Abstract
The invention relates to a machine for pressing or dewatering and filtering of suspensions, sludges and the like with at least one driven endless pressure belt and further in particular at least one circulating endless filter belt, the pressure belt serving for the support of the filter belt. For the exertion of surface pressure onto the pressure belt, at least one frame-like, resilient, elastic hollow pad or a resilient, elastic hollow frame is provided, their interior being suitable for the admission of pressure medium and the pad or frame enclosing a pressure space, with a gap being provided at least during the admission of pressure medium between the hollow pad or hollow frame and the pressure belt.
