摘要

An ironing stamp is configured with a singular conformation, having a pilot part integral, so that it supports the die and the can during the critical phase of the ironing on the uneven edge, thus resulting in a wall of more uniform thickness in the transition to the uneven edge as well as the longest part of the edge itself. By accurately and effectively controlling the thickness of the long edge at all stages, i.e., re-embossing, first, second and third ironing stamps, the tears and cuts are virtually eliminated.
