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.
Claims19
A machine for manufacturing a continuous material web, in particular a paper- or cardboard web, comprising:
- a suction roll including a manhole, at least one perforated cylinder sleeve, and an interior surface that defines a roll interior, wherein the roll interior can be put under a vacuum, and wherein the material web is guided on the suction roll;
- a partition wall arranged to divide the roll interior into at least two sections, the partition wall arranged essentially perpendicular to a rotation axis of the suction roll;
- and
- the partition wall, being insertable through the manhole for installation in the roll interior, comprising one of:
- the partition wall constructed of a flexible material sufficiently flexible for insertion through the manhole for installation in the roll interior;
- and
- the partition wall comprising a plurality of sections, said plurality of sections comprising at least one of:
- flexible sections which are insertable through the manhole;
- and
- sections sized for insertion through the manhole.
A drying section for processing a web, comprising:
- at least one suction roll comprising a perforated cylinder sleeve, the at least one suction roll having an interior surface that defines a roll interior, a manhole to provide access to the roll interior, and an axis of rotation, wherein the roll interior can be put under a vacuum;
- a partition wall that divides the roll interior into sections, the partition wall positioned essentially perpendicular to the axis of rotation, wherein the partition wall facilitates a differential vacuum between the sections,
- the partition wall composed of at least one of multiple panel segments and a flexible material insertable through the manhole into the roll interior.
