Fatentirt im Deutschen Reiche vom 14. September 1884 ab.Fatentirt in the German Empire on September 14, 1884.
Der Apparat, dessen Construction aus der beiliegenden Zeichnung hervorgeht, besteht aus einer Anzahl von in einem Eisengestell entsprechend gelagerten Walzen, über welche 1. das zu färbende Papier durch ein Farbenbad hindurchgeführt, 2. zwischen welchen es geprefst wird, und nach Abscheidung der überflüssigen Farbe zum Trocknen gelangt, in Combination mit den Farbenbehältern und jenen Constructionstheilen, welche einen gleichmäfsigen Zuflufs frischer Farbe vermitteln.The apparatus, the construction of which is shown in the accompanying drawing, consists of a number of rollers correspondingly mounted in an iron frame, over which 1. the paper to be colored passed through a dye bath, 2. between which it was pressed is, and after separation of the superfluous color is dried, in combination with the paint containers and those construction parts which make one even To convey an influx of fresh paint.
Aus nachfolgendem wird hervorgehen,, in welcher Art die den Apparat bildenden Bestandtheile functioniren:From what follows it will be seen, in what way the components that make up the apparatus function:
Auf eine Walze A wird die zu färbende Papierrolle aufgesteckt; von, hier wird das Papier über eine Spannwalze B und unterhalb einer Walze C geführt, welch letztere in der Wanne D, die das Farbenbad enthält, rotirt. Nach dem Verlassen des Farbenbades läuft das Papier über die mit Kautschuk bekleidete Spannwalze E und die Führungswalze F zwischen Prefswalzen G und H; um die an der Oberfläche des Papiers überschüssige Farbe vor dem Uebertritt zu den bekannten Trockencylindern in der Richtung gegen J zu entfernen, ist nun die Einrichtung getroffen, dafs man das Papier zwischen den Walzen G und H über ein über die entsprechend gelagerten Spann- und Führungswalzen KLMNFG gespanntes Filztuch X führt, auf welches die Prefswalze H, deren Pressung durch eine in bekannter Art construirte Druckschraube Y re-" gulirt wird, das bei P durchlaufende Papier niederdrückt und die überschüssige Farbe ausprefst. The roll of paper to be colored is placed on a roller A; from, here the paper is guided over a tension roller B and below a roller C , the latter rotating in the tub D, which contains the dye bath. After leaving the paint bath, the paper runs over the rubber-lined tension roller E and the guide roller F between pref rollers G and H; In order to remove the excess ink on the surface of the paper before it passes over to the known drying cylinders in the direction towards J , the device is now made to move the paper between the rollers G and H over the appropriately mounted tension and guide rollers KLMNFG leads a tensioned felt cloth X , onto which the pre-roller H, the pressure of which is regulated by a pressure screw Y constructed in a known manner, presses down the paper passing through at P and presses out the excess ink.
Die hier ausgepreiste überflüssige Farbe fliefst von der Walze G in ein unterhalb derselben befindliches Reservoir R, sammelt sich hier an und wird neuerdings in Verwendung genommen. Da aber diese sich hier ansammelnde Farbenflüssigkeit in den meisten Fällen nicht so intensiv als das ursprüngliche Farbenbad ist, so wird dieselbe nicht direct in die Farbwand D, sondern durch ein sich seitlich an das Reservoir R anschliefsendes Rohr S zu einem Sammelbottich T geführt, wo sie sich mit aus dem Farbenbottich zufliefsender, frischer Farbe mengt, um erst dann und von hier aus durch ein Verbindungsrohr in die Wanne D zu gelangen.The superfluous color priced out here flows from the roller G into a reservoir R located below the same, collects here and has recently been used. But since this color liquid that collects here is in most cases not as intense as the original color bath, it is not led directly into the color wall D, but through a pipe S connected to the side of the reservoir R to a collecting tub T , where it mixes with fresh paint flowing in from the paint tub, only to then and from here reach tub D through a connecting pipe.
Die in dem Farbenbad der Wanne D rotirende Walze C, welche von dem fortlaufenden Papier mitgenommen und in Rotation versetzt wird, 'ist beiderseits in Hebelarmen α drehbar gelagert, welche Hebelarme selbst mit den sich an dieselben anschliefsenden Hebelarmen c in den Stützpunkten b oscilliren; durch diese Einrichtung ist es möglich, durch Niederdrücken des Hebelarmes c, welcher ein Steigen des Armes im ,Gefolge hat, behufs bequemen Einführens des Papiers die Walze C eventuell aus dem Farbenbade ganz herausheben zu können. The roller C rotating in the paint bath of the tub D, which is carried along by the continuous paper and set in rotation, is rotatably mounted on both sides in lever arms α , which lever arms themselves oscillate with the lever arms c adjoining them in the support points b; By means of this device it is possible, by pressing down the lever arm c, which causes the arm to rise in the wake, to be able to lift the roller C completely out of the paint bath for easy insertion of the paper.
Um ein zur richtigen Functionirung des Apparates nothwendiges constantes Niveau 'der Farbe in der Farbwanne D bezw. einen dementsprechend regulirten Zuflufs frischer FarbeIn order to maintain a constant level of color in the paint tray D and a correspondingly regulated supply of fresh paint
aus dem Farbenbottich zu erhalten, wird ein Schwimmer in Anwendung gebracht, der aus einer auf dem Niveau der Flüssigkeit im Sammelbottich T schwimmenden Scheibe d besteht, die im Centrum eine Stange e trägt; letztere reicht in das mit dem Farbenbottich communicirende Farbenzuflufsrohr f, wird innerhalb desselben in Kreuzrahmen g vertical geführt jjs. die diesen Theil in vergröfsertem Mafsstabe darstellende Fig. 2) und trägt an ihrem Ende eine Kautschukscheibe, h von geringerem Durchmesser als der Querschnitt des Rohres f. Diese Scheibe h dichtet nun eben dann den im Innern des Rohres f befindlichen Ring i ab, wenn das Niveau der Flüssigkeit im Sammelbottich T ein normales ist. Sinkt aber dieses Niveau, so sinkt auch der Schwimmer, die Scheibe h dichtet den Ring i nicht mehr ab und zwischen beiden fliefst frische Farbe so lange ringsum nach, bis das normale Niveau wieder hergestellt, h gegen i also abgedichtet ist.To obtain from the paint tub, a float is used consisting of a disk d floating at the level of the liquid in the collecting tub T and carrying a rod e in the center; The latter reaches into the paint supply pipe f communicating with the paint tub, is inside it in a cross frame g vertical jjs. 2), which shows this part on a larger scale, and at its end has a rubber disk, h of smaller diameter than the cross-section of the tube f. This disk h now seals the ring i located inside the tube f when that The level of the liquid in the sump T is normal. But if this level sinks, the float sinks too, the disk h no longer seals the ring i and fresh paint flows around between the two until the normal level is restored, i.e. h is sealed against i.
In Fig. 2 der beiliegenden Zeichnung ist der Schwimmer bei abnormalem Niveau gezeichnet, wobei also h gegen i nicht abgedichtet erscheint und zwischen beiden ringsum frische Farbe nachfliefst.In Fig. 2 of the accompanying drawing, the float is shown at an abnormal level, so h does not appear to be sealed off from i and fresh paint flows around between the two.
