Abstract

Die Erfindung betrifft eine rotierbare Saugwalze bestehend aus einem perforierten Walzenmantel (1) mit zumindest einer Saugzone (2), die von einer, mit einer Unterdruckquelle (3) verbundenen Saugkammer (4) innerhalb des Walzenmantels (1) gebildet wird, wobei zumindest je ein, zwischen der Saugkammer (4) und der inneren Oberfläche des Walzenmantels (1) angeordnetes Dichtelement (5) die Saugzone (2) wenigstens in Umfangsrichtung (6) begrenzt, die Perforation aus Kanälen (8) besteht und die Kanalmündungen (7) einer äußeren Oberfläche des Walzenmantels (1) möglichst gleichmäßig verteilt und zumindest überwiegend in Umfangsreihen äquidistant angeordnet sind.The invention relates to a rotatable suction roll consisting of a perforated Roller jacket (1) with at least one suction zone (2), one of which, with one Vacuum source (3) connected suction chamber (4) within the roll shell (1) is formed, at least one between the suction chamber (4) and the inner one Surface of the roll shell (1) arranged sealing element (5) the suction zone (2) limited at least in the circumferential direction (6), the perforation consists of channels (8) and the channel openings (7) of an outer surface of the roll shell (1) distributed as evenly as possible and at least predominantly in circumferential rows are arranged equidistant.

Dabei soll die Lärmentwicklung dadurch reduziert werden, dass die Kanäle (8) zumindest einer äquidistanten Umfangsreihe der äußeren Oberfläche des Walzenmantels (1) in Kanalmündungen (9,9',9'') an der inneren Oberfläche des Walzenmantels (1) enden, die in Umfangsrichtung nicht äquidistant angeordnet sind.

Figure 00000001
The noise development is to be reduced in that the channels (8) of at least one equidistant circumferential row of the outer surface of the roll shell (1) end in channel openings (9, 9 ', 9'') on the inner surface of the roll shell (1) are not arranged equidistantly in the circumferential direction.
