Rolling method and apparatus using planetary cross-rolls
 A rolling method and apparatus permits a long metal blank to be rolled across the width thereof at a high rolling speed. According to one specific embodiment of the method and apparatus, a sun roller is mounted to a machine stand, and a set of planetary rollers is mounted for rolling movement around the sun roller. The long metal blank is rolled between the sun roller and the set of planetary rollers by feeding it in the direction of the center line axes through the sun roller and the set of planetary rollers. The method and apparatus provide a planetary cross-rolling process that may proceed in a successive manner. According to another specific embodiment of the method and apparatus, a sun roller is rotatably mounted to a machine stand, and a set of planetary rollers is mounted for engaging and rolling around the sun roller. A back-up housing is mounted to the machine stand and is also mounted around the set of planetary rollers. A long metal blank is rolled between the set of planetary rollers and the back-up housing by feeding it in the direction of the center line axes through the set of planetary rollers. Both of the above embodiments feature the planetary cross-rolling process.
