With Electromagnetic And/or Electrostatic Removal Of Excessive Deposit, E.g., Detearing Patents (Class 118/639)
  • Patent number: 9689063
    Abstract: There are provided an electromagnetic wiping device, a plated steel sheet wiping apparatus including the electromagnetic wiping device, and a method for manufacturing a plated steel sheet. A portion of a plating layer of a steel sheet having passed through a plating bath is preliminarily removed at least in an edge region of the steel sheet, and a gas wiping operation is performed. Therefore, overplating is prevented at least in the edge region of the steel sheet. In addition, since the load of gas wiping can be reduced while maintaining the line speed of the steel sheet, the quantity of scattered particles and the formation of dross can be reduced for improving the plating quality of the steel sheet and the productivity of a manufacturing process.

In yet another approach, the color of a coating that is applied to an object is shifted to match a background color so that the coating appears to be erased. In this approach, the coating may be in the form of a label, such as a bar code, that can be read by a scanner at a point of sale location.
