   Die Walzen   a und al-sind   mit den versenkten Formen b versehen. Sie werden nach bekannter Art ruckweise angetrieben, wobei sich die Formenhälften im Einzug der Walzen zu vollen Formen   zusammenschliessen.   In Fig.   f   sind über dem Einzug eine Presse c für feuchtes Gut und zwei Ausläufe d und d1 von Silos für trockenes Gut angedeutet. Die Materialzuführungen werden selbsttätig geöffnet, sobald die radialen Formwände e und   e1   sich in der   Mittelebene berühien,   wie es bei gezeichnet ist. In dem Augenblick ist die Form nach unten abgeschlossen.

   Zuerst   fliesst   etwas Trockenmasse hinein und dann erst kommt der feuchte Klumpen, dessen Inhalt nur einen Teil des ganzen   Formraumes ausmacht, so dass   er rings von Trockenmasse umzogen werden kann. 



   Bei der Konstruktion für die Vorpressung von Schalen (Fig. 2) liegt über dem Einzug des 
 EMI2.1 
 Presse c der feuchte Masseklumpen hinein. 



   Die Betätigung der Füllvorrichtungen, Pressstempel und der Zuführungspresse zu den richtigen Zeitpunkten wird nach bekannten konstruktiven Regeln besorgt. 



   PATENT. ANSPRÜCHE :
1. Verfahren zur Herstellung von Formlingen aus Zementrohmasse durch Halbtrockenpressung, dadurch gekennzeichnet, dass ein feuchter   Masseklumpen   aussen mit trockener pulveriger Masse umhüllt und der so vorbereitete Körper zusammengepresst wird.

   The rollers a and al- are provided with the recessed shapes b. They are driven in jerks in a known manner, the mold halves closing together to form full molds as the rollers are drawn in. In Fig. F, a press c for moist material and two outlets d and d1 of silos for dry material are indicated above the intake. The material feeds are opened automatically as soon as the radial mold walls e and e1 touch each other in the central plane, as shown at. At that moment the form is closed downwards.

   First some dry matter flows into it and only then does the moist lump come, the contents of which only make up part of the entire mold space, so that it can be surrounded by dry matter.



   In the construction for the pre-pressing of shells (Fig. 2) is above the indentation of the
 EMI2.1
 Press c the moist lump of mass into it.



   The actuation of the filling devices, ram and the feed press at the right times is done according to known design rules.



   PATENT. EXPECTATIONS :
1. A process for the production of moldings from raw cement mass by semi-dry pressing, characterized in that a moist lump of mass is enveloped on the outside with dry powdery mass and the body thus prepared is pressed together.

 

Claims (1)

2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass aus der trockenen Masse Schalen vorgepresst werden, in die dann der feuchte Masseklumpen hineingelagert wird, worauf das Zusammenpressen folgt. 2. Embodiment of the method according to claim 1, characterized in that shells are pre-pressed from the dry mass, in which the moist lump of mass is then stored, followed by the compression. 3. Vorrichtung zur Ausführung des Verfahrens nach Anspruch 1, bestehend aus zwei ruckweise gegeneinander bewegten, mit Formöffnungen (b) versehenen Walzen (a, al), dadurch gekennzeichnet, dass über dem Einzug entsprechend den Formreihen Pressen (c) für feuchte Masse und beiderseits von diesen Silos (d, d1) mit Trockenmasse münden, die absatzweise so geöffnet werden, dass das Mehl etwas vor dem feuchten Masseklumpen voreilt. 3. Apparatus for carrying out the method according to claim 1, consisting of two jerky against each other, with mold openings (b) provided rollers (a, al), characterized in that over the feed according to the series of molds presses (c) for moist mass and both sides from these silos (d, d1) open with dry matter, which are opened intermittently in such a way that the flour leads slightly in front of the moist lump of matter. 4. Vorrichtung zur Ausführung des Verfahrens nach Anspruch 2, bestehend aus zwei ruckweise gegeneinander bewegten Walzen (a, al) mit versenkten, einander entsprechenden Form- EMI2.2 und Pressstempel 1 (g, g1) zur Bildung von Schalen (i, i1) vorgesehen sind, während die Pressen (c) für den m die Schalen kommenden feuchten Masseklumpen über dem Einzugsscblitz der Walzen gelagert sind. 4. Apparatus for carrying out the method according to claim 2, consisting of two jerkily mutually moving rollers (a, al) with recessed, corresponding shape EMI2.2 and press rams 1 (g, g1) for forming shells (i, i1) are provided, while the presses (c) for the moist lump of mass coming into the shells are mounted above the intake flash of the rollers.
