METHOD OF AND APPARATUS FOR FORMING A CLOSURE |
摘要 |
A method and apparatus for forming a closure in which the closure includes a peelable panel with integral tab folded over the panel. The apparatus includes upper and lower reform tools, the upper reform tool having a tab relief feature and local scallops at each end of the tab relief. When reform tools move together for reforming, the tab relief feature is positioned over the tab fold and the scallops at the ends of the fold. As a result crushing and fracture of the tab during reforming is avoided.
