Abstract

In a suspension and guidance mechanism for the filter plates of a filter press, where the dollies (1) that carry filter plates (3), each dolly with two rollers (4, 5) that are staggered with respect to each other in the direction of movement and are positioned on two rails (8, 9), and that move along the rails by a transport device located between the running rollers, the derailment of the dollies is prevented in that, laterally, next to the rollers (5) that move in the direction of transport, there is a guide bar (15) or that these rollers (5) have an enlarged wheel flange (16), whereby the height of the guide bar (15) or of the wheel flange (16) is greater than the lifting movements of the roller (5) away from rail (9), caused by plate adhesion during the acceleration of the dollies.
