TOP REINFORCEMENT FOR PNEUMATIC TIRES
First Claim
1. A diagonal carcass pneumatic tire the filaments of the carcass crossing each other and making an angle of from 45* to 60* with the equatorial plane of the tire, said tire comprising also a tread and a reinforcing member embeded in the tire structure between the carcass and the tread, said member consisting of a sheet of crossed series of parallel metallic elements, the angles of intersection of the elements of each series with said equatorial plane being between 45* and 60*, the same as the angularity of the carcass filaments, said elements having a high intriusic resistance to curvature in the plane of the contact surface;
- said elements being thin, the thickness thereof being only a fraction of their width, the width being in the range of several millimeters and the thicknesses of anly a fraction of a millimeter, whereby the moment of inertia in the direction of their width is very large compared with the moment of inertia in the direction of their thickness;
the elements of the two series being joined together at their points of intersection by means of a layer of rubber having a relatively low modulus of elasticity;
all whereby the reinforcing member are somewhat extensible longitudinally but resistant to transverse bending.

Abstract
Between the tread of the tire and the body of the tire, whether of the bias filament or radial filament carcass, or having no filamentary carcass, there is embedded a reinforcement band of crossed series of flat parallel elements of metal, plastic, or the like, the angles of intersection of the series being at least 45*, and the elements of each series having a high intrinsic resistance to curvature in the plane of the contact surface. The elements being of a thickness of only a fraction of their width, say a width of the order of a millimeter and a thickness of only a fraction of a millimeter. The interstices and points of intersection of the elements being filled with a rubber composition of relatively low modulus of elasticity. Alternatively, instead of being of metal, plastic, glass fibre, or the like, the bands may be composed of impregnated stranded elements embedded in a rubber having a high modulus of elasticity.
