Patentirt im Deutschen Reiche vom 6. April 1884 ab.Patented in the German Empire on April 6, 1884.

Diese Erfindung betrifft die Durchführung von x Papier oder ähnlichem Material durch Kalander und besteht in der Anwendung von geprefster Luft, Gasen oder Dampf, um das Papier gegen die Walzen anzudrücken. Die beiliegende Zeichnung zeigt einen nach dieser Erfindung eingerichteten Kalander.This invention relates to the passage of x paper or similar material through calenders and consists in the use of pressurized air, gases or steam to press the paper against the rollers. The accompanying drawing shows a calender designed according to this invention.

i, 2, 3, 4, 5, 6, 7 und 8 sind mit den Kalanderwalzen parallel liegende Rohre, welche auf der den Walzen zugekehrten Seite eine Reihe von Löchern oder Schlitzen haben.i, 2, 3, 4, 5, 6, 7 and 8 are pipes lying parallel to the calender rolls, which have a series of holes or slots on the side facing the rollers.

Die Rohre sind mit einem Ventilator oder irgend einem Gebläse verbunden, durch welches geprefste Luft als feiner Strahl in der ganzen Breite des Kalanders gegen die Walzen geblasen wird.The pipes are connected to a ventilator or any blower through which Pressed air is blown against the rollers as a fine jet across the entire width of the calender will.

Bei manchen Papieren kann statt geprefster Luft auch Dampf benutzt werden. Das Papierblatt wird bei A eingeführt und wird, wenn es das Bestreben hat, mit der oberen Walze b zu gehen, von dem Luftstrom des Rohres 1 weggeblasen und gegen die untere Walze c angedrückt; der Luftstrom aus den Rohren 2, 3 und 4 hält das Papierblatt so länge an die Walze, bis dasselbe zum nächsten Walzenpaare gelangt.With some papers, steam can be used instead of compressed air. The sheet of paper is introduced at A and, when it tends to go with the upper roller b , is blown away by the air flow of the tube 1 and pressed against the lower roller c; the air flow from the tubes 2, 3 and 4 holds the sheet of paper against the roller until it reaches the next roller pair.

Beim Austritt aus diesem wird das Papierblatt wieder von dem Luftstrom aus Rohr 5 von der oberen Walze c gelöst und von den Rohren 6, 7 und 8 angedrückt u. s. w., bis das Papierblatt durch den ganzen Kalander durchgeführt ist.When exiting this, the paper sheet is released again by the air flow from tube 5 from the upper roller c and pressed on by the tubes 6, 7 and 8, etc., until the paper sheet is passed through the entire calender.
