Description

KLASSEGREAT

Bei den vorhandenen Streich- und Trocknungseinrichtungen für Papier oder Gewebe u. dgl. wird die Zuführung von Trocknungswärme, sei es dafs dieselbe durch Heizplatten, Heizcylinder oder heifse, trockene Luft u. s. w. erfolgt, kurz nach Verlassen der Streichvorrichtung bewirkt. Diese Processe verlangsamen, wenn das Material sich nicht durch Einrollen oder Brechen für die weitere Bearbeitung unbrauchbar machen soll, die Trocknung ungemein, so dafs oft ausgedehnte Einrichtungen mit langsamem Durchlauf und grofser Raumverschwendung eingerichtet werden müssen.With the existing coating and drying facilities for paper or fabric and the like, the supply of drying heat, be it through heating plates, Heating cylinder or hot, dry air etc. takes place shortly after leaving the coating device causes. These processes slow down if the material is not curling up or breaking is supposed to make it unusable for further processing, the drying is immense, so that often extensive facilities with slow throughput and great waste of space need to be set up.

Der Grund für die lange Dauer der Trocknung ist darin zu suchen, dafs zur Verdampfung der in der Streichmasse enthaltenen Flüssigkeit Wärme benöthigt wird, die zum Theil dem Material, zum Theil der umgebenden Aufsenluft entzogen werden mufs, wodurch beide Theile abgekühlt werden, während gleichzeitig die Aufnahmefähigkeit der Luft für die verdampfte Flüssigkeit' verringert wird, ein Umstand, der wiederum eine Verlängerung von Trocknungsbahn und Trocknungsdauer verursacht.The reason for the long duration of drying is to be found in the fact that it leads to evaporation The liquid contained in the coating requires heat, which is partly due to the material and partly to the surrounding material Outside air must be withdrawn, whereby both parts are cooled, while at the same time the absorption capacity of the Air for the vaporized liquid 'is reduced, a circumstance which in turn is an extension caused by drying path and drying time.

Das vorliegende Verfahren hilft diesem Uebelstande dadurch ab, dafs ein grofser Theil der für die Verdampfung nöthigen Wärme dem Papier oder Stoff wie auch der Streichmasse vor Eingang in den Streichprocefs mitgetheilt wird.The present procedure remedies this inconvenience by the fact that a large part the heat necessary for evaporation, the paper or fabric as well as the coating slip is communicated prior to entry in the spreading process.

Erreicht wird dieses dadurch, dafs das Papier oder der Stoff vor dem Bestreichen über geheizte Platten oder Cylinder geführt wird, und dafs eventuell gleichzeitig die Streichmasse, welche bei den gebräuchlichen Anordnungen ebenfalls lediglich Raumtemperatur besitzt, voider Benutzung so hoch, wie es ohne Schaden für die Eigenschaften derselben geschehen kann, vorgewärmt wird. Nach Verlassen der Streichvorrichtung wird das hocherwärmte, bestrichene Material durch Absaugen der feuchten und Zuführung vorgewärmter, trockener Luft einer gleichmäfsigen, nicht scharfen Trocknung unterworfen.This is achieved by the fact that the paper or fabric is over heated before it is coated Plates or cylinders is guided, and that possibly at the same time the coating, which also only has room temperature in the usual arrangements, voider Use as high as can be done without harm to the properties of the same can be preheated. After leaving the coating device, the highly heated, coated Material by sucking off the moist and supplying preheated, dry air for an even, non-sharp drying subject.
