ABSTRACT:
The present invention relates to a method for removing water from a movable roll jacket surface in a wet section of a paper-making machine, which roll jacket surface preferably belongs to a flexible roll jacket in a shoe press, said method comprising the following steps: arranging a spray device next to the roll jacket surface, making available a collecting device which is provided with an opening and collects liquid, moving said roll jacket surface past said spray device, applying a medium onto said roll jacket surface with the aid of said spray device, and collecting liquid in said liquid-collecting device. The invention is characterized in that said medium is sprayed with high kinetic energy onto said roll jacket surface to follow a fluid stream rebounding from the roll jacket surface, so that the liquid is conveyed to said liquid-collecting device.
