pressurization for example an overpressure may be formed via air pressure in a first chamber in an adjacent second chamber a partial vacuum may be formed to suction off water or moisture in a next adjacent third chamber another over pressure etc through press device 20 as an alternative enhancement to this embodiment rinse water may be utilized to create or form the over pressure in this manner a particular rinsing effect may further be produced however this rinsing effect will accordingly reduce the draining capacity of the machine further pressure element 21 may create or generate pressure pulses to further improve the draining capacity in principle the process of the present invention may be performed if at least one of the converging surfaces is arched as illustrated in fig9 an arched surface which is generally the surface that is driven to move interacts with a flat surface to provide the above discussed two sided draining in a manner similar to fig8 fig1 illustrates a draining area that utilizes pressure rails 24 pressure rails 24 may be pressed e g with springs against an interior of a permeable surface of the inner arched surface it is noted that this additional pressure may further enhance the draining due to wear considerations pressure rails 24 are preferably utilized in conjunction with the.
