Description

Prossblech zum Entwässern feuchter Pappen.
Bei der Fabrikation von Pappen bmtet das Trocknen derselben die Hauptschwierigkeit.
Bekanntlich wird das überschüssige Wasser zwischen eingelegten Eisenblechen auf Spindelpressen oder hydraulischen Pressen herausgedrückt. Das Wasser und vor allem die zwischen den Pappen befindliche Luft können bei diesem Verfahren naturgemäss nur an den Seiten und somit nur schwer und unvollkommen entweichen. Auch bei den gelochten Pressblechen geschieht das Auspressen unvollkommen, da die Luft und das Wasser sich immer erst seitlich bis zu den betreffenden ziemlich weit voneinander angebrachten Löchern durchdrucken müssen, um abfliessen zu können.
Den Gegenstand der Erfindung bildet nun ein Pressblech, bei dem diesen fjbelständen dadurch abgeholfen ist, dass es aus kreuzweise übereinander befestigten, einen Zwischenraum lassenden Flacheisenstäben besteht.
Dieses Pressblech ist in der Zeichnung in Fig. l in Vorderansicht und in Fig. 2 in Seitenansicht dargestellt.
Wie aus der Zeichnung ersichtlich ist, besteht das Pressblech aus einzelnen kreuz-
EMI1.1
zwischen zwei Stäben stets ein kleiner Zwischenraum b bleibt. Die gegenseitige Befestigung der Flacheisenstabe kann z. B. durch Nietung erfolgen. Durch diesen Zwischenraum kann nun Luft und Wasser von jeder Stelle der zu pressenden Pappen ungehindert entweichen.
Dadurch werden die Pappen fast ganz entwässert und können in einem wesentlich kürzeren Zeiträume austrocknen. Auch das Auspressen selbst geht viel schneller von statten.

Pross plate for draining damp cardboard.
In the manufacture of paperboard, the main difficulty is drying it.
As is known, the excess water is pressed out between inserted iron sheets on screw presses or hydraulic presses. With this method, the water and, above all, the air between the cardboard can naturally only escape on the sides and thus only with difficulty and imperfectly. Even with the perforated press plates, the pressing out happens imperfectly, since the air and the water always first have to press their way laterally to the relevant holes, which are made quite far from one another, in order to be able to flow away.
The subject matter of the invention is a press plate, in which these fjbel stands are remedied by the fact that it consists of flat iron rods which are fastened crosswise on top of one another and leave a gap.
This press plate is shown in the drawing in FIG. 1 in a front view and in FIG. 2 in a side view.
As can be seen from the drawing, the press plate consists of individual cross
EMI1.1
a small space b always remains between two rods. The mutual attachment of the flat iron bars can, for. B. be done by riveting. Through this gap, air and water can now escape unhindered from any point on the cardboard to be pressed.
As a result, the cardboard is almost completely drained and can dry out in a much shorter period of time. The pressing itself is also much faster.
