Abstract

A machine for manufacturing a continuous material web, in particular a paper or cardboard web, with at least one perforated cylinder sleeve and a suction roll exhibiting a manhole around which the material web is guided preferably with the aid of a transport band, whereby the interior of the suction roll can be put under a vacuum and is subdivided into at least two sections by a partition wall that is arranged essentially perpendicular to the rotation axis of the suction roll, wherein the partition wall is subdivided into sections and/or is manufactured of a flexible material and can thereby be inserted through the manhole and into the roll interior.
