Inside the holding ring (), a curl roller () and a tightening roller () are mounted opposite to each other. The holding ring () is so mounted on a guide ring () as to be turned via a pressurization roller (). The guide ring () is drive-controlled in the X-axis direction and Y-axis direction by an X-axis table () and a Y-axis table () driven by servo motors () according to the shape of a can.
