Apparatus for filtering a stream of plasticized synthetic plastic material in an extruder has a housing with four or more channels connecting a material-admitting inlet with a material-discharging outlet. The housing is formed with parallel bores each of which receives a single reciprocable cylindrical carrier of two or more filters or two independently reciprocable cylindrical carriers of discrete filters. Each carrier can be moved between a first position in which its filter or filters register with discrete channels of the housing and at least one add...
Apparatus for filtering a flowable synthetic plastic material in an extruder, comprising a housing having an inlet and an outlet for a stream of plastic material and at least four discrete channels connecting said inlet with said outlet; a plurality of carriers mounted in and movable relative to said housing between a plurality of different positions, each of said carriers having at least one passage which is in register with one of said discrete channels of said housing in one position of the respective carrier and is accessible in another position of t...
