Title: Yasuhiro Tsutsumi: Innovator in Papermaking Technology

Introduction

Yasuhiro Tsutsumi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of papermaking technology, holding 2 patents that showcase his innovative approach to solving industry challenges.

Latest Patents

One of his latest patents is an elastic belt for papermaking calender. This invention addresses the conflict between structural strength and flexibility in conventional elastic belts. It reduces manufacturing time by utilizing a belt where the paper sheet-facing side of a base body is covered by a high molecular weight elastic layer. This layer consists of a dense, first high molecular weight elastic layer and a second layer with a multitude of small voids of almost the same size. This design achieves flexibility while ensuring that the dense surface layer adapts to the ruggedness of the paper sheet.

Another significant patent is for a calendering belt that is relatively low-cost yet offers excellent heat resistance and durability. This belt comprises a central portion and left and right side portions. The side portions are made from high molecular weight elastic material that has greater heat resistance than the central portion. The central portion is composed of high-molecular elastic material, which has higher durability than the side portions. The design effectively intercepts heat from the calender roll, preventing it from transmitting to the central portion of the calender belt.
