The Waybee is a blowerless, non-contact shockwave film cleaner. It features a unique cleaning head mechanism (patented) that strikes the shockwaves generated against the air boundary layer accompanying the workpiece, while simultaneously generating wind speeds exceeding 30 m/s near the substrate without a blower. This allows for the efficient removal of "killer dust" below 10μm and dust particles up to several hundred micrometers, using a small dust collector to suction up the lifted dust. It has a proven track record of removing dust even from films with high dust content. While achieving high-efficiency cleaning, it eliminates the need for large blowers or suction machines, significantly reducing both initial and running costs. 【Features】 - Energy-saving, space-saving, and low noise - Contributes to SDGs - Rental machines available (limited sizes and quantities) - Customization consultations available - Real machine testing possible with our test equipment (maximum film width of 700mm) For more details, please contact us.

We would like to introduce our "Special Micro Bingham Roll." It can suppress NIP wrinkles during feed rolls and product winding. With the "air release + expansion effect" during winding, it simultaneously prevents rewinding and lateral slippage during low-tension winding. 【Features】 ■ Can be produced at the same cost as general-purpose NIP rolls ■ No special design required for each brand ■ Can replace two-layer rubber ■ Solves the issue of lateral scratches when using low-hardness rubber ■ No excessive tension is needed to achieve winding hardness *For more details, please refer to the PDF document or feel free to contact us.

【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.

A roll that has been uniformly processed with fine grooves on its surface is called a micro-groove roll. This technology is essential for the production of high-value-added, high-functionality films. We have independently developed processing technology for fine grooves that do not transfer and edge processing technology that prevents the generation of scratches, and we are pleased to offer these to you. **Effects of Micro-Groove Rolls** - Enables an increase in film transport speed at the same tension. - Improves winding quality by stabilizing the film transport posture. - Allows low-tension operation without reducing transport speed. - Effectively prevents scratches. - Demonstrates wrinkle-stretching effects when used in combination with concave shapes. *For more details, please download the PDF or contact us.*

The central part of the roll, which is narrower than the ends, is referred to as a concave shape. By adding a concave shape to the micro-groove roll, it exhibits a wrinkle-stretching effect. The maintenance of the friction coefficient through fine groove processing allows the film's expansion function to be imparted regardless of the roll material or the presence of drive. Note: Concave rolls without fine groove processing have almost no wrinkle expansion function. Processable roll materials: both metal rolls and rubber rolls can be processed. Concave amount: 0.1 to 0.5%/m, determined by film material, thickness, and width. [Effects of Concave Rolls] - Effective for low-tension transport and wrinkle stretching of ultra-thin films. - Effective for wrinkle stretching of films that are weak in the TD direction. - Exhibits excellent effects on wrinkles that could not be handled by flat EXP, baribow EXP, or pinch rolls. - With free rolls, the wrinkle-stretching function can be imparted, enabling cost-effective and high-quality equipment modifications. *For more details, please download the PDF or contact us.

The traditional grooved rubber rolls, even when using a rigid film, typically cannot achieve sufficient elastic deformation of the rubber at a tension of around 200N/m, resulting in a lack of wrinkle-removing effect. Additionally, due to the grooves being too wide, they can cause groove transfer and wrinkle formation when winding thin or fragile films, leading to cases where their use is discontinued. For those who feel that the wrinkle-removing effect of traditional grooved rubber rolls is insufficient, we propose the Micro Bingham Roll. **Effects of the Micro Bingham Roll** - It demonstrates a wrinkle-removing effect even at low tension due to the minute cross-sectional deformation of the roll surface. - The fine groove width makes groove transfer less likely, allowing for use on contact rolls. - When used on contact rolls, it enables winding at lower tension and lower contact pressure, achieving better winding than before. - Adding a concave shape to the Micro Bingham Roll increases the coefficient of friction compared to metal rolls, resulting in a greater wrinkle-removing effect. *For more details, please download the PDF or contact us.*
