  • Method for statically forming rolled lampshade edges
    Patent number: 5496511
    Abstract: Lampshades are formed by fitting a lampshade blank on a mandrel of complementary shape, which mandrel also supports upper and lower metal hoops to be incorporated into the lampshade. The edges of the lampshade blank are then locally heated and deformed to surround the metal hoops. The deformation of the heated edges of the lampshade blank may advantageously be effected by surrounding the lampshade/mandrel assembly with a membrane, and forcing the membrane into contact with the assembly.
