Apparatus for degassing thermoplastic synthetic plastics material

Apparatus for degassing thermoplastic synthetics material, which is supplied through at least one inlet opening (12) into a housing (10) of a first screw section (11), at the end of which the plasticized synthetic plastics material is pressed into at least one connection channel (15) in which at least one filter (16) for the synthetic plastics material is disposed, the synthetic plastics material after having passed this filter streams to an inflow opening (17) of a housing (18) of a second screw section (19) which is disposed coaxially to the first screw section (11) and conveys a synthetic plastics material along a degassing region provided with at least one degassing opening (20) to an outlet opening (21), a sealing section (26) being interposed between the two screw sections (11, 19) which avoids bypassing of the connection channel (15), the two screw sections (11, 19) and the sealing section (26) being bearingly supported within bores (40, 41) of the housings (10, 18) having equal diameters, within the housing (18) of the second screw section (19), at least one baffle member (28) for the flowing synthetic plastics material being provided between the inflow opening (17) and the degassing openings (20), the baffle member (28) forcing the synthetic plastics material flow into a hose-formed shape and being adjustable with respect to the inflow opening (17), the baffle member (28) being disposed so in front of the inflow opening (17) that the synthetic plastics material streaming from the inflow opening (17) into the housing (18) of the second screw section (19) hits directly the periphery of the baffle member (28) which is disposed axially spaced apart from the nearest degassing opening (20) and has a cross section tapering towards the second screw section (19).
