Abstract

In einer Vorrichtung zur Behandlung der Materialbahn 14 wie insbesondere einer Papier- oder Kartonbahn ist die Materialbahn 14 über wenigstens eine insbesondere glatte Stützfläche 22 und anschließend zusammen mit einem porösen Stützband 16 zu einer Umlenkwalze 18 oder dergleichen geführt, wobei die von der Stützfläche 22 ablaufende Materialbahn 14 mittels einer Unterdruckzone 24 an das poröse Stützband 16 ansaugbar ist, die an die von der Materialbahn 14 abgewandte Seite des porösen Stützbandes 16 angrenzt und zwischen diesem und einer gegenüberliegenden Wand 26 eines Saugkastens 20 definiert sowie an ihrem in Bahnlaufrichtung L vorderen Ende durch wenigstens ein mit dem Stützband 16 zusammenwirkendes Dichtelement 28 abgedichtet ist und sich mit ihrem hinteren Ende zumindest im wesentlichen bis zur Umlenkwalze 18 erstreckt. Die Saugkastenwand 26 ist mit einer insbesondere schlitzartigen ersten Saugöffnung 32 versehen, die im Bereich des der Umlenkwalze 18 benachbarten hinteren Endes der Unterdruckzone 24 angeordnet und durch die hindurch Luft aus der Unterdruckzone 24 absaugbar ist. Die Saugkastenwand 26 ist mit wenigstens einer weiteren in die zusammenhängende Unterdruckzone 24 mündenden Saugöffnung 34 versehen.

In a device for treating the material web 14, such as in particular a paper or cardboard web, the material web 14 is guided via at least one in particular smooth support surface 22 and then together with a porous support belt 16 to a deflection roller 18 or the like, the material web running off the support surface 22 14 can be sucked onto the porous support belt 16 by means of a vacuum zone 24, which adjoins the side of the porous support belt 16 facing away from the material web 14 and defines between this and an opposite wall 26 of a suction box 20 and at its front end in the web running direction L by at least one is sealed with the support band 16 cooperating sealing element 28 and extends with its rear end at least substantially to the deflection roller 18. The suction box wall 26 is provided with a slot-like first suction opening 32 in particular, which is arranged in the region of the rear end of the vacuum zone 24 adjacent to the deflection roller 18 and through which air can be extracted from the vacuum zone 24. The suction box wall 26 is provided with at least one further suction opening 34 opening into the connected vacuum zone 24.
