Description

Trockenvorrichtung für Kopiermaschinen. Den Gegenstand des Hauptpatentes bildet ein Verfahren und eine Vorrichtung zum Trocknen, der von Kopiermaschinen erzeugten Kopien in der Weise, daß zwecks Verhütung des Verlaufens, Verziehens und Welligwerdens der Kopien diese nach dem Abschneiden auf volle Fläche gleichzeitig auf einer Unterlage aus Drahtgewebe o. dgl. einer Heißpressung ohne relative Ortsveränderung gegenüber den beiderseitigen Anlageflächen unterzogen werden.Drying device for copier machines. The subject of the main patent forms a method and an apparatus for drying that of copying machines made copies in such a way that in order to prevent bleeding, warping and If the copies become wavy, they simultaneously after they have been cut off to the full area on a base made of wire mesh or the like. Hot pressing without relative change in location opposite to the contact surfaces on both sides.

Der hierfür erforderliche starke Flächendruck läßt sich nur sehr schwierig erzielen, da sowohl die Raumfrage wie die Beschaffenheit der erwähnten Unterlage eine sehr wesentliche Rolle spielt.The strong surface pressure required for this can only be achieved with great difficulty achieve, as both the question of space and the nature of the mentioned base plays a very important role.

Bildet man, wie dies an sich am zweckmäßigsten ist, die Trockenvorrichtung als sich drehende geheizte Walze aus, gegen welche die Kopien durch ein endloses, mit gleicher Geschwindigkeit mitlaufendes, dampfdurchlässiges Metallband, den Kopieträger, gspreßt werden, dann können die Leitwalzen für dieses Band nur sehr geringe Durchmesser erhalten, weil für die Trockenvorrichtung nur wenig Raum verfügbar ist, während doch anderseits das Trocknen der Kopien außerordentlich rasch zu geschehen hat.If one forms the drying device, as is most expedient per se than rotating heated roller against which the copies pass an endless, vapor-permeable metal belt running at the same speed, the copy carrier, are pressed, then the guide rollers for this band can only very small diameter obtained because there is little space for the drying device is available, while on the other hand the drying of the copies is extremely rapid has to happen.

Es ist daher nicht möglich, als Kopieträger die gewöhnlichen gewebten Metalltücher mit befriedigendem Erfolge zu verwenden. Diese Metallgewebe sind kaum zu dauernd geradem Lauf über dünne Leitwalzen zu bringen und werden dun-h da-, dauernde Hin- und Herbiegen mit l@leincm I-Iall@in csssr um so rascher zerstört, it, starker sie gespannt sind.It is therefore not possible to use the ordinary woven as a copy carrier To use metal cloths with satisfactory results. These metal meshes are hardly to constantly run straight over thin guide rollers and become dun-h da-, permanent Bending back and forth with l @ leincm I-Iall @ in csssr destroyed the faster, it, stronger they are excited.

Infolc dessen sollen nach der in dem Haaptpatent veranschaulichten Ausführungsform diese Schwierigkeiten teilweise dadurch tungangen werden, daß die Kopien in ebener Form getrocknet werden, was aber die Schwierigkeiten nicht völlig behebt und konstruktiv minder günstig ist.Infolc of which should be illustrated in the main patent Embodiment, these difficulties are partly caused by the fact that the Copies in a flat shape can be dried, but the difficulty is not entirely fixes and is structurally less favorable.

Nach der Erfindung wird in der Weise Abhilfe geschaffen, daß der umlaufende Träger für die Kopien, der sie gegen die bekannte geheizte Walze preßt, aus einem an sich bekannten gelenkigen Metalldrahtgitter gebildet wird.According to the invention remedy is provided in such a way that the rotating Carrier for the copies, which presses them against the known heated roller, from one articulated metal wire mesh known per se is formed.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt: Abb. I ist ein Schnitt durch die Maschine quer zu den Walzenachsen.The drawing shows an exemplary embodiment of the subject matter of the invention shown schematically: Fig. I is a section through the machine across the roll axes.

Abb.2 eine Ansicht eines Stückes des gelenkigen, gitterartigen KopieCagbandes.Figure 2 is a view of a piece of the articulated, latticed copy cagband.

Die von den Messern d kommende nasse Kopie wird durch die Transportbänder f, g - der Walze h zugeleitet, um welche die Kopien durch den dampfdurchlässigen, endlosen Mitläufer i so geführt werden, daß sie während des Trocknens wesentlich auf volle Fläche gegen die Walze gepreßt werden, ohne daß sie eine relative Ortsveränderung gegen die beidseitigen Anlageflächen erleiden.The wet copy coming from the knives d is conveyed by the conveyor belts f, g - to the roller h, around which the copies are guided by the steam-permeable, endless follower i in such a way that they are pressed against the roller substantially over their full surface during drying without that they suffer a relative change in location against the contact surfaces on both sides.

Erfindungsgemäß ist der Mitläufer i gelenkig ausgebildet, z. ß. in der durch Abb. 2 gezeigten. Weise gitterartig gestaltet.According to the invention, the follower i is articulated, for. ß. in that shown by Fig. 2. Way designed like a grid.
