Abstract
The apparatus forms an elongate tubular member into a predetermined shape while preventing crimping of the walls of the member and comprises jaws for holding the member at its opposing ends and a pressurizer for pressurizing the interior of the member to a predetermined pressure greater than atmospheric pressure while being held sufficient to provide increased effective regidity and crimp resistance to the walls of the member. A die exerts a force against the member sufficient to form the member into a predetermined shape while pressurized. The pressure within the member is released after the member has been formed into its desired shape.
