Abstract:
A can end is provided, which includes a severable panel, a peripheral scoreline defining the periphery of the severable panel, an opening mechanism such as a pull tab, a rivet coupling the pull tab to the severable panel, and a rivet base scoreline in the public side of the severable panel within about 0.025 inch or less of the stem of the rivet. The rivet base scoreline includes an arcuate head portion, first and second arm portions extending from the arcuate head portion, and first and second ends. The base of the rivet has a radius of curvature forming an intersection between the stem of the rivet and the public side of the severable panel. The arcuate head portion of the rivet base scoreline is contiguous with the radius of curvature. The pull tab includes a nose portion having a number of apertures aligned with corresponding portions of the rivet base scoreline disposed thereunder.
Abstract:
A modular tooling system for use in combination with a conversion press has an upper base member adapted to be removably mounting into the conversion press, a tooling holder, a tooling insert and means for retaining the tooling insert within the tooling holder. The tooling holder is adapted for attachment to the upper base member. The tooling holder defines a chamber therein extending therethrough. The chamber includes a shoulder portion. The tooling insert is adapted to be removably mounted in the tool holder. The insert has a first end, a second end, and a shoulder portion adapted to cooperate with the tooling holder shoulder portion. Bushings and spacers secure the insert within the tooling holder. Both the tooling holder chamber and the tooling insert are of a predetermined cross section which are adapted to correspond with each other and define a keyed relationship.
Abstract:
A non-circular can end for a container having walls which form an opening includes a corner-mounted pull tab opener secured to a severable panel portion by an integral rivet. The corner-mounted opener facilitates easy opening of the can end. A pair of generally parallel bead recesses on either side of the integral rivet stiffen the severable panel portion in order to facilitate bending of the panel aft of the rivet to easily open the can end. The severable panel optionally further includes a mustache-shaped scoreline to reduce the amount of force required to lift the opener. Tooling and a conversion press for converting shells into the non-circular can ends are also disclosed.

Abstract:
The disclosed and claimed compresses gas system provides for the use of a rotary valve assembly in association with a cupper. A compressed gas system that utilizes a rotary valve assembly uses less gas than a constant flow compressed gas system and is quieter than a compressed gas system that uses valves. The rotary valve is a disk-like body having an opening therethrough. The rotary valve body is disposed within a housing assembly wherein gas may only flow through the housing when the rotary valve body is properly aligned with a space on one side of the rotary valve body.
Abstract:
A die tool monitor and analysis system identifies tooling changes and maintains tooling in an optimal position, thus maintaining the quality of the manufactured product within a desired tolerance band. A die tool force monitor and analysis system identifies changes in the operational conditions within a press. These identified changes are indicative of tooling changes and in conjunction with a thermal control system, facilitate the thermally induced expansion and contraction of a tooling support structure. The expansion and contraction of the supporting structure displaces the tooling member relative to its counterpart tooling member.

Abstract:
A linear liner machine includes a base. A plurality of fluid dispensing apparatus such as, for example, sealant guns, are fixed in a stationary position in a linear configuration on the base. A conveying assembly such as, for example, a conveyor belt, conveys container closures to the sealant guns. A manipulation mechanism such as, for example, a number of motors and at least one wheel member, manipulate (e.g., rotate or spin) each of the container closures with respect to a corresponding one of the sealant guns as it dispenses a sealant to line the container closures. Accordingly, the liner comprises a plurality of independent lining stations, wherein operation of a number of said independent lining stations can be stopped while the remaining independent lining stations continue to operate to line the container closures. An associated method of lining container closures is also disclosed.
