Title: Innovations of Shuichi Tsukada

Introduction

Shuichi Tsukada is a notable inventor based in Hiratsuka, Japan. He has made significant contributions to the field of tire manufacturing, holding a total of five patents. His work focuses on innovative methods and designs that enhance the performance and efficiency of pneumatic tires.

Latest Patents

One of Tsukada's latest patents is a method for manufacturing a pneumatic tire. This method includes the steps of intermittently crimping volume adjusting members on both side sections of a sheet inner liner material in a longitudinal direction beforehand. It also involves winding the inner liner material on an outer peripheral side of a forming drum and winding a sheet carcass material on an outer peripheral side of the inner liner material. The process culminates in forming an unvulcanized tire containing both the inner liner material and the carcass material, followed by vulcanizing the unvulcanized tire. The volume adjusting members are strategically arranged in a tire circumferential direction between the inner liner material and the carcass material.

Another significant patent by Tsukada is for a pneumatic tire featuring an asymmetric tread with a subgroove apex offset. This design includes a tread comprising a plurality of straight-linear main grooves extending in the circumferential direction of the tire, along with subgrooves that extend to the shoulder ends of the tire. The subgrooves cross the main grooves at an inclination, featuring a curved portion that is convex in the direction of rotation of the tire. This innovative design enhances the tire's performance by optimizing the ground-contact area.
