Title: The Innovations of Sumito Arima

Introduction

Sumito Arima is a notable inventor based in Mihara, Japan. He has made significant contributions to the field of printing technology, particularly with his innovative designs in flexographic printing.

Latest Patents

Arima holds a patent for a flexographic printing press. This invention is designed for printing on corrugated board sheets that pass between a printing cylinder equipped with a form plate and a receiving roll. The flexographic ink is stored between a doctor roll and an anilox roll, which rotate in opposite directions as they come into contact. The ink is supplied to the form plate via the anilox roll, enabling efficient printing operations. The anilox roll is driven by the printing cylinder at the same peripheral speed. Additionally, the doctor roll is controlled by a speed change drive mechanism that adjusts its peripheral speed based on the rotational speed of the anilox roll. This mechanism includes a differential gear system connected to the doctor roll, a motor for driving the differential gear, and means for transmitting the rotational force from the anilox roll.
