Masse in der Form werden die Stoffasern stets in die Plattenebene gelegt und dadurch   ein sehr widerstandsfähiges Gefüge gebildet 0 Dadurch.   dass überdies die Fasern mit ihrer Längsrichtung in konzentrischen Kreisen gelagert werden, erhält die Platte eine nach allen Richtungen gleich hohe Bruchfestigkeit. 



   Die die Mischorgane und Streichmesser tragende Spindel ist   längsverschiebbar und trägt     ein Verschlussorgan   für die Auslauföffnung, so dass diese nach beendeter Füllung der Pressform durch Senken der Spindel geschlossen wird.

  Process for filling press molds with masses of fibers and binders.



    The subject of the invention is a method for filling press molds with masses of fibrous materials and binders, consisting in that the mass is coated in thin layers in a press mold provided with a resilient mold bottom with the help of rotating wire rods, so that the fibers of the Mass come to lie parallel to the plane of the panels to be produced.



  It is true that it has already been proposed to smear clay mass into a mold with a flexible base by rotating knives with inclined flanks above the mold; According to the invention, this filling process, in which, by the way, in contrast to the present one, the knives rotate in a material column under pressure, is to be limited to pulp masses with the effect indicated above.



  In the drawing, the method is illustrated using a device.



  The mixture of fibrous materials and binders, eg. B. cement and asbestos, comes from a centrally arranged outlet above the mold into the mold, whose movable base, which is under spring or weight pressure, is
 EMI1.1
 Spread the falling mass on the raised base plate of the mold. As the operation continues, the base plate is gradually pushed back until the mold is filled.

   By spreading the mass in layers in the mold, the fabric fibers are always placed in the plane of the plate, creating a very resistant structure. In addition, the fact that the fibers are stored with their longitudinal direction in concentric circles gives the board an equally high breaking strength in all directions.



   The spindle carrying the mixing elements and doctor blades is longitudinally displaceable and carries a closure element for the outlet opening, so that it is closed by lowering the spindle after the filling of the mold has been completed.
