It has been almost 30 years since BTG innovated and developed the first High-performance coating blade in the world. High-performance coating blade can improve paper quality, decrease web breaks, blade changes and eliminate running-in time

BTG Duroblade overcome the performance degradations caused by rapid wear-and-tear on steel components, delivering clear performance improvements and better quality coated paper and board products. Our blade tips are treated with the materials of ceramics, ceramic-metal compounds to enhance coated paper surface, smoothness, gloss and fiber coverage. This is turn leads to significant, sustainable gains in business performance.

In this paper, I describe a history of HP-blade development in BTG. Also explain how coating blades make influence on coated paper surface quality at a technical stand point.
