20230091335 · 2023-03-23 · ·

A method of manufacturing a test tire and a method of setting a tread removal shape include, moving an outline of a tread surface to set a remaining groove outline, setting a point B at the intersection of a line segment extending radially from a point A, on the tread surface at a position corresponding to 70% to 80% of the tread width, and the remaining groove outline, setting the remaining groove outline farther inward than point B as a first removal reference line, setting a line passing through point B and a point L, where a straight line yielded by a tangent to the tread surface at point A being translated to point B as a second removal reference line, and removing a portion of the tread, with reference to a tread removal shape defined by the first removal reference line and the second removal reference line.

Direct address laser ablation

A system and method for selectively removing tire material from the bead portions of a cured tire to reduce one or more harmonics of at least one uniformity parameter are disclosed. According to aspects of the present disclosure, tire material is selectively removed using a plurality of direct address commands. The direct address commands specify ablation parameters for discrete ablation segments at specific angular locations around the bead of the tire. The direct address commands are generated by analyzing the desired ablation pattern for the bead of the tire. The ablation device can then be controlled to selectively remove tire material in discrete ablation segments at identified addresses pursuant to the direct address commands to achieve the desired ablation pattern on one or more tracks along the bead portion of the tire using a single pass of the ablation device.

TIRE VULCANIZATION MOLD AND MANUFACTURING METHOD FOR TIRE

A tire vulcanization mold in which a surface roughness in the groove molding portion of the tread molding surface is made smaller than a surface roughness in the land portion molding portion, in which a surface roughness in the groove molding portion is minimized to 0.12 μm or less in a range including at least a main groove molding portion, and in which a surface roughness in the land portion molding portion is made to be 3.2 μm or more, is used to manufacture a tire, and when cleaning the tread molding surface, the tread molding surface is irradiated with a laser beam to remove contaminant adhered to the tread molding surface.

Tire preparation for adhesive using laser ablation system and method

A system for preparing an interior surface of a tire for an adhesive includes a turntable configured to remove a layer of material from the tire, and a manipulator operable to move and rotate the tire. The turntable includes a platform rotatable about a first axis. An ablation module is disposed within the platform and includes one or more lasers each configured to emit a laser beam for removing the layer of material from the tire. A plurality of guide rollers extend from the platform and are operable between a retracted position and an extended position to selectively secure the tire to the platform. An exhaust system is disposed adjacent to the one or more lasers.

Counterbalanced tire profile generating machine

A tire grinding machine includes a frame having a plurality of vertically extending posts. A chuck assembly is associated with the frame and adapted to receive and rotate a tire. A grinding assembly is associated with the frame and is movable with respect to the frame. The grinding assembly has at least one grinding element adapted to contact and remove material from the tire when rotated by the chuck assembly. A counterbalance assembly which has a cable with one end connected to a counterbalance weight and an opposite end connected to the grinding assembly is included. A block assembly may be coupled to the grinding assembly to allow pivotable movement thereof. A calibration adapter may be used to ensure proper positioning of the grinding elements, wherein a level adjuster may be used for this purpose.

Internal tire balancing of rubber tires on rims
10919245 · 2021-02-16 ·

A process for balancing a rim and tire, which comprises first balancing the rim, then mounting the tire, properly inflating it and balancing a second time to determine the location and weight of balancing required. The tire and rim are then indexed with marks to indicate where the balancing weights should be placed. These indexing marks will be used at the remounting stage to assure proper balancing. The tire is then deflated and removed from the rim and the correct mass rubberized weights are vulcanized to the internal surface of the tire sidewall at the indexing mark and on the opposite sidewall across from the indexing mark. The tire is then installed back on the rim with the indexing marks lined up next to each other. The tire is re-inflated and the balance re-checked with a spin balancing machine.
