Description

Vorrichtung zum Dehnen oder Stauchen der Maschen der Entwässerungsfilze in Naßpressen von Papier- und Entwässerungsmaschinen. Damit die Entwässerungsfilze eine lange Laufdauer erreichen, ist es erforderlich, daß die Filzmaschen, die sich durch starkes Spannen zusammengeschlossen haben, zeitweise wieder geöffnet werden. Man muß das Filzgewebe nach jeder Richtung hin nach Belieben sofort verziehen können. Dadurch erzielt man, daß der Filz die Papierbahn stark und gleichmäßig entwässert. Der Filz selbst wird nicht so schnell verschmutzt und erhält infolgedessen eine lange Laufdauer.Device for stretching or compressing the meshes of the drainage felts in wet presses of paper and dewatering machines. So that the drainage felts To achieve a long running time, it is necessary that the felt mesh, which is have closed together due to strong tensioning, are temporarily opened again. One must be able to warp the felt fabric immediately in any direction as desired. This ensures that the felt drains the paper web strongly and evenly. The felt itself does not get dirty as quickly and consequently gets a long running time.

Zu diesem Zweck sind gemäß der Erfindung vor oder hinter der Presse a, b zwei Walzen c und d in einem gemeinsamen, dreh- und in Achsenrichtung verschiebbaren Lager i auf einer ortsfesten Welle k angeordnet. Die Walze c besitzt in der Mitte einen etwas stärkeren Durchmesser als ihre beiden Enden. Bei der Walze d dagegen besitzen die beiden Enden einen stärkeren Durchmesser als die Walzenmitte. Sobald der Filz g in der Mitte zurückbleibt, können die beiden Walzen c und d durch einen Hebel f in Richtung gegen den Filz verstellt werden.For this purpose, according to the invention, two rollers c and d are arranged in front of or behind the press a, b in a common, rotatable and axially displaceable bearing i on a stationary shaft k. The roller c has a slightly larger diameter in the middle than its two ends. In the case of roller d, on the other hand, the two ends have a larger diameter than the center of the roller. As soon as the felt g remains in the middle, the two rollers c and d can be adjusted by a lever f in the direction against the felt.

Legt sich bei dieser Verstellung die ballige Walze c mehr in den Filz hinein, so wird der Filz g in der Mitte mehr vorgezogen. Das Gegenteil tritt ein, wenn die ausgehöhlte Walze d gegen den Filz mehr angestellt wird. Wenn z. B. die Ränder des Filzes g vorgeholt werden sollen und die Mitte gegen diese zurückbleiben soll,,dann werden die Walzen c und d durch Schwenken des Hebels f um die Welle k- in der Pfeilrichtung j verstellt. Das entgegengesetzte Ergebnis wird erzielt beim Schwenken des Hebels f in der Pfeilrichtung h.If, during this adjustment, the spherical roller c lies more into the felt, then the felt g is pulled forward more in the middle. The opposite occurs when the hollowed-out roller d is made more against the felt. If z. B. the edges of the felt g should be brought forward and the center should remain against this, then the rollers c and d are adjusted by pivoting the lever f about the shaft k- in the direction of arrow j. The opposite result is achieved when the lever f is pivoted in the direction of the arrow h.

Ist der Filz nicht verzogen, dann können die beiden Walzen c und d. übereinandergelagert bleiben. Das Regeln des Filzes g erfolgt dann vom Zapfen der Preßwalze b aus, an den exzentrisch der Bolzen L der am Lager i angreifenden Exzenterstange e angreift. Dadurch werden die Walzen c und d stetig in Richtung gegen den Filz hin und her bewegt.If the felt is not warped, then the two rollers c and d. remain superimposed. The regulation of the felt g then takes place from the journal of the press roll b, which is eccentrically engaged by the bolt L of the eccentric rod e acting on the bearing i . As a result, the rollers c and d are continuously moved back and forth in the direction against the felt.
