摘要： It now has been found that uncured modified rubber compositions comprising mixtures of elastomers and a reinforcing filler can be prepared having improved properties. More particularly, such uncured modified rubber compositions can be prepared by a process which comprises the steps of(A) preparing a first mixture comprising an elastomer, at least one reinforcing filler and at least one chemical agent capable of promoting the formation of filler-elastomer linkages;(B) preparing a second mixture comprising(i) an elastomer, at least one reinforcing filler and at least one chemical agent capable of promoting the formation of filler-elastomer linkages, wherein at least one of the elastomer, filler or chemical agent in the second mixture is different from the elastomer, filler or chemical agent in the first mixture; or(ii) an elastomer and at least one reinforcing filler; or(iii) at least one reinforcing filler and at least one chemical agent capable of promoting the formation of filler-elastomer linkages; or(iv) an elastomer and at least one chemical agent capable of promoting the formation of filler-elastomer linkages; and(C) blending the first and second mixtures to form a third mixture. Examples of such useful chemical agents include aromatic furazan oxides, heterocyclic di-N-oxides, 1-hydroxy-benzimidazole-3-oxide compounds, 1,3-dihydroxy-benzimidazolinone compounds, and aromatic nitroso compounds.The invention also includes filled vulcanizates prepared by vulcanizing the uncured modified rubber compositions prepared in accordance with the above method. Rubber articles and portions thereof made from such vulcanizates such as tires, hoses, belts, treads, sidewalls and the like are also within the scope of the present invention as well as methods of reducing the rolling resistance of tires.

摘要： A method and apparatus for forming contoured tire carcass strips having a body ply consisting of two strips of elastomeric material containing individually spaced reinforcing cords sandwiched therebetween, an innerliner, a pair of abrasive gum sections, and pairs of first and second sidewall sections. The carcass strip and reinforcing cords have a contour configuration with a wider central portion and a pair of outwardly flared end portions connected to the central portion by two intermediate portions. The transverse distances between the cords are equal, with the distances being greater at the central portion than the intermediate and end portions. A grooved forming plate has a plurality of grooves in one surface in the configured pattern that the cords will take when sandwiched in the body ply. The cords are placed in the grooves of the forming plate and have two strips of elastomeric material applied thereto by a pair of vacuum transfer plates and a press. The first sidewall sections and abrasive gum sections are applied to one surface of the body ply by another vacuum transfer plate to form a composite strip. The second sidewall sections are then applied to an opposite side of the body ply by another vacuum transfer plate to form the tire carcass strip. A plurality of the tire carcass strips then are applied in juxtaposition on a toroidal mandrel and assembled with a pair of tire bead assemblies to form a green tire carcass for subsequent placement in a tire-forming mold.
