Title: Yoshiya Kubota: Innovator in Tire Vulcanization Technology
Introduction
Yoshiya Kubota is a prominent inventor based in Toyota, Japan, known for his significant contributions to tire vulcanization technology. With a total of seven patents to his name, Kubota has developed innovative methods and apparatuses that enhance the quality and efficiency of tire production.
Latest Patents
One of Kubota's latest patents is a method for vulcanizing tires and the apparatus used for this process. This method involves blowing a heating medium toward the internal surface of a tire from a supply opening positioned above the tire's equator. Additionally, a secondary pressurizing medium is also blown toward the tire's internal surface. This innovative approach prevents abnormal cooling at the lower bead of the tire, ensuring a uniform temperature throughout the tire during vulcanization. As a result, high-quality products are produced, and the time required for vulcanization is significantly reduced, leading to improved productivity and decreased energy loss. Another notable patent is the method and apparatus for inserting a green tire into a vulcanizing machine. This method centers the bead portions of the green tires relative to the bead rings of the upper and lower metal molds, ensuring precise insertion.
