Abstract
A tube has a longitudinal slot extending over the entire working width of the apparatus, and at least one cover element is arranged on the side of the fabric web remote from the slotted tube. The cover element extends over the entire length of the slot, and also extends over a substantial portion of the path of the fabric web, immediately preceding the slot, and over another substantial portion of the path of the fabric web immediately following the slot. A guide surface for the fabric web is provided on the same side of the web as the slotted tube, which surface forms with the cover element a flow space for conducting the working fluid, which flow space extends from a point in the path of travel of the fabric web lying substantially ahead of the slot to a point in the path of the web lying substantially beyond the slot.
