Abstract:
A transfer belt assembly (70) includes a plurality of transfer belts (80). The transfer belt assembly (70) is structured to move any of an increased number of shells (3), a very increased number of shells (3), or an extremely increased number of shells (3) through said conversion press (10).)
Abstract:
A can end (30) including a central panel (40) with an expandable bubble (12) disposed thereon is provided. The use of an expandable bubble (12) allows for an expandable rivet button (22) and thereafter an expandable rivet (32) that has an enhanced overlap of a tab body. Such an expandable rivet (32) allows for the use of a metal sheet with a thinner base thickness.
Abstract:
A can closure (20) includes a body (22) with a center panel (30) and a peripheral curl (34). The can closure body (22) has one of a reduced panel depth, a very reduced panel depth, an extremely reduced panel depth, or a beverage can reduced panel depth.
Abstract:
A container can end (10) includes a dome shaped center panel (16), concave on a pull tab (30) mounting side, and may forgo a peripheral reinforcing bead around the center panel. The tab (30) may also be curved. Tooling for forming the end and a corresponding method are provided.
Abstract:
A system and method of orienting the rolling direction of metallic objects is provided. More specifically, the present invention relates to systems and methods used to align the rolling direction of metallic objects in a predetermined orientation in a high speed manufacturing system. The rolling direction is determined by sensing grinding marks on the metallic objects. The metallic objects may subsequently be formed by tools that have been adapted to work with, or transverse to, the rolling direction. Optionally, the tools may form the metallic objects into container end closures adapted to seal a container of a predetermined size and type.
Abstract:
A clamp ring assembly for use in a can bottom forming assembly comprising a clamp ring retainer, a clamp ring having a biasing assembly and an inner dome die. The clamp ring floats with, respect to the clamp ring retainer to accommodate off-center contact by the punch and to center the punch at the end of the ram stroke. A slightly conic-ally shaped inner dome die structure or dome plug may be provided to further center the punch at the end of the ram stroke.
