Abstract
Cylindrical embossing tools are constructed from one or more masters formed by accurately scribing the face of a substrate along three axes in the face to produce a pattern of tetrahedrons. The plurality of masters, or replicated copies made from a single master, are assembled in a fixture and seamless copies are made by electrodeposition of nickel using various shielding and grinding methods to provide replicated copies of uniform thickness. The replicated copies are assembled and used to form larger electroforms until a generally cylindrical embossing tool of the correct width and circumference is created. Novel processes and apparatus are provided for removing the electroformed cylindrical tool from its mother cylinder.
