A simplified screen changer is provided which is particularly suitable for the extrusion of synthetic resinous thermoplastics. Screens are supported in a recessed movable plate. The screen on the upstream side is sealed against leakage by means of an extrusion pressure actuated sealing ring. The apparatus is of simple and rugged construction.


A screen changing apparatus, particularly suited and adapted for use in the extrusion of heat-plastified synthetic resinous extrudable material, the apparatus comprising a conduit, the conduit having an upstream end and a downstream end, and a passage therebetween, a plate-like element slidably disposed within the conduit and extending transversely to the passage, first and second recesses defined in the plate-like element, the plate-like element being in sliding engagement with the conduit toward the dowstream end, and when forced toward the downstream ...
