Abstract
Abstract A pneumatic tire and a breaker assembly therefor, the breaker assembly being interpositioned between the carcass of the tire and a tread overlying the crown region of the carcass, is disclosed. The breaker assembly includes a pair of plies one of which plies is folded to present three continuous ply layers. Two of the ply layers, via confronting fold regions, are divided to define an annular gap in the breaker assembly which is bridged by the other of the plies.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
145 words
A pneumatic tire comprising a carcass having a circumferential crown region, a tread overlying said crown region, and a breaker assembly interposed between said tread and carcass, said breaker assembly comprising a pair of plies at least one of which is folded, said folded ply including two pairs of opposing fold regions, each pair of said fold regions including an axially outer fold and an axially inner fold, each said axially inner fold being spaced proximate to the other said axially inner fold to define an annular gap therebetween, the other of said plies being superposed upon said folded ply and having an axial extent sufficient to bridge said annular gap, said folded ply terminating in a pair of axially opposite marginal edges each of which is concealed between the axially inner fold and the axially outer fold of its corresponding pair of fold regions.
Claim 2
Dependent Claim
145 words
A pneumatic tire comprising a carcass having a circumferential crown region, a tread overlying said crown region, and a breaker assembly interposed between said tread and carcass, said breaker assembly comprising a pair of plies at least one of which is folded, said folded ply including two pairs of opposing fold regions, each pair of said fold regions including an axially outer fold and an axially inner fold, each said axially inner fold being spaced proximate to the other said axially inner fold to define an annular gap therebetween, the other of said plies being superposed upon said folded ply and having an axial extent sufficient to bridge said annular gap, said folded ply terminating in a pair of axially opposite marginal edges each of which is concealed between the axially inner fold and the axially outer fold of its corresponding pair of fold regions.
Claim 3
Dependent Claim
52 words
A pneumatic tire as claimed in claim 1, wherein each of said pairs of opposing fold regions in cross-section defines three circumferential ply layers axially continuous with one another, one of said ply layers being interposed between the other two ply layers and terminating in a corresponding one of said marginal edges.
Claim 4
Dependent Claim
39 words
A pneumatic tire as claimed in claim 2, wherein said annular gap has an axial extent which is less than the axial extent of said one of said ply layers which is interposed between the other two ply layers.
Claim 5
Dependent Claim
39 words
A pneumatic tire as claimed in claim 2, wherein said annular gap has an axial extent which is greater than the axial extent of said one of said ply layers which is interposed between the other two ply layers.
Claim 6
Dependent Claim
25 words
A pneumatic tire as claimed in claim 2, wherein said annular gap is symmetrically disposed relative to a median equatorial plane of said breaker assembly.
Claim 7
Dependent Claim
25 words
A pneumatic tire as claimed in claim 2, wherein said annular gap is asymmetrically disposed relative to a median equatorial plane of said breaker assembly.
Claim 8
Dependent Claim
23 words
A pneumatic tire as claimed in claim 2, wherein said other of said plies directly confronts said annular gap of said folded ply.
Claim 9
Dependent Claim
18 words
A pneumatic tire as claimed in claim 7, wherein said other of said plies surrounds said folded ply.
Claim 10
Dependent Claim
18 words
A pneumatic tire as claimed in claim 7, wherein said folded ply surrounds said other of said plies.
Claim 11
Dependent Claim
39 words
A pneumatic tire as claimed in claim 7, wherein said other of said plies directly confronts said one of said ply layers of said folded ply which is interposed between the other two ply layers of said folded ply.
Claim 12
Dependent Claim
86 words
A pneumatic tire as claimed in claim 10, wherein said other of said plies is also folded and presents a pair of axially opposite fold regions each of which is proximate to a corresponding one of said axially outer folds of the first said folded ply, the second said folded ply circumferentially embracing via at least one of its fold regions said one ply layer of the first said folded ply which is interposed between the other two ply layers of the first said folded ply.
Claim 13
Dependent Claim
65 words
A pneumatic tire as claimed in claim 7, wherein a second one of said ply layers which interconnects the first said one of said ply layers with the remaining ply layer is bent such that only a portion thereof lies in the same circumferential plane as the first said one of said ply layers and is spaced from said corresponding one of said marginal edges.
Claim 14
Dependent Claim
38 words
A pneumatic tire as claimed in claim 2, wherein said other of said plies is separated from said annular gap by one of the other two ply layers between which is interposed said one of said ply layers.
