  • Patent number: 7132930
    Abstract: The invention provides a monitoring device and tire combination wherein an antenna is mounted to the tire in a location spaced from the monitoring device. In one embodiment, the antenna may be mounted to the tire sidewall outside the body cords of the tire. The antenna may be mounted on the outer surface of the sidewall or embedded within the body of the sidewall. The antenna is connected to the monitoring device with a connector. The connector may be electrically coupled to the monitoring device or may be connected to the monitoring device with a plug and socket connection. When the antenna is outside the body cord, the connector may extend from the antenna through the bead filler, over the top of the turn up, or under the bead ring.

  • Patent number: 7122220
    Abstract: A method of creating an air barrier on both sides of an innerliner splice on the inside surface of a green tire when a bladder release lubricant is being applied thereto to prevent contamination of the splice. High pressure air is directed through air nozzles on both sides of the innerliner splice just prior to and during the application of the lubricant. A pressure sensor detects high or low air pressure during the creation of the air barriers to stop the spray of lubricant should either situation be detected.

  • Patent number: 7114383
    Abstract: A method and apparatus for assessing tire performance by generating accurate, timely tire-to-surface slippage information under any operational/environmental conditions and on any road and/or off-road surface without requiring instrumentation of the roadway. The approach is capable of storing generated tire-to-surface slippage information for later retrieval and analysis and/or capable of supporting dynamic, real-time collection and dissemination of generated data. One exemplary embodiment generates and disseminates tire-to-surface slippage information in real-time that is compatible with and may be formatted for use by any consumer vehicle control system as well as external test and analysis equipment.

  • Patent number: 7108761
    Abstract: A tire and a method of securing an object thereto includes a two-piece fastening system having a first portion which is applied to an innerliner of a green tire prior to the green tire being cured and a second portion which includes an object, such as a radio frequency identification chip, attached thereto. The first portion of the two-piece fastening system is attached to the innerliner of the tire with an adhesive or by curing. The green tire is then cured and the second portion of the two-piece fastening system with the object attached thereto is then attached to the first portion of the two-piece fastening system. In an alternative embodiment, the object may be sandwiched between the first and second portions of the fastening system.

  • Patent number: 7090735
    Abstract: A method for changing the residual aligning torque (RAT) of a pneumatic tire by forming angled sipes in certain of the tread blocks in at least a pair of circumferentially extending ribs, each rib being located on an opposite side of the mid-circumferential plane of the tire. The sipes in the tread blocks in one of the ribs are formed at an inclined angle opposite to the inclined angle of the sipes in the tread blocks in the opposite rib. The RAT can also be changed by varying the depth and width of the opposed angled sipes.

  • Patent number: 7082818
    Abstract: A method and apparatus for connecting an electronic monitoring device to a pneumatic tire includes mounting the monitoring package of the monitoring device within the body of the tire or the body of a patch and subsequently connecting the power source to the monitoring package through electrical coupling. The method allows the monitoring package to be cured within the tire or the patch at relatively high temperatures while protecting the sensitive power source from the high temperatures. The use of electrical coupling to achieve the power transfer prevents the material surrounding the monitoring package from being pierced by an element that would form the direct electrical connection. The method allows the monitoring package and its antenna to be positioned in a variety of positions on or within the pneumatic tire.

  • Patent number: 7062956
    Abstract: A tire testing machine includes a spindle adapted to rotatably support a tire. The machine has a frame defining an opening that allows the tire to be loaded onto the spindle and unloaded from the spindle with the frame having an upper frame member that spans at least a portion of the opening. A hoist hanger is removably connected to the upper frame member. The hoist hanger is adapted to removably support a tire hoist that allows the tire to be supported while it is unloaded from the spindle and the machine. The hoist hanger includes a support bracket slidably disposed over the upper frame member and a support arm that extends inwardly toward the spindle of the machine. The hanger configuration provides a compact design that allows tires to be securely and safely moved with a hoist.

  • Patent number: 7056110
    Abstract: An apparatus for making reinforcement ply material wherein reinforcement elements are grouped in untwisted sets and adjacent reinforcement elements in the same set are spaced apart a distance less than the distance between adjacent sets. The apparatus includes an extruder and a die head into which the extruder extrudes an elastomeric material. The die head defines a die throat and includes a guide insert which guides the reinforcement elements into the die throat. The guide insert has passages through which the reinforcement elements pass and which are arranged in a pattern corresponding to the arrangement of the reinforcement elements in the reinforced ply material.

  • Patent number: 7052568
    Abstract: A retreading method wherein a base composition and a cap composition are applied to a carcass (10) as two ribbons (14) and (16) extruded from separate extruders (18) and (20). The ribbons (14) and (16) can be layered and applied to a ready-to-retread carcass (10) simultaneously or, alternatively, the base ribbon (14) can be applied to the ready-to-retread carcass (10) first and the cap ribbon (16) applied thereafter. The carcass (10), with ribbons (14/16) applied thereto, is then inserted into an enclosed heated mold (22) and cured to complete the retread.

  • Patent number: 7029544
    Abstract: A pneumatic tire having improved conductivity is disclosed herein whereby the tire is provided with at least one conductive pathway extending through the tread surface and contacting the tread cushion. Conductive pathways are created by introducing small volumes of high carbon black concentration. Such pathways provide low electrical resistance and dissipation of static charge accumulation on a motor vehicle.

  • Patent number: 7009506
    Abstract: A monitoring device and patch assembly includes a patch that removably and re-attachably holds the monitoring device. The patch is adapted to connect the monitoring device to a pneumatic tire when the monitoring device is held by the patch. The patch is configured to hold a monitoring device having a rounded outer surface. The patch holds the rounded monitoring device by having a resilient tube with an outlet having a diameter smaller than the diameter of the monitoring device. The monitoring device of the invention includes a feature that allows it to be removed from the patch.
