  • Apparatus for treating edge-bead formation
    Patent number: 4117798
    Abstract: In the flow coating of inverted metal cans, an unhardened bead of excess coating material at the lower edge of the can is removed in a thinner bath through which the can is passed while hanging suspended from a conveyor. The thinner dissolves the bead and removes the coating on the lower edge of the can. The conveyor lifts the can out of the pool on a gradually rising path with the can hanging essentially vertical. Unhardened coating on the can sidewall above the area from which it has been removed, flows down and recoats the lower edge essentially uniformly but not to excessive thickness.
    Type: Grant
    Filed: January 10, 1977
    Date of Patent: October 3, 1978
    Assignee: Eagle-Picher Industries, Inc.
    Inventors: James W. Cornelius, Robert T. Mallon
