Abstract:
A rolling machine for processing a metal container which has a longitudinal seam and is made from a flat metal plate to form a cylindrical body having adjacent or overlapping butt edges securely joined to one another by folding or welding, whereupon a disk-shaped lower bottom and, optionally, a respective upper bottom, is welded or folded to the cylindrical body to form a closed container, or an open-topped container, respectively, with the adjacent or overlapping butt edges of the cylindrical body being subject to a rolling process over an entire length of the cylindrical body in the area of the longitudinal folding seam or longitudinal welding seam after the folding process or welding process and prior to the attachment of the at least lower bottom, said rolling machine being configured as a continuous rolling machine and comprising an upper carrier frame; an upper rolling drum rotatably supported in the upper carrier frame; a lower drum stand; and a driven lower rolling drum rotatably mounted in the lower drum stand; and a central first locking device and a second locking device positioned at opposite axial ends of the rolling machine, wherein the upper carrier frame is provided for acting on an inside surface of the body and is supported in a floating manner by alternating an engagement of the first and second locking devices.
