movement which is directed counter to the movement of the roll jacket surface 1 a the liquid usually water present on the roll jacket surface 1 a will then combine with the water which is being conveyed at high kinetic energy after which they jointly rebound from the flexible roll jacket surface towards the lip element 26 from the lip element 26 the water is conveyed towards the mouth 24 of the container device 22 by means of the latter being under vacuum the water is then led off from the container via its outlet 23 the arrangement thus permits rapid and effective removal of water from the roll jacket surface 1 a and at the same time if necessary cleaning thereof the method is particularly effective in connection with patterned roll jacket surfaces which cannot always be dewatered or cleaned sufficiently well by current methods in addition the method has the great advantage that there does not need to be any direct physical contact between the roll jacket surface and the device for removing water which fact minimizes the risks of wear and risks of damage which exist when a flexible roll jacket is in direct contact with any device given that these flexible roll jackets are expensive this is a not inconsiderable advantage by means of the device according to the invention a press section is also obtained which includes the device according to the invention the invention is not limited by what has been described above and instead it can be varied within the scope of the attached patent claims it will be appreciated that among other things the lip.
