Abstract
A method using high interior pressure to reshape structural section of continuously bounded overall cross-section, whereby the overall cross-section can be provided with extra walls or chambers and a stopper is forced radially against each end of the piece. The object is to reduce wear on the stopper while ensuring that any walls or chambers in addition to its overall crosssection will buckle or bulge only at their ends.
