  • Patent number: 6305210
    Abstract: Method and apparatus are disclosed for fabricating a one-piece can body, with profiled closed end, from flat rolled steel of selected thickness gauge and tensile strength. Such steel substrate is electrolytically metal plated to facilitate sidewall ironing into an elongated sidewall can body for pressurized beverage packs. An axially-recessed bead is formed in the endwall of a drawn cup by pulling sidewall metal for movement into such endwall. That preformed bead being symmetrically positioned in the drawn cup such that a bodymaker redraw of the drawn cup positions sheet metal of the preformed bead so as to constitute a closed end angled portion, which extends from a circular configuration base support toward contiguous sidewall.

  • Patent number: 5599395
    Abstract: In-line flat-rolled steel cleansing and finishing apparatus is disclosed which enable flat-rolled steel, as supplied with surface areas contaminated with iron fines and other debris from gauge reduction operations, to be continuously processed in-line, free of interruptions for cleansing purposes. Continuous-strip apparatus is disclosed which enable in-line continuous-strip cleansing in a manner which decreases iron fines carried by strip surfaces to a desired level while providing for continuous uniform cleansing. Carry-over of iron fines from the cleansing operations so decreases such that iron content of a coating means is decreased resulting in improved corrosion-protection coating. Diminishing iron content in a hot-dip galvanizing bath increases efficiency of aluminum additions and diminishes iron-aluminum dross.

  • Patent number: 5590558
    Abstract: Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary can packs free of any requirement for applying organic coating or adding organic coating for repair purposes after fabrication and before such direct usage. Cupping of precoated flat-rolled sheet metal can stock using preselected tooling configurations and clearance avoids any increase in side wall metal thickness gage. Tension elongation during redraw is controlled over side wall height by clamping solely between planar clamping surfaces, tooling configurations and preselected clearances to decrease thickness gage uniformly over side wall height between flange metal open end of can body and curved transition zone at closed end. Surface area of the cavity entrance zone for each die is fabricated about multiple radii forming sharp edge about which coated can stock is drawn into each die cavity.

  • Patent number: 5590755
    Abstract: Method of manufacturing, assembling and fabricating a woven-wire belt with unitary vertically-oriented lateral edge flattened-wire helically-wound surfaces along each lateral edge for dynamic-frictional drive of the belt by a rotatable substantially-cylindrical drive surface in a helically-curved path, free of any mechanical drive connection while in the helical path. Lengthwise-directed tension control of the belt is exercised, while the belt is exterior to the helically-curved path, to achieve desired frictional drive contact within the drive surface. An exterior travel path for the belt between exit from and return to the helically-curved path provides an endless belt travel array.

  • Patent number: 5590993
    Abstract: Scoreline, profiling and reinforcing features are provided for an easy-access sheet metal end closure (20) and an integral opener (44). An endwall panel (28) is formed so as to substantially eliminate flexing of the sheet metal during rupture of residual metal of scoreline means defining a U-shaped tear strip (30). Such tear strip is oriented with its arcuately-shaped closed end (32) contiguous to the periphery of such endwall panel with scoreline legs (34,35) directed toward a portion at its geometric center (26). The opener is fabricated with a chisel-point (92) at its working end (66) to initiate puncture of such arcuate-shaped scoreline by Class I lever action. Rupturing of the scoreline is followed by pivoting of the opener about a pair of fulcrum points (82,83) which contact the panel one each external to a side of opening 62, with movement of the opening about such fulcrum points rupturing the scoreline legs by Class II lever action.

  • Patent number: 4981084
    Abstract: A computer assisted transit car door operating system for augmented automation of transit car door panel operation while providing safety provisions to restrain rail movement unless all passage doorways are closed. A programmable logic controller generates a sequence initiating (opening or closing) signal for a door panel; or, a manual input signal can be introduced for such purpose. The controller receives signals from a panel position sensor and a panel movement sensor to evaluate door panel status and generate status indication and panel movement signals. Automated control of door panel movement is selectively directed to a doorway, or doorways, at which an opening or closing problem is being encountered; that is, the exclusion of door panel movement signals to properly operated door panels.
