ABSTRACT:
Reform rollers for use in internal or external base reforming of can bodies have a textured surface which control the depth of the dome of the can base and provide greater process stability than is achieved with known smooth rollers. One example of textured surface finish provided by spark erosion has been shown to have much greater consistency of dome reversal pressure, dome growth and dome depth.
