METHOD FOR FIXING THE POSITION OF A PULL-TAB WITH A STEEP ANTI ROTATION DEVICE FORMED FROM THE PANEL OF A SHEET METAL COVER

摘要

The pull tab position fixing process involves shaping a projection (20) at least twice, first to remove a pre-form of the projection from the can lid, and then to post-form at least one front edge of the projection. Notched lines are not applied. The blocking of the exterior edge section associated with the post-formed front edge is improved.
