发明名称 Device at presses for dewatering materials
摘要 This invention relates to a device at presses for dewatering materials such as peat, digested sludge and other fiber material, which device comprises a belt, which in cooperation with at least one press roll is arranged to apply a press pressure to a material introduced between belt an roll. Certain problems exist here in achieving a high and evenly distributed press pressure over the whole belt width, but this and other problems are solved according to the invention in such a way that the belt consists of a number of separate belt elements (19) located beside each other, each with a cross sectional form decreasing from the side (20) facing the material and with edge portions (23) being in contact with each other, which portions are so elastic that they are opened by the material exposed to the press pressure for discharge of water pressed out of the material.
