🎯 Main Purposes of Slitting Separators

Function Category	Description
1. Separation	Separates the slit strips from each other to prevent overlapping, tangling, or rubbing during line operation or recoiling.
2. Guiding	Helps guide the strips along an accurate path, ensuring neat edges and proper alignment during recoiling.
3. Support	Provides physical support for thin or soft materials (e.g., stainless steel, aluminum), preventing sagging or vibration.
4. Surface Protection	Rubber-coated separators prevent scratches, dents, or marks on the edges of the metal strips, improving surface quality.
5. Improved Product Quality	Proper use of separators helps maintain consistent strip width and tight, uniform coils, increasing product yield.

🛠️ Usage & Maintenance Guidelines

✅ Usage Guidelines

Correct Installation Orientation: Ensure the separator disc is perpendicular to the knife and fits tightly on the shaft with no play.
Proper Spacing: Match separator thickness to slit strip width and spacing requirements to prevent entanglement.
Avoid Overloading: Excessive load may damage the separator or misalign the knives, reducing slitting quality.
Prevent Contamination: Keep the line clean; avoid metal shavings, oil, or debris that can damage the separator surface.

🧽 Maintenance Tips

Regular Wear Inspection: Especially for coated separators—replace aging rubber in time.
Clean Shaft and Separator Surfaces: Prevent rust or jamming.
Store in Dry Conditions: Avoid moisture to prevent rusting of metal components.
Track Service Life and Replacement: Helps with production planning and quality assurance.

📎 Additional Recommendations
- For stainless steel or aluminum (scratch-sensitive materials), rubber-coated separators are recommended.
- For heavy-duty or high-frequency use, choose nitrided high-hardness steel.
- Custom designs available: non-standard sizes, special edges (e.g., tapered, anti-slip grooves) can be tailored to specific process requirements.

Slitting Knives and Slitting Spacers FAQs

What is a Slitting Separator?

A slitting separator is a guiding and isolating component installed on both sides of the top and bottom slitter shafts. It is positioned between the slit strips to prevent them from touching, tangling, or scratching each other during line operation or recoiling.

What’s the difference between a Separator and a Spacer?

A Separator is used to physically separate and support the slit strips and guide them during operation. A Spacer is used to accurately set the spacing between knives to ensure the correct strip width.

Where are separators installed, and how is spacing set?

Separators are mounted on the shafts on both sides of the knives and placed between the finished slit strips. Spacing is based on strip width, knife arrangement, and rewinding tension, typically leaving a 0.2–1 mm clearance between strips.

How should separators be maintained?

Regularly clean dust, oil, or metal debris from the surface Store in a dry environment to prevent rust Check rubber coating for aging, hardening, or cracks and replace as needed Inspect bearings (if equipped) for smooth rotation

Can separators be customized?

Yes. You can customize outer diameter, inner bore, thickness, and coating material based on shaft size, strip width, material type, and specific line requirements.
