Title: Chihiro Sawada: Innovator in Tire Manufacturing Technology
Introduction
Chihiro Sawada is a notable inventor based in Kodaira, Japan. He has made significant contributions to the field of tire manufacturing, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
His latest patents include an "Apparatus for building tire and method for using same." This apparatus features an outer shaft, an intermediate shaft, and a center shaft that are disposed coaxially with each other. The building drum is supported on the outer shaft and has a uniform outer diameter over its entire length. The design includes means for rotating these shafts, which are located on one side of the building drum. The building drum consists of two axially divided drum portions that can move in mutually approaching and separating directions, allowing for radial expansion and contraction. The intermediate shaft is reciprocably connected to one drum portion, which is drivably connected to the other drum portion for reciprocal movement. Additionally, cam members facilitate the radial transformations of the drum portions. The apparatus is powered by a first motor connected to the intermediate and center shafts, and a second motor connected to the center shaft.
Another significant patent is related to a tire manufacturing method and tire. This method focuses on producing a side-reinforced type runflat tire, where side reinforcing rubbers with crescent-shaped sections are placed between a carcass and an inner liner. The first drums used for attaching the side-reinforcing rubbers are designed to maintain a consistent diameter along the axial direction. The operations of expanding the first drum and the approaching of the bead gripping rings are synchronized to ensure a high-quality tire production process.
