Description

Poröse Formkörper, die besonders vermöge i'hrer hohen Wärme- und Schalldämmfähigkeit sich vor züglich als Isoliermaterial eignen, wurden bisher stets im chargenweisen Betrieb, beispielsweise in Einzelformen, Stück für Stück hergestellt. Porous moldings, which are particularly due to their high heat and Soundproofing properties are ideally suited as an insulating material, have always been the case up to now manufactured piece by piece in batch operation, for example in individual molds.

Die vorliegende Erfindung zeigt nun einen Weg, um 'die Herstellung von porösen Formkörpern im kontinuierlichen Arbeitsgang vorzunehmen. Zu diesem Zweck werden Bänder, die aus Papiergewebe, Gummi oder einem sonstigen Werkstoff bestehen können, die auf der fertig betriebenen Platte belassen oder abgenommen werden können, durch eine Abfülls orrichtung und anschließend durch eine Heizkammer, in der der Treibprozeß auf geeignete Weise vonstatten geht, derart geführt, daß die aus der treibenden Masse zwischen den Begrenzungshändern geformten Streifen sich bis zum gewünschten Grade ausdehnen können. Die getriebenen Platten können anschließend mit oder ohne Begrenzungsbänder gegebenenfalls noch durch eine Trocken- bzm. Neutralisationskammer geführt werden. The present invention now shows a way to 'manufacture of porous moldings in a continuous operation. To this end are tapes made of paper fabric, rubber or some other material that can be left on the already operated plate or removed, through a filling device and then through a heating chamber in which the Driving process proceeds in a suitable manner, guided in such a way that the out of the floating mass between the limiting hands formed strips up to can extend the desired degree. The driven plates can then with or without delimitation tapes, if necessary by a drying or Neutralization chamber be guided.

In der Heizkammer werden die Begrenzungsbänder durch geeignete Vorrichtungen, beispielsweise endlose Wanderformplatten u. dgl., gefüihrt. In the heating chamber, the delimitation bands are fixed by means of suitable devices, For example, endless traveling mold plates and the like.

Es können auf die erhndungsgemäße Weise sowohl poröse Betonmaterial ieh, gegebenenfalls mit geeigneten Füllstoffen, als auch poröse Runstharzformkörper oder poröse Gipsformliörper hergestellt werden. Je nach der Breite der Begrenzungsbänder können auch poröse Formplatten 'hergestellt werden. Die in der Heizkammer befindlichen Ävauderforjuplatten können zur Erzeugung einer ganz bestimmten Oberflächengestaltung der getriebenen Formkörper pofiliert ausgestaltet sein.Both porous concrete material can be used in the manner according to the invention ieh, optionally with suitable fillers, as well as porous synthetic resin moldings or porous plaster moldings are produced. Depending on the width of the delimitation bands porous mold plates can also be produced. The ones in the heating chamber Ävauderforjuplatten can be used to create a very specific surface design the driven molded body be designed profiled.

Im allgemeinen genügen zwei Begrenzungsbänder auf der Ober- und L'nterseite. Es können jedoch auch noch seitliche Begrenzungsbänder angebracht sein bzw. vier 'anderformplatten im Gleichlauf angeordnet sein. Nach einer anderen Ausfuhrungsform kann z. B. die untere Bahn breiter sein als die obere Bahn, so daß sie auf beiden Seiten um die obere Bahn umgeschlagen werden kann, so daß nach dem Treiben der Masse die obere Bahn an die umgefalzt Bahn zu liegen kommt. Ein seitliches Herausdrücken der umgebogenen Bahn wird dadurch die Belastung durch die Nvanderformplatten verhindert.In general, two limiting strips on the top and bottom are sufficient. However, lateral delimitation strips or four can also be attached 'Other mold plates be arranged in synchronism. According to another embodiment can e.g. B. the lower web be wider than the upper web, so that they are on both Pages can be turned over around the upper panel, so that after the drifting of the crowd the top sheet comes to rest against the folded sheet. A sideways push out This prevents the bent sheet from being subjected to stress by the Nvanderform plates.

Die kontinuierliche Erzeugung derartiger Formkörper kann beispielsweise folgendermaßen durchgeführt werden, wie dies die,Zeichnung veranschaulicht. ueber ein verstellbares Walzenpaar a ist der Vorratsbehälter für die formbare Masse angebracht. The continuous production of such shaped bodies can, for example be performed as follows, as illustrated in the drawing. above an adjustable pair of rollers a is attached to the storage container for the mouldable mass.

An dem Vorratsbehälter b, der mit einer Streichschablone c versehen ist, werden über das Walzenpaare die Begrenzungsbänder d geführt. Der fertige ungetriebene Streifen e wandert nun in die Heizkammer f und wird darin durch zwei endlose Wanderformplatten g, deren Abstand verändert werden kann, geführt. Die seitliche Begrenzung kann ebenfalls durch zwei Wanderformplatten erfolgen. Durch die zugeführte Wärme fängt die Masse an zu treiben und hat sich beispielsweise bei h endgültig an die Wanderformplatteng angelegt. Bei i werden eventuell auftretende Dämpfe abgeführt. Der getriebene Streifen kann anschließend durch eine zweite Trockenkammer und/oder durch eine Neutralisationskammer beispielsweise bei der Verarbeitung von Kunstharz, das durch Säurezusatz verfestigt wurde, geleitet werden. Der fertige Streifen kommt dann anschließend beispielsweise auf einen Walzentisch K und wird bei I durch eine geeignete Schneidvorrichtung in Formkörper von gewünschter Größe zerlegt. Bei Verwendung von Papier, Gewebe od. dgl. als Begrenzungsstreifen können dieselben, vorher gegebenenfalls imprägniert, auf dem getriebenen Material verbleiben oder andernfalls als endlose Bänder ausgestattet sein, die an der Abfüllvorrichtung vorbei durch die Heizkammer und zurück wandern.On the storage container b, which is provided with a stencil c is, the limiting belts d are guided over the roller pair. The finished unpowered one Strip e now moves into the heating chamber f and is passed through two endless traveling mold plates g, the distance of which can be changed, out. The side limitation can also done by two traveling mold plates. The mass is captured by the heat supplied to drive and has, for example, finally at the Wanderformplatteng created. Any vapors that may occur are discharged at i. The chased strip can then pass through a second drying chamber and / or through a neutralization chamber for example when processing synthetic resin that solidifies when acid is added was directed. The finished strip then comes for example on a roller table K and is cut at I by a suitable cutting device in Disassembled molded body of the desired size. When using paper, fabric or The same can be used as boundary strips, if necessary impregnated beforehand, remain on the driven material or otherwise equipped as endless belts that migrate past the filling device through the heating chamber and back.
