New or improved tires and retreads for tires which incorporate Trinidad Lake Asphalt (TLA), also known as Trinidad Natural Asphalt or Epure, as a raw material therein. TLA is advantageously used in addition to or as a substitute for other known component(s) or raw material(s) in tire/retread formula ...
A tire having a ground contacting tread comprising tread grooves which divide the tread into a plurality of tread pattern elements provided on its radially outer surface with a radially outwardly projecting ridge disposed on an edge of the pattern element and at least one radially inwardly projectin ...
A low noise tire tread includes a base pitch sequence 1, 1, 2, 3, 3 extending in the circumferential direction C about at least a portion of the tire. A bias pitch sequence 1A.... 1G, 2A... .2G or 3A.... 3E is embedded within at least one of the base pitches and desirably in a majority of, or prefer ...
Method and apparatus for post-cure correction (PCC), either partial or substantial, of various tire nonuniformities which have been detected during a tire manufacturing process by a tire uniformity machine (TUM), preferably testing a tire (120) which has been nominally cooled down (i.e., nominally c ...
An automated tire manufacturing curing module (10) according to the present invention is illustrated. This system or module (10) provides for the complete vulcanization of pneumatic tires at one tire curing module (10) using only one mold (50) for a particular tire size or style. This curing module ...
A method for making a preassembly of a sealant (17, 100) useful in tire manufacturing. The method of making the preassembled sealant includes extruding a center strip (15) and at least two axially outer strips (10, 20) of a sealant onto a first conveyor belt (30); wherein the center strip and the ax ...
PROBLEM TO BE SOLVED: To provide a halved mold for tire molding which can manufacture a high-performance tire, eradicate faults during vulcanization molding by preventing a tire from being nipped in during mold clamping and increase yield, and a tire manufacturing method.SOLUTION: A sliding unit mec ...
(EN) A method of manufacturing a tire having first color characters or lines on at least one side wall part, comprising the steps of stamping a second color side wall rubber and a first color side wall rubber on the side face of a carcass member formed in a toroidal shape by winding, a plurality of ...
(EN) This aims to improve the uniformity of a pneumatic tire. Disclosed is a pneumatic tire manufacturing method comprising a strip winding step (S3) of winding rubber strips (20) circumferentially and spirally over such a ply inside portion (6A1a) of a cylindrical ply (6A1) wound on a shaping forme ...
PROBLEM TO BE SOLVED: To provide a tire manufacturing method capable of always effectively developing an electroconductive function without relying on the pattern or the like of a tire, and the tire manufactured thereby.SOLUTION: In a case that the tire 1 is molded by winding a rubber strip material ...
