Metal containers and methods of manufacture

A method of reducing a thickness and increasing a height of a cylindrical wall of a metal cup to form a can body comprises positioning a wall-ironing punch (40) inside the cup, moving an annular wall-ironing die (24) axially over the closed end of the cup towards the open end of the cup, but not beyond the open end of the cup, in order to iron the cylindrical wall from the closed end up to a position axially spaced from the open end and moving the wall-ironing die (24) back in an opposite direction to remove the can body from the die (24). Methods of altering a diameter of one or more regions of a can body are also disclosed.

CAN BODY MANUFACTURING SYSTEM

While deterioration in processing efficiency caused by printing devices with slow printing speed is suppressed, facilities necessary to manufacture can bodies are able to be shared. A can body manufacturing system includes: a can body conveyance route, by which can bodies are conveyed, provided to branch halfway and thereafter merge again, the can body conveyance route at least including a first branching conveyance route and a second branching conveyance route; a first printing device performing printing on can bodies conveyed by the first branching conveyance route; and a second printing device performing printing on can bodies conveyed by the second branching conveyance route, the number of can bodies on which printing is performed by the second printing device per unit time being different from the number of can bodies on which printing is performed by the first printing device per unit time.

Can bodymaker

A can bodymaker, which includes a disc feed (1) for feeding a disc (5) directly to the bodymaker itself. A locator (9) positions the disc (5) centrally to a blankholder (12) and a draw pad (10) clamps the disc (5) against a draw die (11). The blankholder (12) then forms the disc into a cup (20) and clamps the cup against a redraw die (14) ready to be picked up by a punch and carried through dies for forming a can body.

10976263 · 2021-04-13 · ·

An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration on a predetermined portion of a metallic container body. The decorator includes a sensor that senses decorations on metallic containers. A control system receives information related to the sensed decorations from the sensor and then determines if the decorations at least meet predetermined color, density, thickness, orientation, and consistency targets. The control system can automatically adjust elements of the decorator to correct a deficient decoration. In one embodiment, the control system can automatically adjust ink blades associated with a plurality of inking assemblies of the decorator to adjust the color, density, orientation, positioning, and consistency of decorations transferred to the metallic containers. In another embodiment, the control system can adjust a position of an inking assembly, an ink roller, a plate cylinder, a printing plate, a blanket cylinder, and a transfer blanket of the decorator.
