    Abstract: A method and apparatus for mechanically reshaping and/or forming textured features in the side wall of metal can bodies in which a can body is mounted on a profiled mandrel and rolled along a second mandrel or rail, which is also profiled. The tools are made from hard material but the second mandrel or rail is resiliently mounted. This mounting has been found to facilitate control of the depth of the profiled features formed in the can body. In particular, the problem of depth variability which will arise due to expansion of the machine and tooling in normal running conditions, or variability in thicknesses in the can body is avoided. Typically, the can body is clamped between complementary unformed regions on the tools during forming so as to prevent wrinkling or localised thinning of the can side wall.

    Abstract translation: 一种用于在金属罐体的侧壁中机械整形和/或形成纹理特征的方法和装置，其中罐体安装在成型心轴上并沿着也被成型的第二心轴或轨道滚动。 这些工具由硬质材料制成，但是第二芯棒或导轨是弹性安装的。 已经发现这种安装便于控制形成在罐体中的成型特征的深度。 特别地，避免了由于机器在正常运行条件下的膨胀而引起的深度变异性问题，或罐体中的厚度变化的问题。 通常，罐体在成型期间夹在工具上的互补未成形区域之间，以防止罐侧壁起皱或局部变薄。

    Abstract: A method for manufacture of a metal can body is described in which two or more stretching operations are used so as to reduce the thickness of the central part of a cup base, prior to drawing the cup sidewall and forming a can body. By using two or more stretching operations, it has been found possible to control the thickness of the base without significantly reducing pressure performance of the finished can. Alternative embodiments of apparatus comprising tooling for carrying out this method are also described.

    Abstract translation: 描述了一种用于制造金属罐体的方法，其中在拉拔杯侧壁并形成罐体之前，使用两个或多个拉伸操作以便减小杯形基座的中心部分的厚度。 通过使用两个以上的拉伸操作，已经发现可以在不显着降低成品罐的压力性能的情况下控制基材的厚度。 还描述了包括用于执行该方法的工具的装置的替代实施例。
