Apparatus for filtering plasticized material between two discrete inlets and a main outlet of a housing has two passages each of which connects one of the inlets with the main outlet. Each passage receives a reciprocable cylindrical filter carrier which can establish or interrupt a path for the flow of plasticized material from the respective inlet to the main outlet, depending on the selected axial position of the carrier. In order to expel contaminants which gather at the upstream side of the filter in a carrier, the carrier which is to be relieved of ...
