Abstract (en)
An apparatus for a paper or board machine, said apparatus including a pressure-tight chamber. The chamber is adapted cross-directionally to the travel of a wire, felt or similar fabric so as to essentially extend over said fabric. The invention is characterized by having the pressure-tight chamber adapted to include a roll (1) with an at least partially permeable shell. The roll shell surface is advantageously formed by a fabric, furthermore, the roll is appropriately free-rotating mounted in bearings at both ends of roll shaft. The invention is further characterized by having the pressure-tight chamber operated with an over- or underpressure relative to the ambient pressure about the chamber. <IMAGE>
