Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Aus in Abstand verbundenen, gelochten Platten bestehende Preßplatten, welche man insbesondere beim Auspressen feuchter Pappen und anderer feuchter Massen in den Preßstapel einlegt, um während des Auspressens das Wasser abzuleiten, sind bekannt. Diese Preßplatten haben den Ubelstand, daß sich die hohlliegenden Flächen leicht durchbiegen. Um diesen Ubelstand zu beseitigen, wurden bereits zwisehen den Löchern Stehbolzen verteilt. Nach der Erfindung wird in den Raum zwischen den beiden gelochten Platten Wellblech eingelegt. Diese Einlagen, die die Flächen stramm absteifen, ohne das Abfließen des Wassers zu hindern, verbilligen die Herstellung der Preßplatten. Compression plates consisting of perforated plates connected at a distance, which one in particular when pressing moist cardboard and other moist masses into the press pile, to drain the water during the squeezing process are known. These press plates have the disadvantage that the hollow surfaces bend easily. To this one To remove the problem, stud bolts have already been placed between the holes. To the invention is placed in the space between the two perforated plates of corrugated iron. These inserts that stiffen the surfaces tightly without preventing the water from running off prevent, cheaper the production of the press plates.

In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt, und zwar in einer Draufsicht (Fig. 1) und einem Querschnitt (Fig. 2).In the drawing, an example embodiment of the invention is shown, and although in a plan view (Fig. 1) and a cross section (Fig. 2).

Zwei gelochte Bleche a, durch Zwischenstege b getrennt, bilden die Preßplatte. Diese Platten oder eine Anzahl derselben wird in den Preßstapel eingefügt, so daß immer je ein gewisser Teilstoß des Preßgutes zwischen zwei Preßplatten eingeschlossen ist. Das Wasser gelangt beim Pressen in je einen Hohlraum, aus welchem es leicht abfließt.Two perforated sheets a, separated by intermediate webs b , form the press plate. These plates or a number of the same is inserted into the press stack, so that a certain part of the material to be pressed is always enclosed between two press plates. When pressed, the water enters a cavity from which it flows easily.

Zur Verhinderung des Durchbiegens ist nach der Erfindung in jeden Hohlraum eine Wellblechtafel c eingelegt, und zwar so, daß sie gerade gedrängt hineinpaßt, wobei die Anfangs- und Schlußwelle gegen den Steg b anliegt, während die Rinnen nach den offenen Seiten münden. Eine solche Preßplatte bietet einen großen Druckwiderstand, da die Wellen nicht ausweichen können, wodurch ein Durchbiegen selbst dünner Böden verhindert wird. To prevent sagging, a corrugated sheet metal c is inserted into each cavity according to the invention, in such a way that it just fits tightly into it, the initial and final wave rests against the web b , while the channels open to the open sides. Such a press plate offers a great pressure resistance, since the waves cannot escape, which prevents bending of even thin floors.
