Abstract: A method and apparatus for providing a contoured design confirguration in the wall of an open ended container workpiece employs plural molds on a rotating turret an which a plurality of molds are provided with each mold having an inwardly facing wall having the desired configuration. The workpiece is delivered from a pneumatic conveyor and vacuum star wheel into an open mold which then closes and the interior of the workpiece is pressurized with air. A rotary wand moves into the workpiece and discharges high velocity rotating liquid jets against the inner wall surface of the workpiece to forcefully move the wall outwardly into conforming contact with the inner wall surface of the mold to effect permanent reshaping of the workpiece into the desired configuration.
