ABSTRACT:
Continuous-strip process for improving ironing operations in the manufacture of drawn and ironed container bodies having a bottom wall and unitary sidewall. Strip surfaces are treated, in final cold reduction operations for flat rolled container stock, to produce sculptured surfaces with fine line impressions to hold lubricant on the exterior surface of the sidewall during ironing and to reduce intimate surface contact with the ironing mandrel on the interior surface. Electroplated protective coatings are not reflowed in order to maintain the surface indentations.
