Abstract

Die Erfindung betrifft eine Saugeinrichtung, insbesondere Saugkasten (21) oder Saugwalze für eine Maschine zum Herstellen oder Verarbeiten von Faserstoffbahnen, beispielsweise Papierbahnen, mit den folgenden Merkmalen:

  • a) die Saugeinrichtung (21) erstreckt sich quer zur Bahnlaufrichtung über die Breite der Bahn und hat eine Vielzahl von über die Bahnbreite verteilten Saugöffnungen (26,27), die an eine Vakuumquelle (32,32A,32B) anschließbar sind und deren Gesamtheit eine sich über die Bahnbreite erstreckende Gesamtsaugzone bildet;
  • b) dadurch gekennzeichnet, daß die Gesamtsaugzone in eine Vielzahl von Teilsaugzonen (55a) unterteilt ist, die quer zur Bahnlaufrichtung hintereinander liegen und die, beginnend an einem der beiden Enden der Saugeinrichtung, nacheinander an die Vakuumquelle (32 oder 32A,32B) anschließbar sind.

    The invention relates to a suction device, in particular a suction box (21) or suction roller for a machine for producing or processing fibrous webs, for example paper webs, with the following features:
  • a) the suction device (21) extends transversely to the web running direction over the width of the web and has a plurality of suction openings (26, 27) distributed over the web width, which can be connected to a vacuum source (32, 32A, 32B) and the entirety of which is one total suction zone extends across the web width;
  • b) characterized in that the total suction zone is subdivided into a plurality of partial suction zones (55a) which lie one behind the other transversely to the web running direction and which can be connected successively to the vacuum source (32 or 32A, 32B), starting at one of the two ends of the suction device .
