Abstract
A method and apparatus for threading a closure which includes securing the closure in a stationary nest, inserting a threading tool having threads on the outside thereof into the interior of the closure, moving the threading tool into contact with the interior portion of the closure upon which threads are to be formed, and moving the threading tool around the interior portion of the stationary closure in an orbital path to form threads in the closure without rotating the threading tool about the threading tool axis.
