摘要:
A method is provided for manufacturing tread for a tire without necessarily extruding the tread profile. The tread is created from multiple discrete parts that are cut from a sheet of uncured rubber material. The parts are joined together to create the tread, which can be applied to a tire immediate and cured to form a tire. Different treads formed from different rubber compositions may be created. The treads may also be created in varying shape and lengths with different rubber compositions used in different parts of the tread. One or more tread pieces can be applied to the same or different tire intermediates, which may be advantageous for simultaneous testing of different tread designs.

The present invention provides a method for extracting latex from a plant of the Asteraceae family and a method for cultivating a plant of the Asteraceae family, which allow such plants to be reused. The present invention relates to a method for extracting latex including a cutting step of cutting roots of a plant of the Asteraceae family in such a manner that the roots are partly left on the plant.

A method for precisely controlling the volume of a product such as a tire tread or tire that is placed into a mold is provided. This method includes providing a tread or tire that is built upon a portable mold core by laying a series of layers on the portable mold core. The outer diameter of the tire tread or tire is initially built to be purposely smaller than the interior surfaces of the mold in order to prevent any interference from occurring between the mold and the tire tread once the tire tread and core are placed within the mold and the mold is closed. The weight of the tire tread or tire is measured to see if the volume of the tire tread or tire is within acceptable parameters to fit within the mold. If not, additional material is added to the tire or tire tread.

Disclosed is a tire production management system, and more particularly to, a tire production management system using a radio frequency identification (RFID) tag, which may attach an RFID tag to a tire before producing a finished tire in tire manufacturing processes, recognize the tire tag attached to the tire in each of manufacturing processes, and thus manage information according to a manufacturing process on an individual tire. The tire production management system using an RFID tag comprises: an RFID tag attachment part; a plurality of RFID readers; a plurality of management terminals for respective processes; a lot management server; and a tire production management server.

A method for producing a functionalized rubber that includes adding a diene rubber selected from natural rubber, a synthetic polyisoprene rubber or combinations thereof and an organic peroxide to a mixer, the organo peroxide may be represented by the formula R1—O—O—R2, wherein R1 is selected from hydrogen or an organic moiety of between 4 and 15 carbon atoms and R2 comprises a functional moiety. The mix composition may be mixed until the mix composition reaches a target temperature of between 120° C. and 190° C. and decomposing the organic peroxide to provide a decomposition product comprising the functional moiety and reacting at least a portion of the decomposition product with at least a portion of the diene rubber to produce the functionalized rubber.

This invention relates generally to an apparatus for rotationally casting a portion of a tire, and, more specifically, to an apparatus that has a floating alignment mechanism that allows a portion of a mold to move in the radial direction of the tire, which is at least partially formed by the mold, allowing the molding apparatus to omit the use of tie bars. The mechanism may comprise two set of needle roller bearings that are orthogonally arranged to allow radial movement of a portion of a mold.
摘要:
a tire (pneumatic tire 1) provided with regularly arranged concave portions (concave portions 80) dented toward a tire inner side direction from a tire surface (tire surface 50) in at least some areas on the tire surface wherein in a direction along with the tire surface, a maximum width L of the concave portion is in a range of 0.1 micrometer or more to less than 50 micrometers, a depth D reaching to a point of the innermost part of the concave portion toward the tire inner side direction from the tire surface is within a range of 0.1 micrometer or more to less than 10 micrometers, in the direction along with the tire surface, an arrangement interval P of the concave portions is within a range more largely than 0.1 micrometer to less than 100 micrometers.
摘要:
A tire has an axis of rotation and a tread pattern that includes a plurality of tread blocks having differing circumferential shear stiffness values. The tread pattern also includes a plurality of sub-surface features that are operatively associated with at least some of the tread blocks. The combination of a tread block and a sub-surface feature can alter the circumferential shear stiffness value of tread block to thereby tune the tread pattern. A method of manufacture is also included.

A tire curing press for curing vulcanized tires includes an upper cavity part and a base that at least partially forms the lower cavity part. A movable platen is supported by the base that supports a tire mold section received within the upper cavity part. In various examples, an outer riser column is secured to the base and extends vertically upwards from the base to support the upper cavity part, a multi-height lock ring is disposed upon the base and is configured to interface with an annular flange of the upper cavity part via a bayonet connection, first and second cylinders are configured to apply a substantially equal squeeze pressure to the movable platen to thereby establish a final tire curing pressure within the press cavity, and/or a lock plate is carried by the upper cavity part and includes a locking surface for selective engagement with an abutment shoulder.
