For the production of high-performance films! Suppressing scratches and waviness with micro-groove rolls.

Solve issues such as slipping, weaving, and poor yield with just a roll exchange! Includes processing and application examples. *Exhibited at FILMTECH JAPAN.

【Exhibition Information】 We will be exhibiting at the "High-Function Material Week 12th FILMTECH JAPAN (2024/5/8 - 5/10)." ■Venue: Intex Osaka Hall 4 ■Booth Number: 14-15 ★We will also conduct a cleaning demonstration of brought-in work using the non-contact shock wave cleaner "Wavy." *Demonstration target: Films with a thickness of up to 150μm and dimensions of approximately 100x150mm. Our micro-grooved rolls, which have uniform and fine groove processing on the roll surface, are an essential technology for the production of high-value-added, high-function films and have been adopted by many companies in their production lines. Improvement results can be achieved simply by replacing the free roll without modifying the equipment, and it is also possible to eliminate wrinkles. With appropriate groove design according to production conditions, it is possible to maintain the same grip state during production as during stalling, thereby suppressing wandering, tension wrinkles, and scratches. Based on our uniquely developed design and processing technology for non-transferable fine grooves, as well as our extensive experience in designing, manufacturing, and modifying RtoR equipment, we propose better problem-solving methods. We also have numerous successful implementations of nipless feed-tension cuts and underwater transport. Please feel free to contact us first.
