Claim 11:
12. A method of sealing an open end of a threaded metallic bottle with a closure, comprising:
providing a capping apparatus having a pressure block ejector and a thread roller;
positioning the closure on a threaded neck of the threaded metallic bottle;
applying a first topload by the pressure block ejector to an exterior surface of a top portion of the closure to seal the threaded metallic bottle;
while the first topload is applied to the closure, forming threads on the closure with the thread roller by at least a first pass and a second pass of the thread roller; and
after at least partially forming the threads on the closure, rotating at least one of the closure and the threaded metallic bottle around a longitudinal axis of the threaded metallic bottle such that an uppermost portion of the open end of the threaded metallic bottle is moved closer to the exterior surface of the top portion of the closure, wherein the rotating occurs after the first pass of the thread roller and before the second pass of the thread roller when the threads are partially formed.
