A screening apparatus for molten plastic material flowing from an extruder comprising a housing mounted on the extruder and having a feed channel for flow of the plastic material therefrom and a slide member mounted for slidable movement in the housing with a clearance therebetween. The slide member contains replaceable screen elements adapted for being positioned in the path of flow of the plastic material flowing from the extruder to effect screening thereof. In order to seal the clearance between the slide member and the housing to prevent outflow of ...
