Apparatus for threading cans

摘要

A threading head includes a threading head and a container holder. The threading head includes a first threading roller with a threaded surface and a second threading roller with a threaded surface. The container holder is mounted on the threading head with a rigidly held rotation arm so that a container held within the container holder is non-rotatable. The container holder is configured to apply a gripping force to grip the container and is configured to remove the gripping force to release the container. The container holder holds the container proximate an open end of the container.
