Abstract:
1. A method to produce a fabric applique, comprising the steps of: (a) providing a piece of high carbon non-stainless steel including (b) removing oxide layers from said exterior surfaces; (c) forming a detailed pattern on said steel, said pattern comprising (d) etching through said intermediate cover portions and etching said steel beneath said intermediate cover portions to produce (e) promptly after said etching is completed removing said photo resist cover portions from said safety die; (f) promptly after said photo resist cover portions are removed applying to said safety die a protective non-stick coating having a thickness in the range of 0.0008 to 0.0012 inch to round edges on said die and minimize corrosion of said safety die, said non-stick coating not sticking to fabric; (g) providing a pair of spaced apart parallel rollers; (h) providing a stack of a plurality of fabric sections to be cut by said safety die, each fabric section having a thickness of less than 0.010 inch; (i) providing a thin metal plate having a thickness of at least 0.010 inch; (j) providing a pair of polymer bounding sheets; (k) forming a die cutting laminate package by sandwiching said die, said stack of fabric sections, and said metal plate between said polymer sheets with said (l) feeding said die cutting laminate package intermediate said rollers such that said rollers compress said laminate package and cause said rounded cutting edge portions to compress and cut through said stack of fabric sections to produce a plurality of detailed fabric pieces of equal shape and dimension; and, (m) attaching each of said detailed fabric pieces to a substrate.
