Abstract
An ornamental ring-shaped metal gem formed of a wire maze, and produced by a process including forming, on a mandrel, a wire weave having a length exceeding a thickness of the manufactured gem, thereafter inserting the mandrel, together with the wire weave into a tubular element of a die, which also includes a cylindrical bottom portion supporting the tubular element and defines a stop surface for the mandrel, and applying pressure to the wire weave to form the gem.
Claims4
A method of manufacturing an ornamental ring-shaped metal gem formed of a wire maze, said method comprising the steps of:
- providing die means including a cylindrical bottom portion, an outer tubular element supported on said bottom portion, and a mandrel insertable into said tubular element and supported on said bottom portion against a stop surface, said mandrel having an outer diameter smaller than an inner diameter of said tubular element by an amount corresponding to a width of the wire maze of which the ring-shaped metal gem is formed;
- forming, on said mandrel, a wire weave having a length exceeding a thickness of the manufactured ring-shaped metal gem;
- thereafter, inserting said mandrel, together with the wire weave, into said tubular element;
- and
- applying pressure to the wire weave to form the ring-shaped metal gem.
