Title: Noboru Kusaba: Innovator in Steel Cord Technology

Introduction

Noboru Kusaba is a notable inventor based in Tochigi-ken, Japan. He has made significant contributions to the field of steel cord technology, particularly in applications for pneumatic tires. With a total of 2 patents, his work has had a lasting impact on the industry.

Latest Patents

Kusaba's latest patents include innovations such as a steel cord having a flat side surface portion and a method of manufacturing the same. This steel cord is produced by forming a series of bends on each filament that constitutes an outer layer sheath. The process involves twisting these filaments while aligning the bends in the cord axial direction and subjecting the cord side surfaces to compression processing. The result is a steel cord with flat side surface portions, where the filaments are positioned in the same plane. This design is particularly useful for reinforcement plies in pneumatic radial tires, ensuring that the flat side surface portions are mutually parallel.

Another significant patent involves a method for producing a steel cord from three to six steel filaments, which are coated to enhance adhesion to rubber. This method includes preforming the filaments by twisting them together to create an open-structure steel cord. The cord is then passed through a flattening apparatus, which bends it vertically or horizontally, optimizing it for use in rubber products with flat sections.
