Description

Vorrichtung zum Herstellen von Isolierband: -dgl. mit Hilfe eines Vierwalzenkalanders Zum Überziehen von Stoffbahnen mit plastischen Massen, beispielsweise mit klebrigen L7berzügen, wie bei dem Herstellen von Isolierband, ist es üblich, das Gewebe durch Friktionswalzen eines Kalanders hindurchzuführen und den überzugswerkstoff (beispielsweise eine streichfähige Kautschukmischung) zugleich mit dem Gewebe zwischen die Friktionswalzen einzuführen.Device for producing insulating tape: -like. with help of a Four-roll calender For covering fabric webs with plastic compounds, for example with sticky coatings, as in the production of insulating tape, it is common to passing the fabric through the friction rollers of a calender and the covering material (for example a spreadable rubber mixture) at the same time with the fabric between introduce the friction rollers.

Um ein Gewebe doppelseitig zu friktionieren, ist es bekannt, das Gewebe in einem Arbeitsgang durch zwei Paare von Friktionswalzen eines Kalanders hindurchzuführen, wobei das eine Doppelpaar die eine Seite und das andere Doppelpaar die andere Seite des Gewebes mit der aufzubringenden Masse versehen soll. Es ist ferner üblich, eine Stoffbahn dadurch doppelseitig mit einer Kautschukschicht zu bedecken, daß man den Stoff zwischen zwei Walzen hindurchführt, von denen jede durch eine weitere Walze mit der aufzubringenden plastischen Masse bestrichcn wird, bevor sie die Stoffbahn berührt. Dieser Vorgang stellt jedoch keine Friktion dar, sondern nur ein Einpressen des plastischem Gummis in das Gewebe, während beim Friktionieren ein Einreiben der Masse in die Stoffbahn, wie bekannt, dadurch bewirkt wird, daß die Stoffbahn zwischen zwei Walzen mit ungleicher Umfangsgeschwindigkeit hindurchläuft.In order to fractionate a fabric on both sides, it is known to use the fabric to pass through two pairs of friction rollers of a calender in one operation, with one double pair on one side and the other double pair on the other side of the tissue is to be provided with the mass to be applied. It is also common to use a To cover the fabric web on both sides with a rubber layer, that one the Passes fabric between two rollers, each of which goes through another roller is coated with the plastic compound to be applied before it is applied to the fabric touched. However, this process does not represent friction, but only press-fit of the plastic rubber into the tissue, while friction is caused by rubbing in the Mass in the fabric, as known, is caused by the fact that the fabric between two rollers with unequal peripheral speed passes through.

Isolierband durch doppelseitiges Friktionieren mit Hilfe eines Vierwalzenkalanders herzustellen, soll jedoch Schwierigkeiten bereiten. je nach der Art und der Menge der aufzubringenden Masse sowie je nach Temperatur und der Geschwindigkeit, mit der gefahren werden soll, tritt nämlich eine andere Längung des Gewebes während seines Durchgangs durch die Doppelwalzen ein und damit auch eine verschiedenartige mechanische Beanspruchung des Gewebes. Hierdurch wird verursacht, daß die Gewebebahn, nachdem sie das erste Walzenpaar verlassen hat, nicht mehr glatt in das zweite Walzenpaar einläuft, sondern Blasen und Falten wirft, die in dem zweiten Walzenpaar zerquetscht werden und zu einer Zerstörung des Gewebes führen.Insulating tape through double-sided friction with the help of a four-roll calender manufacture, however, should cause difficulties. depending on the type and quantity the mass to be applied and, depending on the temperature and speed, with that is to be driven, a different elongation of the tissue occurs during its passage through the double rollers and thus also a different one mechanical stress on the tissue. This causes the web of fabric, after it has left the first pair of rollers, no longer smoothly into the second pair of rollers runs in, but throws bubbles and wrinkles, which is crushed in the second pair of rollers and lead to tissue destruction.

Um diesen Nachteil zu vermeiden, wird gemäß der Erfindung an einem üblichen- Vierwalzenkalander eine fünfte Walze E vorgesehen, über welche das Gewebe geführt wird, bevor es zwischen den Walzen D und F hindurchläuft. Die Walze E ist in Pfeilrichtung parallel zu sich selbst frei verschiebbar und wird in dieser Richtung durch eine besondere Kraft, die in der Abb. i durch einen Pfeil dargestellt ist, gegen die Stoffbahn gepreßt, so daß sie in das Walzenpaar D, 1# glatt einläuft.In order to avoid this disadvantage, according to the invention on one usual- four-roll calender a fifth roll E is provided over which the fabric before it passes between rollers D and F. The roller E is can be moved freely in the direction of the arrow parallel to itself and is in this direction by a special force, which is shown in Fig. i by an arrow, pressed against the fabric web so that it runs smoothly into the pair of rollers D, 1 #.

Man hat auch schon früher zu anderen Zwecken zusätzliche Führungswalzen an Kalandern verwendet. Diese Walzen waren aber nicht so frei beweglich gelagert, daß sie die Stoffbahn zwischen dem ersten und dem zweiten Friktionsgang stets gestrafft hielten, welche Ausweitung die Stoffbahn zwischen den beiden Arbeitsgängen auch erfahren möge. In welcher Weise die Walze E gegen die Stoffbahn gepreßt wird, ist an sich für die Erfindung belanglos. In der Abb.2 ist jedoch eine beispielsweise Ausführungsform der Erfindung angegeben. Die Achse der Walze E ist in einer Art Schiebebahn l( zu sich selbst parallel beweglich angeordnet und wird durch das Gewicht L mit Hilfe von Seilen gespannt gehalten.Additional guide rollers have also been used earlier for other purposes used on calenders. However, these rollers were not so freely moveable, that they always tightened the fabric between the first and the second friction gear held, which expansion the length of fabric between the two work steps also may experience. In what way the roller E is pressed against the fabric web is in itself irrelevant for the invention. However, in Figure 2 there is one example Embodiment of the invention specified. The axis of the roller E is in a kind Sliding track l (arranged so that it can move parallel to itself and is driven by the weight L held taut with the help of ropes.
