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.
