Abstract

The steam distributor (1) for the application of steam to a material web (3) such as paper features a main distribution space (9). This is subdivided into a multiplicity of chambers (24), all of which have a steam valve (21). The median lines of the associated discharge openings (35, 36) form an angle of at least 60 DEG with an axis which stands vertically on a housing wall (2) with vents (8). At least twelve such vents (35, 36) are provided. This leads to very uniform distribution of the steam within the chamber and thus to uniform steaming of the material web below this chamber. <IMAGE>
