TTie New Discoveries in Rubber Manufacture 
J^ow applied to U.S.Koyal Cords 
B y this time you have probably read 
the newspaper announcements of the 
three greatest discoveries in tire manufac¬ 
ture in the history of tires. 
For your convenience we repeat them— 
1. Sprayed Rubber— the first truly pure rubber. 
2. Web Cord—a rubber-webbed sheet of cords 
with every filament of each cord impreg¬ 
nated and surrounded by pure natural 
rubber. It does away with all cross 
tie-threads. It is the most substantial 
step in friction elimination since the 
old type square woven fabric gave 
way to cord construction. 
3. The new Flat Band Process of building a cord 
tire — ensuring for the first time a uniform 
tire equalized through and through in resili¬ 
ency and resistance to puncture and wear. 
These three new major contributions to 
the art of rubber manufacture have been 
utilized to give the Royal Cord a better, 
longer lived—more resilient carcass and a 
better, stronger, longer wearing tread. 
Again you see U. S. Royal Cords living 
up to their leadership obligations. 
Again you see U. S. Royal Cords prac¬ 
ticing what they preach: 
Competition for greater public confi¬ 
dence and larger public service.
