Appl. No.:

10/650630

Inventors:

Stephen T. Cook - Bellbrook OH, US
Mark F. Broerman - Kettering OH, US
Dale R. Conley - Bellbrook OH, US

Assignee:

Dayton Systems Group, Inc. - Miamisburg OH

International Classification:

B21D 51/38

US Classification:

72334, 72337, 72339, 413 23, 413 56

Abstract:

A method and apparatus for forming container ends includes tooling which forms dome members for can ends, which dome members include an open neck thereon. Thread lugs are formed as integral spaced apart shaped protrusions from the neck exterior. A system is also disclosed for forming quantities of a specific form of dome members, capable of later attachment to container bodies. A thin metal strip is fed through an array of progressive tooling to form blanks, from which such specific form of dome members are formed. The blanks are produced in the metal strip and connected thereto by multiple carrying strips which allow sufficient mobility of the blanks with respect to the strip to achieve precise alignment with the tooling at different stations in the progression. At the final station, completed dome members are separated from the remaining metal skeleton and moved rapidly out of the system, and the skeleton may be chopped up for recycling. Those specific dome members may be attached to a container body in a subsequent operation.

US Classification:

7240513, 72361, 72426, 72428

Abstract:

Transfer apparatus and method are provided from first (A, A) to second (B, B) stations of tooling in a cap () making press. This cap is biased against the first upper tools by a first airstream () introduced under the cap and moves upward with the first station punch (). As the punch approaches its top location, a transfer airstream () begins while the first airstream is still on, and moves the cap out through a transfer chute () to the second station. The cap departs the chute and passes detents () on a pair of closed retention fingers () which define an extension of the transfer path from the chute into the open second station tools. A vacuum () applied to a port in the second station punch then holds the cup against the rising upper tools. When the punch clears the closing fingers and approaches its top location, an ejection airstream () commences to propel the finished cup via a discharge chute ().

Abstract:

Thread lug forming systems form thread lugs () on container necks or necked end domes. A continuously rotating cam system () has multiple sets of thread lug forming tools () which are driven to recirculate about stationary cams (). The cams actuate inner and outer forming tools () 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 (), and the container bodies are indexed through the tool stations () in which the thread lugs are formed.

Abstract:

A resealable can end is provided including a neck () and a cooperating cap member () which can be sealed onto and removed from the neck, and is capable of containing product under pressure or vacuum if desired. This end may be added, by convention seaming methods, such as roll seaming or by appropriate adhesive, to a container body, or may be formed integrally with container bodies. The venting feature of the end will achieve a controlled release of differential internal-to-ambient pressure upon initial opening of the cap, and may also provide resealed containment of partial contents retained in the container, although the contents will no longer be under pressure or vacuum, as the case may be. The end may be applied to, or incorporated in, containers made of various material, such as aluminum, coated steel, or selected plastics.

Abstract:

A system for converting end shells into container ends complete with foil-type tabs covering pour openings formed in the shells utilizes a conveyor comprising at least one continuous belt, or a plurality of such belts operating in parallel, passing around first and second sets of drive drums. The belt(s) are driven intermittently to advance end shells in the nests first through end forming tooling and then through tab forming/attaching and reforming tools One set, or both sets, of the drums are driven to move the belt(s) step-wise along an upper flight, such as to advance the nests in predetermined increments, and a lower return flight. The progressive end conversion tooling for shaping the shells into container ends, with formed and finished pour openings, is located in the mouth or entrance of a press, and the belt(s) passes the nests and shells therein between the upper and lower conversion tooling sets. The tab forming and application tooling is located beyond the conversion tooling but preferably within the boundaries of the mouth of the press. A supply web of foil material is fed step-wise across the conveyor(s) at the beginning of the tab forming and application station and a blanking apparatus at each of the application locations acts to create and to separate (e.g. die cut) tabs from the foil, and tack the tabs against the shells covering the pour openings. The tabs are then heat sealed over the pour opening. The areas around the pour opening=s rolled perimeters, with the foil-tabs attached, then are re-formed to provide a surface sloping slightly downward and away from the pour opening to enhance adhesion of the tabs to the shells in that region, using unique heated tooling
