Separator screen and method of making same.

摘要

A screening device having an inflatable screen frame (14) and a rigid screen frame member (28). The frame assembly expands with inflation in a self-controlled manner to tension the associated screen cloth (30) and to fix the frame within the screening device. A method of making screen assemblies uses heated screen cloth to fuse the frame thereto. Heating is accomplished by concentrically arranged electrodes (52, 54).
