Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
111 words
A breaker band for tires comprising: a plurality of plies of biased rubberized tire cord fabric arranged to form an endless band having substantially parallel edges, the cords of a ply arranged at a desired angle from the equatorial plane of the band, and the band concurrently bevel cut circumferentially at desired facing angles at the edges to define a breaker band of substantially uniform trapezoidal cross-section with the cords bevel cut in equatorial and radial planes of the band where the radially inner band width is greater than the radially outer band width, and the bevel cuts of the cords form facing angles with the equatorial plane of the band.
Claim 2
Dependent Claim
111 words
A breaker band for tires comprising: a plurality of plies of biased rubberized tire cord fabric arranged to form an endless band having substantially parallel edges, the cords of a ply arranged at a desired angle from the equatorial plane of the band, and the band concurrently bevel cut circumferentially at desired facing angles at the edges to define a breaker band of substantially uniform trapezoidal cross-section with the cords bevel cut in equatorial and radial planes of the band where the radially inner band width is greater than the radially outer band width, and the bevel cuts of the cords form facing angles with the equatorial plane of the band.
Claim 3
Dependent Claim
22 words
A breaker band as set forth in claim 1 wherein the cords are bevel cut at angle from 22* to 50* .
Claim 4
Dependent Claim
135 words
In a tire having casing cords and a continuous peripheral tread, the improvement which comprises providing between the casing cords and tread a breaker band reinforcement which includes: a plurality of plies of biased rubberized tire cord fabric arranged to form an endless band having substantially parallel edges, the cords of a ply arranged at a desired angle from the equatorial plane of the band, and the band concurrently bevel cut circumferentially at desired facing angles at the edges to define a breaker band of substantially uniform trapezoidal cross-section with the cords bevel cut in relation to equatorial and radial planes of the band where the radially inner band width is greater than the radially outer band width and the bevel cuts of the cords form facing angles with the equatorial plane of the band.
Claim 5
Dependent Claim
135 words
In a tire having casing cords and a continuous peripheral tread, the improvement which comprises providing between the casing cords and tread a breaker band reinforcement which includes: a plurality of plies of biased rubberized tire cord fabric arranged to form an endless band having substantially parallel edges, the cords of a ply arranged at a desired angle from the equatorial plane of the band, and the band concurrently bevel cut circumferentially at desired facing angles at the edges to define a breaker band of substantially uniform trapezoidal cross-section with the cords bevel cut in relation to equatorial and radial planes of the band where the radially inner band width is greater than the radially outer band width and the bevel cuts of the cords form facing angles with the equatorial plane of the band.
Claim 6
Dependent Claim
25 words
A tire as set forth in claim 3 wherein the cords of the breaker band are beveled cut and at angles from 22* to 50*.
