Armed 2 tha Teeth Posted April 30, 2009 Share #1 Posted April 30, 2009 I have been wondering when the process of plastic coating ribbons began. Was Wolf-Brown the first to patent the idea? And when did they start? I am trying to find something through the US Patents office about it but does anyone know anything? Link to comment Share on other sites More sharing options...
FrankEaton01 Posted April 30, 2009 Share #2 Posted April 30, 2009 Most of the Wolf-Brown plastic ribbons are marked with the company name and either "Pat. Pend." or "Pat. No. 2392351". I did an internet search for that patent number, and a patent for "campaign bar and mounting therefor" was apparently approved in January 1946. The ribbons marked patent pending would pre-date 1946 obviously, but I don't know exactly when they were first made. Link to comment Share on other sites More sharing options...
