  • Patent number: 7185525
    Abstract: A method is provided for forming an end closure for a surrounding sidewall of a container, such as an aluminum can. The method includes forming a central body panel oriented transversely to the central axis of the can and forming an outer surrounding margin portion joined to the sidewall such that the margin portion has a support section oriented longitudinally relative to the sidewall. A portion of the margin is corrugated to provide a rib structure having longitudinally extending first rib components located on the support section. This method can be accomplished during the ironing and doming of a can.

  • Patent number: 6736284
    Abstract: An end closure for a container, such as a beverage or food can, includes a transverse central body panel and a surrounding outer margin joined to the longitudinal side wall of the container body. The margin portion has a support section, and a plurality of spaced rib structures are located on the margin and have portions that extend longitudinally along the support section to reinforce the margin. The end closure can be a lid or an integrally formed bottom for a can body. The margin can have a U-shaped profile with the rib structures located on either the inner or outer wall portion thereof. The rib structures may be flutes defining tear-dropped shaped depressions. The invention contemplates a can body with the end closure forming the bottom thereof. A method is described for forming such end closures and containers.

  • Patent number: 6361602
    Abstract: A coating station for an apparatus and method used to coat at least one side of a pontinuous strip of material includes a housing having a conduit that connects to a source of coating material, a fluid dispensing passageway and a wick that contacts the strip. The passageway has an intake port and a discharge port. A metering member is interposed in the passageway, and a drive rotates it about an axis between the intake and discharge ports. The metering member has a metering bore, and a reciprocating metering piston is disposed in the bore. The metering member may be a cylindrical shaft, and one or more metering bores extend diametrically through the shaft with each being provided with a piston to dispense predetermined amounts of coating material onto the strip.

  • Patent number: 5768932
    Abstract: A forming apparatus uses counteracting, hydraulically coupled pistons to form a dome structure in the bottom panel of the container, such as a beverage can. A pressure ring is on one piston, and a doming die is on the other piston. The pistons are received in a piston housing that also provides a primary fluid reservoir so that, when one piston moves in one direction to displace fluid, the displaced fluid moves the other piston in the opposite direction. The pistons are coaxial and one is received in the other. Return springs are provided to bias the pistons into a desired orientation. A secondary reservoir may be provided to receive overflow fluid. Here, a first one-way valve sets a threshold so that fluid will flow into the secondary reservoir when the pressure in the primary reservoir exceeds the threshold. A second one-way valve permits fluid to return to the primary reservoir when the return springs move the pistons to a starting orientation.

  • Patent number: 5682786
    Abstract: A forming apparatus for doming containers employs a pair of pistons, a pressure ring and doming die. One piston carries the pressure ring, and the other piston carries the doming die. The pistons are mechanically linked so that they move in a counteracting manner thus reducing the stroke distance necessary to dome the container. This further reduces the impact energy on the container. The mechanical linkage is preferably pairs of rack and pinion gears moving the pistons in opposite directions of travel.

  • Patent number: 5549752
    Abstract: Apparatus for applying a coating material, such as a lubricant, to the top and bottom surfaces of a continuous strip of material wherein the continuous strip of material is passed between two wicks mounted in each of an upper and lower housings with each of the housings having a plurality of spaced apart bores and wherein metered amounts of the coating material is supplied sequentially to each of the plurality of spaced apart bores by a piston mounted for reciprocating movement. In another embodiment, the wicks apply coating material to the outer surface of an upper drive roll and a lower idler roll so that coating material is applied to the upper and lower surfaces of a continuous strip of material as it passes therebetween.

  • Patent number: 5357779
    Abstract: A can body maker apparatus including a stationary support frame; a housing having forming and ironing dies located therein mounted on the support frame; an elongated ram; a reciprocating ram drive; and a redraw assembly which includes a redraw sleeve for supporting a can body preform thereon; a redraw carriage for supporting and axially displacing the redraw sleeve relative the ram; a redraw electromagnetic coil fixedly positioned relative the stationary support frame; and a permanent magnet fixedly mounted with respect to the redraw carriage in displace relationship with the coil along the coil axis for co-acting with the electromagnetic field produced by the coil for controllably reciprocatingly displacing the redraw carriage.

  • Patent number: 5353619
    Abstract: An apparatus and method for necking tubular members such as cans utilizes an inner die that expands to support a neck portion to be formed by an outer die that travels around the neck. The inner die has a plurality of first die elements which may be retracted after the neck is formed so that the inner die may be removed. Selected ones of these first die elements nest with the others in the retracted state. Drive assemblies operate each of the inner and outer dies, and the drive assembly for the inner die operates to differentially drive the first die elements to allow nesting to occur. Preferably, the inner drive assembly employs a reciprocally retracting cam, and the first die elements have cam followers to allow reciprocation. A wedge cam can be used to support the first die element sin the expanded configuration, and a wedge drive moves the wedge cam into and out of position.
