Abstract

PURPOSE: To make a special pipe with two stream passages, one of which is open or shut according to the pressure difference against the other, by extruding simaltaneously a pipe and a stream bulkhead, which is compressed by air blast to the inner wall of the pipe at a proper point and is bent, forming a shut-off bulkhead.
