摘要

Apparatus for the continuous filtration of contaminated moulding compound (melt) plasticated in an extruder (1), having a filter screen (11) which is arranged downstream of the extruder and holds back the impurities, a stripping device, by which a filter cake formed on the filter screen (11) by the impurities is removed, and an outflow path (21) for the removed filter cake which is separate from an outflow path (12, 13, 14) of the filtered melt, the stripping device being formed by a further extruder (filter extruder 15). <IMAGE>
