  • Patent number: 10875684
    Abstract: Methods and apparatus for sealing a threaded container are provided. More specifically, the present invention relates to a ROPP closure with a novel pilfer band that may be used to seal a bottle shaped container without pressing directly against the bottle or deforming the bottle. The bottle includes an annular ring that is novel. Optionally, the annular ring can be formed without die necking or expanding the bottle neck. At least one protrusion which extends inwardly at least partially into the bottle annular ring is formed on the ROPP closure after the ROPP closure is positioned on the bottle neck. In one embodiment, the ROPP closure includes one inwardly oriented protrusion which extends around the circumference of the ROPP closure. The protrusion can be formed by a roller. Optionally, the protrusion has a substantially uniform depth. In another embodiment, the ROPP closure includes a plurality of individuals studs which each extend at least partially into the bottle annular ring.

  • Patent number: 9718117
    Abstract: A forging method is set in a shaping hole of a die body, and the forging material is pressed with a punch to perform plastic shaping of the forging material. Ultrasonic vibration having a vibration frequency is applied to the die body with a vibration applying apparatus during the plastic shaping of the forging material. The vibration frequency is converged to a resonance frequency of the die body when the vibration frequency is within a tracking range of the vibration applying apparatus during the plastic shaping of the forging material. When the tracking range is shifted in accordance with a discontinuous change of the resonance frequency during the plastic shaping of the forging material to deviate from the vibration frequency, the reference frequency is changed so as to fall within a shifted tracking range.

    Abstract: A can bodymaker and a method of forming different sizes of drawn and wall ironed cans from the same bodymaker, in which the bodymaker includes a ram (4), a crank (22), first and second connecting rods (21, 23) and a swing lever (20) connecting the crankshaft (22) to the ram (4). Different locking positions (X, Z) are provided on the swing lever so that the first (primary) connecting rod is connected to alternative positions on the swing lever. The primary connecting rod (21) then rotates about an axis between the selected locking position and position (Y) of pivot pin 30 on the swing lever (20). The primary connecting rod drives the swing lever to rotate by a corresponding degree, and thereby converts the swing lever rotation into axial movement of the ram (4) so as to move the ram by a specific stroke length. By altering the locking pin (25) position and therefore the pivot point for the primary connecting rod, the stroke of the ram is changed.

    Abstract: Can shells are produced with tooling installed on a single action mechanical press, and the tooling includes an upper retainer supporting a blank and draw die enclosing an outer pressure sleeve and an inner pressure sleeve surrounding a die center punch, all having air actuated pistons. The die center piston has an air reservoir connected by air passages which form air springs for the inner pressure sleeve, and the outer pressure sleeve receives the same controllable air as the reservoir or low pressure plant air supply. The inner pressure sleeve has a projecting nose portion which initiates the drawing of a cup and has contoured surfaces which mate with corresponding surfaces on a die core ring to form and clamp the chuckwall of the shell during downstroke of the press. A lower panel punch forms the center panel, panel wall and countersink of the shell during upstroke of the press.

  • Patent number: 7584639
    Abstract: The aim of the invention is to produce can bodies (24?) comprising a can shell (24) and a closing element (31b, 32, 31a) that is fixed to one face of the can shell (24). Said aim is achieved by producing a tube (11) from a metal strip (1), optionally from directly adjacent sections (112), by means of a shaping step, at least one optional cutting step, and a continuous welding step, sections of said tube (11) being used as closed convex surfaces for cans. The sections are shaped by a shell-shaping device in such a way that can shells (24) are provided into which a closing element (31b, 32, 31a), especially a can bottom (31b), can be inserted. The longitudinal seam (11a, 124) can be produced inexpensively and at great precision essentially as a continuous seam in the welding step by means of simple installations.

    Abstract: To produce can bodies, a continuous can jacket is disclosed, that is sealed by way of a first joint is produced from a flat metal material. At least one sealing element is mounted on the continuous can jacket by way of an additional joint. At least one of the additional joints is configured as a laser welding seam, which forms an annular continuous sealing seam between the continuous can jacket and the sealing element(s). Before the sealing seam is welded, complementary seam contact surfaces of the can jacket and the sealing element are configured as annular continuous edge regions that flare out of narrow towards the can axis. To weld the sealing seam, the can jacket and the sealing element(s) are pushed together until the edge regions make contact, one of the end faces of the two edge regions lying on the interior of the can body and the other lying on the exterior of the body.

  • Patent number: 7073365
    Abstract: The invention relates to a method and apparatus for forming metal containers. The method involves introducing a knockout element (110) into the container body through the open end, providing a forming die shaped to reduce the diameter of the sidewall of the container body (100) when the open end of the container body (106) is forced therein to produce a neck portion of reduced diameter on the container body, driving the open end of the container body into the forming die (108), retracting the knockout element through the neck portion as the neck portion is formed, and removing the container body (106) from the forming die (108) and knockout element (110). In the invention, the driving of the open end of the container body into the forming die and/or the movements of the knockout element are carried out under computer numerical control, preferably employing linear motor drives, thereby enabling the driving or movement to be optimized for the container body and the neck portion formed thereon.
