■ Versatile Process Applications: Suction rolls replace the Nip Roll and act as a leading roll in
various processes, including secondary battery electrode coating, roll pressing, slitting, and
notching. They are also used in optical film production lines, where they substitute the Nip Roll in
roll-to-roll processes.
■ Safety and Defect Prevention: The suction roll prevents secondary defects on good-quality
electrode sheets by keeping the roll free from contaminants. It also reduces the risk of workplace
accidents like pinching and entanglement.

■ Reduced Maintenance Costs: The suction roll is made with a metal-plated surface, which
provides excellent durability for long-term use. Its simple maintenance also helps reduce costs.
Additionally, there are mesh rolls that can be used for delicate materials and variable suction rolls
that allow you to adjust the suction area to match the width of the material.

Our Company's Suction Roll
A precision roll device that securely holds fast-moving webs with powerful suction. It can process
thin, sensitive materials like paper, film, and secondary battery electrodes smoothly and without
wrinkles.
Why is it necessary?
As production line speeds increase, webs can flutter or lift, but the suction roll prevents this by
stabilizing the material, protecting quality. This leads to reduced defect rates, improved
productivity, and cost savings.
Our Product's Strengths
Optimized for Dry Electrode Processes: Minimizes dust generation and maintains cleanliness.
Precision Control: Provides uniform tension and speed for high-quality webs.
Diverse Applications: Suitable for secondary batteries, paper, film, packaging, semiconductor
materials, and more.
By integrating our suction rolls into your production line, you can gain a competitive edge in both
quality and productivity.
1. Technology Overview
A Suction Roll is a precision roll device that uses an internal vacuum structure and a porous
surface design to hold and stabilize moving webs. It plays a key role in Dry Electrode
Manufacturing, ensuring the stable transport of the electrode web and the uniform application
of powder.
2. Key Technical Features

Optimized Vacuum Suction: Minimizes web lifting even during high-speed operation.
Precision Tension Control: Prevents deformation and wrinkling of the electrode web.
Cleanliness Maintenance: Controls dust and prevents foreign particle contamination, making it
suitable for cleanroom environments.
