  • Publication number: 20220203637
    Abstract: Systems and methods of machine learning for splice improvement. A system can receive, from one or more sensors, one or more values corresponding to manufacture of a tire by the one or more pieces of tire manufacturing equipment. The systems can determine one or more metrics based on the one or more values. The systems can generate a matrix based on the one or more values and the one or more metrics. The systems can predict, via input of the matrix into a machine learning model, a value for a splice tolerance metric. The systems can determine, based on the value for the splice tolerance metric, a parameter of at least one piece of equipment to adjust. The systems can provide a command to adjust the piece of equipment responsive to the value of the splice tolerance metric.

  • Publication number: 20220106421
    Abstract: A process for preparing a polydiene having increased viscosity and reduced cold flow that includes polymerizing a conjugated diene monomer in the presence of a lanthanide-containing compound to form an intermediate polymer, and then adding a non-organometallic trimellitate ester compound as a coupling agent to raise the viscosity of the intermediate polymer. The coupling agent is added to the intermediate polymer mixture in an amount of about 0.01 to about 0.15 parts per hundred monomer (phm) of the starting monomer amount.

  • Patent number: 11255755
    Abstract: A method of testing a tire is employed in an enclosed system having a drum enclosure connected to a tire enclosure by flexible bellows, the enclosed system configured such that a tire inside the tire enclosure abuts a drum inside the drum enclosure. The method includes rotating the drum at a first angular velocity, thereby causing the tire to rotate at the first angular velocity. The method further includes measuring a temperature at a first location adjacent the tire and blowing cool air into the tire enclosure when the measured temperature exceeds a predetermined temperature threshold. The method also includes measuring a humidity level at a second location and adding moisture in the tire enclosure when the measured humidity level falls below a predetermined humidity threshold.

  • Patent number: 11225112
    Abstract: Provided is a pneumatic tire comprising a tread, sidewalls, a belt, and dimpled patterns, wherein each dimpled pattern is adapted to modify air flow and temperature. The tread defines the outward surface of the tire and extends in a radial direction, a circumferential direction, and a lateral direction. Each sidewall extends radially inwardly along a curved path from the tread to a bead and defines a lateral surface having maximum lateral extent. The belt extends under the tread. Each dimpled pattern is a surface treatment etched from a sidewall maximum lateral extent over a belt edge and onto the tread. Each dimpled pattern surface treatment modifies air flow at 180 mph over the tire to turbulent flow, and reduces steady state operating temperatures of the sidewalls.
