Title: Akinori Kubota: Innovator in Tire Vulcanization Technology

Introduction

Akinori Kubota is a prominent inventor based in Kobe, Japan, known for his significant contributions to tire vulcanization technology. With a total of 12 patents to his name, Kubota has developed innovative methods and apparatuses that enhance the quality and efficiency of tire manufacturing.

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 directed toward the tire's internal surface. This innovative approach prevents abnormal cooling at the lower bead of the tire, thereby minimizing temperature differences within the tire. As a result, uniform vulcanization is achieved, leading to high-quality products. Furthermore, this method shortens the vulcanization time, improves productivity, and reduces energy loss.

Another notable patent is the method and apparatus for inserting a green tire into a vulcanizing machine. This process ensures that the bead portions of the green tires are centered relative to the bead rings of the upper and lower metal molds. The apparatus includes extendable and retractable sectors and chucks that move vertically to insert the bead portion of the green tire precisely into the bead ring of the tire metal mold.
