Innovating the quality of high-load lines with hydraulic control that balances power and precision.
【Product Features】 • Powerful and stable curvature adjustment through hydraulic control By utilizing a hydraulic cylinder, it provides greater adjustment force than manual systems. It enables powerful and stable curvature (bow) adjustments even for wide and high-tension sheets. • Adjustable for optimal wrinkle removal effect even during operation Similar to manual systems, the degree of curvature can be adjusted without stopping the equipment. It responds instantly to changes in sheet condition and operating circumstances, maintaining the highest quality at all times. • Versatile dual-functionality as a straight roll By setting the degree of curvature (bow) to zero, it also functions as a complete straight roll. It performs various roles with a single unit, enhancing the versatility of the equipment.

イプロスなどのグローバル展開も見据えたBtoBサイト向けの英語翻訳ですね！ 海外の技術者や購買担当者にも「技術の凄さ」がダイレクトに伝わるよう、製造業の専門用語（Web＝連続シート、Yield＝歩留まりなど）を使って、プロフェッショナルかつインパクトのある英語に仕上げました。 Eliminate Wrinkles & Shrinkage! "OS Expander Roll" by Japan's Pioneer Manufacturer Fundamentally solve the issues of wrinkling and shrinking in all web manufacturing processes, including film, paper, non-woven fabric, and metal foil! Osaka Senshoku Kikai is the specialized manufacturer that successfully produced Japan's first domestically made expander rolls. We dramatically improve your yield rate without damaging the material. ■ Our 3 Key Strengths 1. Ultra-High Precision "Rubber Surface Grinding" We precision-grind the rubber surface while the roll is in a bowed state. This achieves an exceptionally high level of accuracy that competitors cannot replicate. 2. Motor-Free Design No motor is required. The roll rotates smoothly using only the web tension, significantly reducing both running costs and equipment load. 3. The Repair Experts With over 70 years of experience, we repair and refurbish expander rolls from any manufacturer, domestic or international. We bring your existing equipment back to life. ■ Proven Track Record Featured extensively on major Japanese TV networks (NHK, Fuji TV, etc.). We also exhibited at the Expo 2025 Osaka, Kansai, showcasing the essence of our wrinkle-removal technology to the world.
