Abstract
A cord-embedded rubber tape, a tire component made by winding such a tape, and a pneumatic tire comprising such a tire component are disclosed, wherein the tape is made of unvulcanized rubber and at least one cord is embedded therein along the length of the tape. The unvulcanized rubber may include short fibers oriented in the longitudinal direction of the tape.
Claims11
A tape to be wound into a tire component which is made of unvulcanized rubber in which a single cord is embedded along the length thereof,
- the cord having a diameter being in a range of from 0.3 to 1.5 mm, wherein
- on each side of the cord embedded portion, a reduced thickness portion having a substantially constant thickness is formed, and the thickness of the tape in the cord embedded portion is larger than the thickness of the tape in each said reduced thickness portion so that the cord is completely embedded in the unvulcanized rubber, and
- each said reduced thickness portion is wider than the cord embedded portion.
A tape to be wound into a tire component which is made of unvulcanized rubber in which a single organic fiber cord is embedded along the length thereof, wherein
- on each side of the cord embedded portion, a reduced thickness portion having a substantially constant thickness is formed, and the thickness of the tape in the cord embedded portion is larger than the thickness of the tape in each said reduced thickness portion so that said organic fiber cord is completely embedded in the unvulcanized rubber, and each said reduced thickness portion is wider than the cord embedded portion.
A tape to be wound into a tire component which is made of unvulcanized rubber in which a single cord having a diameter in a range of 0.3 to 1.5 mm is embedded along the length thereof, wherein
- on each side of the cord embedded portion, a reduced thickness portion having a substantially constant thickness is formed, and the thickness of the tape in the cord embedded portion is larger than the thickness of the tape in each said reduced thickness portion so that said cord is completely embedded in the unvulcanized rubber, and each said reduced thickness portion is wider than the cord embedded portion, and the total width of the tape is in a range of from 10 to 30 mm.
A tire component made of windings of a tape, wherein
- said tape is made of unvulcanized rubber in which a single cord is embedded along the length thereof,
- on each side of the cord embedded portion, a reduced thickness portion having a substantially constant thickness is formed, and the thickness of the tape in the cord embedded portion is larger than the thickness of the tape in each said reduced thickness portion so that the cord is completely embedded in the unvulcanized rubber, and
- each said reduced thickness portion is wider than the cord embedded portion.
A pneumatic tire comprising a tire component made of windings of a tape, wherein
- said tape is made of unvulcanized rubber in which a single cord is embedded along the length thereof,
- on each side of the cord embedded portion, a reduced thickness portion having a substantially constant thickness is formed, and the thickness of the tape in the cord embedded portion is larger than the thickness of the tape in each said reduced thickness portion so that the cord is completely embedded in the unvulcanized rubber, and
- each said reduced thickness portion is wider than the cord embedded portion.
