Mechanically Joining Metal/nonmetal And Bonding To The Metal Patents (Class 228/120)
  • Patent number: 3937384
    Abstract: A three-dimensional sign character is formed with improved circumscribing opaque metal sheet strip siding. The sign, typically having an interior light source, includes a translucent plastic face circumscribed by opaque sheet metal strip siding. The sheet metal strip siding includes a plastic strip bonded directly by gluing to a freshly abraded band on the sheet metal strip. Convolute folds are formed on either side of the sheet metal strip. One convolute fold is formed adjacent an edge of the plastic strip so as to extend angularly above and abut the plastic stripping to function as a light stop. The secured plastic strip serves as the bonding point to the translucent face of the sign.
