  • Method for the production of metal closures
    Patent number: 8322177
    Abstract: The present invention relates to a method and tooling suitable for handling closure blanks (5) having an external radius (6) at their cut edge at production speeds of about (1200) closures per minute. The external radius (6) limits formation of “angel hair” (a common problem in metal closure production). However, reversing the external radius causes a problem, when producing metal closures having a conventional inward curl at their peripheral edge. Accordingly, the invention proposes a modified curling rail (40) having a first portion (41) to uncurl the external curl (6) on the closure blank (5) and a second portion (45) to urge the straightened side wall of the closure blank (5) towards an inward curl.
