Abstract

Thread lug forming systems form thread lugs (36) on container necks or necked end domes. A continuously rotating cam system (100) has multiple sets of thread lug forming tools (135) which are driven to recirculate about stationary cams (130). The cams actuate inner and outer forming tools (150, 152) of the tool sets as they progress around the cams to form the thread lugs. A second system uses generally the same tool sets in a multiple-station reciprocating press (203), and the container bodies are indexed through the tool stations (252) in which the thread lugs are formed.
