Polyurethane Rolls
  • The World’s First Polyurethane Roll Helped to Spread the Yamauchi Name.

    In 1963, Yamauchi successfully developed the polyurethane roll for papermaking equipment as the first in the world. Named High Top Roll. This revolutionary roll offers dramatically improved performance and durability, and made the name “Yamauchi” known throughout the world. Since then, we have been expanding our product line and developing various products to respond to the trend toward high-speed, large-scale and high-quality production.

CHARACTERISTICS

Long-Life Design with Significantly Improved Abrasion Resistance and Pressure Resistance.

Thanks to polyurethane’s high resistance to abrasion, pressure and chemicals, High Top Roll has stable physical properties, such as shape and hardness, over a long period of time. The double-structure, with a polyurethane layer and a base layer, also improves the strength of adhesion to the shell. As a result, High Top Roll offers a long life unmatched by any other product. Used as a suction roll in the press part and as an applicator roll in the size part, High Top Roll offers high performance and excellent reliability that have achieved high evaluation in the world.
