COMPOSITE WIRE REINFORCEMENT FOR A TIRE, COATED WITH RUBBER HAVING ENHANCED WATER-BARRIER PROPERTIES
Publication number: 20130146198Abstract: A composite wire or thread-based reinforcement is coated with rubber and may be used for reinforcing a finished rubber article, such as a tyre. The reinforcement includes one or more textile or metallic reinforcing wires or threads, and a coating rubber that coats each wire or thread.
