• Clean : Quality Improvement
  • No Scratch, No Dent: Foreign particles are absorbed into the roll body, reducing scratch and dent occurrence.
  • No Rubber Powder: No rubber powder generated by strip-edge burrs.
  • Slip Mark: No slip marks even at high line speeds due to zero strip slip.
  • Oil Stain, No Carbon Deposit: Complete wringer performance removes all surface contamination, ensuring a clean strip surface.
• Efficient : Productivity Increase
  • Reduced roller replacement frequency improves productivity and roller maintenance efficiency.
  • Lower defect rates increase yield.
  • Higher line speed capability boosts productivity (stable at 500–600 MPM, with no slip even up to 1600 m/min).
  • Significant improvement in productivity for oiled products, enabling maximum throughput.
• Saving : Cost Reduction – Total Maintenance Cost Reduction
  • Long service life: 4–8 times longer than conventional rolls, reusable after surface regrinding, reducing maintenance cost.
  • Oiling efficiency: Excellent fiber adhesion enables uniform oil coating. Over-coating at the edge or coil
  • slip is minimized, reducing oil loss. Oil usage is cut to approximately half compared to conventional rolls.
• Safe : Accident Prevention
  • Prevents slipping accidents in the yard caused by excessive oil, ensuring a safer and cleaner work environment.
  • No strip slip and fewer roll replacements reduce accident risks, supporting a safe workplace.

• Non-Tex Rolls (Pinch Roll, Wringer Roll, Feeder Roll) used in the washing units of OEM manufacturers
• Utilization of OW90H Non-Tex fabric through a technical partnership with Toho Yogyo (Japan)

1. Non-Woven Disk: Each disk is compressed individually, and the roll surface contacts the strip during operation
2. Shaft: Metal roll shaft secured in bearings during use
3. Flange: Compresses and fixes the non-woven disks onto the shaft
4. Ring: Functions as a stopper

Total vacuum system that connects the vacuum pressure formed by the vacuum pump to the roll and allows the solution on the roll surface to be absorbed and discharged

Unlike conventional Non-Woven Rolls, which rely on surface pressure to achieve wringing through suction and discharge, the Vacuum Suction Roll utilizes a hollow shaft structure. This design evenly distributes the negative vacuum pressure inside the shaft across the entire surface, enabling efficient absorption of the solution. As a result, the Vacuum Suction Roll offers significantly superior wringer performance compared to traditional Non-Woven Rolls.

※ Applicable Rolls: Wringer Roll, Squeeze Roll, Wiper Roll

1. The roll compresses to expel the solution contained within it.
2. As the roll returns to its original state, it absorbs the residual solution from the strip.
3. The absorbed solution is then expelled through the piping located on the side of the shaft.

• Clean Surface
  • Enables complete absorption of solution in the edge areas, which was previously restricted with Rubber Roll / Non-Woven Roll.
  • Significantly reduces solution residue on the strip surface (below 1g/m²).
  • Allows the use of the maximum spraying volume of cleaning oil, which was previously limited due to residue on the strip surface, thereby enhancing strip surface quality.
• Efficiency
  • Achieving complete removal of liquid from the strip surface, thereby maximizing production efficiency through extended roll exchange intervals (Line Speed Up).
• Saving
  • The cleaning oil/solvent suctioned by the vacuum roll can be reused, leading to a reduction in solvent replenishment and replacement costs.
  • Reduction in electricity and steam consumption by eliminating the need for air blowers and dryers at the rear of the vacuum roll.
  • Lower maintenance costs resulting from the extended lifespan of the wringer roll at the front.
  • Decreased opportunity costs associated with line downtime due to longer roll exchange intervals.
• Safe / Clean
  • Elimination of solvent residue and splashing, improving the work environment and reducing safety risks.
  • Improved factory conditions by discontinuing air knives on strip edges, reducing splashing and noise.

• Steel and Nonferrous Metals
  • CAL, CGL, CCL, STS APL, BAL and other continuous production lines requiring complete solution control at Spot : Degreasing, SPM, TL, Final Rinse exit
  • Wiper Rolls used in Rolling Mill processes such as ZRM and TRM
  • Film and foil ultra-thin strip production lines
• Automotive
  • Washing Unit Final Roll within Press Lines

Manufactured using special high-performance non-woven materials, this Non-Woven Roll is suitable for various applications in high-temperature zones (Max 400°C).

The strength and heat resistance of aramid fibers allow use in rolls requiring excellent thermal resistance and abrasion resistance.

• Excellent Heat Resistance
  • Maintains more than 50 percent of its room-temperature strength at 250°C, with a thermal decomposition point of 500°C.
• High Abrasion Resistance
  • Can be applied as a countermeasure against wear on guide rolls caused by contact with strip edges.
• Secured Friction Coefficient
  • Effective as an anti-slip solution for CPC Rolls, enabling stable operation at high line speeds.
