    • A filter press with central suspension of filter plates (5) is provided with a guide which ensures a flush alignment of adjacent filter plates, said guide lying outside the area affected by the filter medium, being integrated in a space-saving manner into the filter press, and permitting a certain amount of twisting or other overall adjustment of the filter plate package. For this purpose, the guide device is disposed on the filter plate suspension (9, 10, 18, 25) and is composed of at least one guide rod (19, 20) which is flexible to a limited elastic degree, and runs along guide members (1,2), and of at least one guide element (21, 22) for each filter plate (5) fitting around guide rod (19, 20), said elements being disposed on yoke piece (25) which supports rollers (19, 10) of the filter plate suspension.
