Abstract

Abstract A pneumatic tyre has a crown- reinforcing belt (6) comprising two superposed cord fabric plies (7, 8), the reinforcing cords (9) thereof being formed from a non- or substantially non-heat shrinkable material, e.g. steel wire, whilst the reinforcing cords (10) thereof are formed from a heat shrinkable plastics material, e.g. a polyester or polyamide. During vulcanization of the tyre, the reinforcing cords (10) shrink in length and thereby provide edge regions R of the belt which have a reduced cord density and thus greater pliability. <IMAGE>

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 70 words
A pneumatic vehicle tyre having a belt comprised of filamentary reinforcing members arranged in cord ply, which belt at its edges has a reduced filament density, in which the reinforcing members comprise members formed from non- or substantially non-heat shrinkable material and members formed from heat-shrinkable plastics material, the reinforcing members formed of heat-shrinkable plastics material being located between the reinforcing members formed of non- or substantially nonheat shrinkable material.
Claim 2
Dependent Claim 70 words
A pneumatic vehicle tyre having a belt comprised of filamentary reinforcing members arranged in cord ply, which belt at its edges has a reduced filament density, in which the reinforcing members comprise members formed from non- or substantially non-heat shrinkable material and members formed from heat-shrinkable plastics material, the reinforcing members formed of heat-shrinkable plastics material being located between the reinforcing members formed of non- or substantially nonheat shrinkable material.
Claim 3
Dependent Claim 42 words
A pneumatic vehicle tyre as claimed in claim 1, in which, seen in the circumferential direction of the tyre, a reinforcing member formed of non- or substantially non-heat shrinkable material is followed by a reinforcing member formed of a heatshrinkable plastics material.
Claim 4
Dependent Claim 44 words
A pneumatic vehicle tyre as claimed in claim 1, in which, two or more reinforcing members formed of heat-shrinkable plastics material are arranged between two successive reinforced members formed of non- or substantially non-heat shrinkable material, seen in the circumferential direction of the tyre.
Claim 5
Dependent Claim 28 words
A pneumatic vehicle tyre as claimed in claim 3, in which the reinforcing members of heat-shrinkable plastics material are each comprised of plastics material of varying heat shrinkage.
Claim 6
Dependent Claim 27 words
A pneumtic vehicle tyre as claimed in any preceding claims in which the non- or substantially non-heat shrinkable reinforcing members are formed of steel wires or cords.
Claim 7
Dependent Claim 24 words
A pneumatic vehicle tyre as claimed in any preceding claim in which the heat-shrinkable reinforcing members are formed of a polyamide or a polyester.
Claim 8
Dependent Claim 18 words
A pneumatic vehicle tyre, substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
Claim 9
Dependent Claim 18 words
A pneumatic vehicle tyre, substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
