Solve the challenges of the roll surface while simultaneously improving productivity and maintainability.
【Product Features】 • Excellent non-stick properties to prevent adhesion to roll surfaces The superior non-stick and slippery properties of fluororesin (Teflon) are applied to the rolls. This prevents the adhesion of adhesives, inks, and debris, significantly reducing cleaning efforts and improving productivity. • Wide compatibility from expanders to specially shaped rolls Our expander rolls can be coated, and we can also process special shaped rolls such as metal rolls and crown rolls used by our customers. This enhances the performance of various rolls. • Conductive types available for effective static electricity countermeasures We also offer conductive type tubes that suppress static electricity, which can be a problem in film and paper production lines. This helps prevent dust adhesion to products and reduces the risk of electric shocks.

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.
