KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung hat den Zweck, die bis jetzt zum Trocknen von Papier, Pappen u. s. w. verwendeten gufseisernen Cylinder zu ersetzen, wodurch besonders dem Uebelstande ganz vorgebeugt ist, welcher bei Verarbeitung feiner Papiere durch Ansetzen von Rost und Schmutz an den gufseisernen. Cylindern sehr störend auf die Fabrikation einwirkt. Das bei vorliegender Erfindung zum Trocknen des Papiers zur Verwendung kommende Metallblech bietet dem Papier immer eine vollkommen rost- und schmutzfreie Unterlage. Es ist ferner zu berücksichtigen, dafs das zur Herstellung des Bleches dienende Material vollständig porenfrei ist, mag dasselbe aus Messing, Kupfer, Stahl oder anderen Metalllegirungen bestehen.The present invention has the purpose, up to now, for drying paper, cardboard and so on is completely prevented, which when processing fine papers by the build-up of rust and Dirt on the cast iron. Cylinders has a very disruptive effect on manufacture. That at Metal sheet used in the present invention for drying the paper always offers the paper a completely rust-free and dirt-free base. It is also to be taken into account that the The material used to make the sheet metal is completely pore-free, like brass, Copper, steel or other metal alloys exist.

Von Bedeutung ist die Erfindung besonders bei der Fabrikation einseitig glatter Papiere; es kommt hierbei einzig und allein auf die Erzeugung einer Spiegelglätte auf einer sogenannten spiegelblanken Unterlage an. Diese Eigenschaften besitzt nun dieser Apparat in hervorragender Weise.The invention is of particular importance in the manufacture of papers that are smooth on one side; the only thing that matters here is the creation of a mirror smoothness on a so-called mirror-like base. This apparatus now possesses these properties in an excellent manner.

Beiliegende Zeichnung veranschaulicht eine Trockenparthie zur Erzeugung einseitig wie auch maschinenglatter Papiere. Die von der Presse P kommende nasse Papierbahn P1 wird über die Leitwalzen L auf das erste Metallblech- B überführt, welches wie auch die folgenden Trockenbleche über Walzen W läuft.The accompanying drawing illustrates a dryer section for producing one-sided as well as machine-smooth papers. The wet paper web P 1 coming from the press P is transferred via the guide rollers L to the first metal sheet B , which, like the following drying sheets, runs over rollers W.

Durch diese Walzen wird auch die fortwährend nöthige Anspannung des Bleches, welche durch seine Ausdehnung bedingt ist, bewerkstelligt. Dieses erste Metallblech läuft ohne Filz. Von hier aus gelangt die Papierbahn auf die mit Filzführung versehenen Trockenbleche II und III. Von dem Trockenblech III wird die Papierbahn zur Erlangung einseitiger Glätte auf das Trockenblech Uli geführt, welches ebenfalls mit Filzleitung und Filztrockencylindern versehen ist. Zur Führung des Bleches dienen die Walzen W1,. zur Führung des Filzes die Leitwalzen L1. W ist die zur Erzeugung einseitiger Glätte nöthige Filzwickelwalze. Nach Verlassen dieses grofsen Trockenbleches kann die Papierbahn nochmals über Trockenbleche V und VI, welche ebenfalls mit Filzführung versehen sind, geführt werden.It is through these rollers that the continually necessary tensioning of the sheet, which is conditioned by its expansion, is brought about. This first sheet of metal runs without felt. From here the paper web arrives at the drying trays II and III, which are provided with felt guides. To achieve smoothness on one side, the paper web is guided from the drying plate III onto the drying plate Uli, which is also provided with a felt line and felt drying cylinders. The rollers W 1 serve to guide the sheet . guide rollers L 1 to guide the felt . W is the felt winding roller necessary to produce one-sided smoothness. After leaving this large drying tray, the paper web can be guided again over drying trays V and VI, which are also provided with felt guides.

Die Erwärmung des Bleches erfolgt mittelst an der Innenseite angebrachter Dampf heizrohren an welchen das Metallblech dicht vorbeiläuft. An Stelle der Heizrohre können auch gufseiserne oder von Eisenblech hergestellte Kasten verwendet werden.The sheet is heated by means of steam heating pipes attached to the inside which the sheet metal passes close by. Instead of the heating pipes, cast iron ones can also be used or boxes made of sheet iron can be used.
