Definitions

  • the present invention relates to a masking member which protects a part of a surface of an article from a surface treatment such as coating, plating, vacuum evaporation, phosphatizing, and the like. More particularly, the present invention relates to a masking member produced by the molding of a sheet having a shape corresponding with a part of a surface of an article to be protected from a surface treatment wherein said masking member has (a) reinforcing rib(s).
  • said part(s) of said surface of said article may be covered and protected with said masking member.
  • adhesive tape has been used as a masking member to protect a part of a surface of an article such as a bumper of an automobile and the like. Namely, the adhesive tape is attached to said part of said surface to protect said surface from said surface treatment and after said surface treatment, said adhesive tape is removed from said surface. Said surface may not be affected by said surface treatment since said part of said surface was covered with said adhesive tape during said surface treatment.
  • adhesive tape as a masking member has faults in that attaching and removing of the adhesive tape to/from said part of said surface take time and have a high labor cost, and further, the adhesive tape attached to said part of said surface is buried in the layer of said surface treatment and it is very difficult to find the end of said buried adhesive tape to remove said adhesive tape. Said faults of adhesive tape may seriously obstruct a mass-production line such as a coating line for automobiles.
