Abstract
In seaming various shapes of cans, there is no need of replacement of a profiling cam or experience in techniques, thus enabling to reduce the number of components to be replaced and simplify a replacement work remarkably. Below a rotary driving ring (), a holding ring () is mounted in such a manner that it can move horizontally and rotate integrally. 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.
