Abstract

A pneumatic tire includes an integrated belt/overlay component having a plurality of individually dipped and tackified cords applied individually to the tire component.

First claim

What is claimed is:

1 . A pneumatic tire comprising an integrated belt/overlay component having a plurality of individually dipped and individually tackified cords applied individually to the tire.

2 . The pneumatic tire as set forth in claim 1 wherein the component is a tread reinforcement structure at least partially including a plurality of individually dipped and tackified cords oriented from −7° to +7° relative to a circumferential direction of the pneumatic tire.

3 . The pneumatic tire as set forth in claim 1 wherein the cords are constructed of two or three twisted aramid yarns.

4 . The pneumatic tire as set forth in claim 1 wherein a finish is applied to dipped cords during or after a dipping process, the finish providing tack to the component.

5 . The pneumatic tire as set forth in claim 1 wherein the component is disposed radially between a tread and a carcass ply.

6 . The pneumatic tire as set forth in claim 1 wherein the cords are applied directly on to another tire component during a building process of an uncured pneumatic tire.

7 . The pneumatic tire as set forth in claim 6 wherein the tire component is a carcass ply.

8 . The pneumatic tire as set forth in claim 1 wherein the cords are constructed of one of the following materials: aramid, PEN, PET, PVA, PBO, POK, rayon, nylon, carbon, and glass fiber.

9 . A method for constructing an integrated belt/overlay component of a pneumatic tire, said method comprising the steps of:
pretreating an individual cord by dipping the individual cord in a first solution or emulsion; drying the dipped individual cord; tackifying a surface of the dipped and dried individual cord with a second solution or emulsion; and applying the tackified individual cord on a surface of an uncured tire component.

10 . The method as set forth in claim 9 wherein the tackified individual cord is applied to the uncured tire component on a tire building drum.

11 . The method as set forth in claim 9 wherein the second solution or emulsion comprises a rubber compound dissolved in a solvent.

12 . The method of claim 11 wherein the solvent comprises a petroleum derivative.

13 . The method as set forth in claim 9 wherein said applying step occurs without calendering of the individual cord.

14 . The method as set forth in claim 9 wherein the dipping includes dipping the individual cord in the first solution or emulsion and dipping the dipped individual cord in a further solution or emulsion.

15 . The method of claim 14 wherein the further solution or emulsion is an aqueous emulsion comprising a rubber latex containing resorcinol formaldehyde (RFL) resin.
