DEFINITION

Classification: 152/451

Tire cord reinforcement materials, per se:

(under subclass 450) Subject matter wherein significance is attributed to the strengthening material or its structure and not the location of its application or use in the tire casing.

(1) Note. The cord materials in this subclass are materials for tire reinforcement which are not claimed as specific components of the belt, breaker, bead or carcass portions of a tire. Because of the nature of these materials, this subclass is exclusive in nature rather than inclusive in order to collect materials used in tire casings which are of a general nature and not specifically claimed for use in particular portions of the tire casing.
