Description
Entwicklungsmaschine für Lichtpausen mit einer in ein Flüssigkeitsbecken eintauchenden Entwicklungswalze Maschinen zur Feuchtentwicklung von Lichtpausen, die mit einer die Pausen mit Entwickelflüssigkeit benetzenden Walze sowie mit einer der Entwicklungswalze zugeordneten Transportwalze arbeiten, sind bekannt.Developing machine for blueprints with one in a liquid pool submerged developing roller machines for the moisture development of blueprints, with a roller wetting the pauses with developing liquid and with a work associated with the development roller transport roller are known.
Aus der Bauart der bekannten Maschinen, insbesondere aus der Lage der bei ihnen verwendeten Transportwalzen zu den Entwicklerwalzen ergab sich, daß die Schichtseite der zu entwickelnden Papiere während des Durchgangs der letzteren durch die Maschine stets nach unten gekehrt war, so daß sie dem Auge in nachteiliger Weise verborgen blieb. Auch mußten die Papiere, welche der Entwicklungsmaschine nach der Behandlung in der Belichtungsvorrichtung mit der Schichtseite nach oben zugeführt wurden, immer erst umgedreht werden, um die Schichtseite auf die Unterseite zu bekommen. Aus diesem Grunde war es z. B. nicht möglich, eine fortlaufende, der Fließbandherstellung dienende Entwicklung zu erzielen.From the design of the known machines, in particular from the location the transport rollers used in them to the developer rollers showed that the layer side of the papers to be developed during the passage of the latter was always turned down by the machine, so that it was more disadvantageous to the eye Way remained hidden. Also the papers, which of the developing machine had to after treatment in the exposure device with the layer side up have to be turned over first, with the layer side on the underside to get. For this reason it was z. B. not possible a continuous, the To achieve development that serves assembly line production.
Nach der Erfindung ist die Transportwalze derart neben der Entwicklerwalze gelagert, daß die Achsen beider Walzen in einer horizontalen oder annähernd horizontalen Ebene liegen und daß die Pausen von unten nach oben durch das Walzenpaar gehen. Gegebenenfalls kann zwischen Entwicklerwalze und Transportwalze noch eine Zwischenwalze angeordnet werden.According to the invention, the transport roller is next to the developer roller stored that the axes of both rollers in a horizontal or approximately horizontal Level and that the breaks go from bottom to top through the pair of rollers. If necessary, an intermediate roller can also be used between the developer roller and the transport roller to be ordered.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.The invention is shown in an exemplary embodiment in the drawing.
Es zeigt darin Fig. i eine Seitenansicht der Maschine, während Fig. 2 eine weitere Ausbildung der Entwicklungsmaschine ebenfalls in Seitenansicht darstellt.It shows FIG. I a side view of the machine, while FIG. 2 shows a further embodiment of the developing machine, also in side view.
Nach Fig. i ruht die Entwicklungswalze a in festen Lagern, während die Transportwalze b seitlich von dieser verstellbar gelagert ist. Unterhalb der Entwicklungswalze a befindet sich ebenfalls unverstellbar das Entwicklerb.ecken t. Die Entwicklerflüssigkeitwird unmittelbar von der Entwicklerwalze a auf das belichtete Papier aufgetragen, dessen Bahn in der Führung g entlang durch Pfeile bezeichnet ist. Hierdurch wird erreicht, daß die Papierbahn mit der Schichtseite nach oben durch die Maschine geführt werden kann. Nachdem die entwickelte Papierbahn die Walzen a und b passiert hat, gelangt sie, wie üblich, in den Auffangtisch la.According to Fig. I, the developing roller a rests in fixed bearings, while the transport roller b is mounted to be adjustable to the side of this. Below the Development roller a is also unadjustable, the corner of the developer t. The developer liquid is applied directly from the developer roller a to the exposed Applied paper, the path of which is indicated in the guide g along by arrows is. This ensures that the paper web is with the layer side up can be guided through the machine. After the developed paper web the rollers a and b, it ends up in the catch tray la as usual.
Nach Fig.2 ist zwischen Entwicklerwalze a und Transportwalze b eine Zwischenwalze c eingeschaltet, wodurch in an sich bekannter Weise eine gleichmäßige Verteilung der Entwicklerflüssigkeit erzielt wird.According to Figure 2 between the developer roller a and transport roller b is a Intermediate roller c switched on, whereby a uniform in a manner known per se Distribution of the developer liquid is achieved.
Eine weitere die Entwicklerflüssigkeit verteilende Walze e ist über der Walze a verstellbar gelagert. Unterhalb der Zwischenwalze c ist ein Abtropfbecken d vorgesehen. Die Transportwalze b ist zweckmäßig profiliert, damit die Papierbahn sicher weitergezogen wird.Another roller e distributing the developer fluid is over the roller a is adjustable. Below the intermediate roller c is a drip tray d provided. The transport roller b is appropriately profiled so that the paper web is sure to move on.
Es können auch, ohne am Wesen der Erfindung etwas zu ändern, besondere Transportwalzenpaare für die Papierbahn eingeschaltet werden.It can also be special without changing the essence of the invention Transport roller pairs are switched on for the paper web.
