ABSTRACT:
A device for filtering a fluid, particularly a molten plastic, with a fluid-supplying canal and a fluid-draining canal is described, whereby two plate-like filters are movably arranged in and across the flow direction of the fluid to be filtered between the fluid-supplying canal and the fluid-draining canal. Hereby the fluid-supplying canal (4) is connected with the fluid-draining canal (5) by a single connecting canal (6). This single connecting canal (6) comprises a funnel-shaped extension (13) taking up the at least two filters (7, 8), whereby the at least two filters (7, 8) are simultaneously movable between a first position in which the at least two filters (7, 8) filter the fluid and a second position in which at least one filter (7; 8) of the at least two filters (7, 8) is superfused in the opposite flow direction (14) of the fluid during the filtering process, whereas the other filter (7; 8), respectively the other filters, filters, respectively filter, the fluid, whereby in this second position of the at least two filters (7, 8) the fluid can be drained out of the device into the atmosphere.
