ABSTRACT:
A conversion system for converting plain container end pieces into easy-open end pieces in a single press includes multiple slides, all driven by the press and carried within the confines of the press frame but independently adjustable and controllable. At least one of the slides carries conversion tooling and the other carries tab forming tooling and is arranged adjacent the conversion tooling so that the tab strip may be fed into the conversion tooling for attachment of the tabs to the end pieces by the conversion tooling. High speed feed rolls having helical gripping grooves are also provided to feed plain end pieces to the conversion tooling for forming and for attachment of the tabs.
