The principles of the present invention further provide both a shaped metal container and its preforms that exhibit a rounded grain structure characteristic created by an annealing process and a method for making a shaped metal container. The process of making said metal container results in a quicker process time and uses less metals (at least 10% metal weight savings), thus allowing for a decrease in the costs of making such shaped metal containers. A shaped metal container may include work hardened rolled sheet-metal defining a sidewall, an opening, and a base, where at least one section along the sidewall has grains with an average aspect ratio less than about 4 to 1.

A can bodymaker includes a mounting assembly and a forming system. The forming system includes a plurality of forming assemblies, each forming assembly coupled to the mounting assembly, each forming assembly including a ram assembly with an elongated ram body, and a ram drive assembly operatively coupled to each forming assembly. The ram drive assembly is a direct ram drive assembly.

Methods and apparatus of decorating metallic containers are provided. More specifically, the present invention provides novel apparatus and methods of forming an indicia or a decorative shape on a closed end-wall of a metallic container body. A tool of one embodiment of the present invention is operable to form an indicia in a metallic sheet. A cupping apparatus can subsequently form a cup from the metallic sheet which includes the indicia. The cup can be formed into a container body by a bodymaker. In another embodiment, a tool of a bodymaker is operable to form an indicia or a decorative shape in a closed end-wall during formation of a metallic container body. The indicia or decorative shape can be formed by coining, punching, embossing, debossing, and other techniques of forming and shaping metal material from which the metallic container body is formed. In this manner, the indicia may include one or more raised portions and sunken portions in the closed end-wall. Optionally, the indicia may enhance the strength of the closed end-wall, such as to prevent or resist buckling and deformation.

A lubricator 2 supplies an unwound coil material as an alloy plate material 11 to a metal beverage can production line for forming the alloy plate material 11 into a metal beverage can. The lubricator 2 includes: a felt roll 21 configured to contain lubricating oil in a first outer circumferential section, a felt roll 22 with a second outer circumferential section, a plate material lift configured to switch between a first state in which the alloy plate material 11 contacts the first outer circumferential section of the felt roll 21 and the second outer circumferential section of the felt roll 22, and the first outer circumferential section and/or the second outer circumferential section apply the lubricating oil to the alloy plate material 11, and a second state in which the felt roll 21 and/or the felt roll 22 applying the lubricating oil in the first state are idly rotatable by separating from the alloy plate material 11, and an air receiving section configured to apply a driving force to the idly rotatable felt roll 21 and/or the idly rotatable felt roll 22 in the second state as switched by the plate material lift.
