DEFINITION

Classification: 152/526

Characterized by belt or breaker structure:

(under subclass 450) Subject matter which includes one or more relatively thin threads, filaments, yarns, wires, cables, bands, braids or the like formed into cords or reinforcing elements which are arranged parallel to each other to form a ply which annularly extends continuously around the tire casing substantially from shoulder region to shoulder region of a tire tread to add strength to said tire tread area or to protect the tire casing in this region.

(1) Note. The threads, filaments, yarns, etc., may be of wire, glass, natural or synthetic fibers usually referred to in the art as cords. Cords arranged in a substantially parallel relationship constitute a ply.

(2) Note. The annular arrangement of reinforcing material in a ply between the tread and carcass is commonly referred to as a belt or breaker. Traditionally belts have been employed for reinforcement and hoopstrength whereas breakers have been employed for the protection of underlying carcass layers. However, the terms are sometimes used interchangeably in the art.
