Stable quality that withstands wear for the production line of high-load metal sheets.
【Product Features】 • Excellent wear resistance that withstands high tension and high load environments The surface is coated with highly wear-resistant urethane rubber. With a tough design that supports a maximum tension of 9000 kgf, it minimizes wear even in high-load production lines such as steel plates and metal foils, ensuring stable operation over a long period. • Ideal for manufacturing lines of steel plates and metal foils Its outstanding durability is particularly effective for wrinkle removal of sheet products that exert significant load on rolls, such as steel plates and thick metal foils. It achieves reliable quality even under harsh conditions. • Groove processing option to further enhance grip performance It is also possible to apply groove processing to the urethane rubber surface according to the characteristics of the products handled by customers. This improves grip performance and meets the needs of customers seeking more reliable wrinkle removal effects.

Company information
We are Osaka Senshoku Kikai Co., Ltd., the pioneer and first manufacturer to domestically produce "Expander Rolls" in Japan. We provide fundamental solutions to eliminate "wrinkles," "shrinkage," and "slippage" in Roll-to-Roll web handling processes for films, metal foils, and non-woven fabrics. [Our Core Strengths] ◆ Japan's Only "Precision Curved Grinding" Our unique technology enables precision grinding while the roll is in its curved state. This eliminates vibration even on high-speed lines for ultra-thin films, dramatically improving your production yield. ◆ Ultra-Low Torque "Drive-less Design" No motor required. Our rolls rotate smoothly driven solely by the web's conveying force, effectively preventing slip scratches on your products. ◆ "Special Materials" & "Retrofitting" Fully compatible with special materials such as "fluorine rubber" (FKM), which is essential for high-temperature and adhesive lines. We also have an extensive track record of replacing/retrofitting other manufacturers' flat-type rolls with our curved rolls. ◆ Repair & Refurbishment for All Brands We provide repair and restoration services for expander rolls from any manufacturer, both domestic and international. [Proven Track Record] Since our founding in 1951, our cutting-edge technology has been featured on major national TV news programs and exhibited at the Expo 2025 Osaka, Kansai. Beyond standard catalog specifications, we promise to offer the optimal proposals and solve your line's most difficult challenges. Please feel free to contact us.
