Abstract (en)
A method of shaping an open end of a metal tube into a flared shape so that the diameter of the tube increases gradually from a point axially displaced from the open end of the tube towards the open end of the tube, the method comprising the steps of using a flanging tool to increase the diameter of the open end of the tube, and the next step of using subsequent forming tool(s) to increase the diameter of the tube at points immediately axially behind the open end of the tube such that the diameter of the open end of the tube remains unchanged from that created in the first step.
