Abstract (en)

Method for cleaning the surface (16) of a moving web of paper comprises spraying it with cleaning fluid under pressure. The mixture of air, soiling and fluid produced is passed through a collector (4) where the soiling is deposited. The collector is cyclically cleaned. An independent claim is included for apparatus for carrying out the method which incorporates a spray (2) and a collector cleaning unit.

Abstract (de)

Bei einem Verfahren zum Reinigen einer Oberfläche (16) vorzugsweise eines sich bewegenden Bandes (16) wird die Oberfläche mit mindestens einem Strahl eines unter Druck stehenden Reinigungsfluids beaufschlagt. Hierdurch werden auf der Oberfläche (16) des Bandes anhaftende Verschmutzungen gelöst und ein von dem Band weggerichteter Strom einer Mischung aus Umgebungsluft, dem Reinigungsfluid und den von dem Band abgelösten partikelförmigen Verschmutzungen erzeugt. Um auf effiziente Wese zu vermieden, dass die abgelösten Verschmutzungen sich an anderer Stelle bzw. auf dem Band niederschlagen, sondern aus dem Strom der Mischung herausgetiennt werden, wird vorgeschlagen, dass der Strom der Mischung durch einen Kollektor (4) hindurch oder an einem Kollektor (4) entlang geleitet wird, an dessen Kollektorflächen sich zumindest die Verschmutzungen anlagern und während eines Zeitraums kumulieren, wobei die Verschmutzungen von den Kollektorflächen zyklisch abgereinigt werden.
