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.
External burrs reduce surface quality, while internal burrs block smooth flow inside pipes. With external burr scraping blades and specialized internal deburring tools, both issues are solved efficiently. This ensures tubes have a clean surface, smooth inner walls, and excellent performance — making your pipe products stronger, safer, and more durable.
A roofing sheet roll forming machine transforms steel coils into corrugated, trapezoidal, tile, or double-layer profiles with precise shapes and smooth finishes. Widely used in residential, industrial, and commercial construction.Our machines help manufacturers reduce costs while producing durable and waterproof roofing panels for modern projects.
Ferrite used to guide and concentrate high-frequency current. The impeder is composed of ferrite rods, a protective sleeve, and a cooling tube. Installed inside ERW tube mills, it focuses the welding current on the seam, thereby improving efficiency and weld quality.
Understanding material compatibility in steel pipe making machine operations is crucial for ensuring product quality, equipment longevity, and production efficiency.
Understanding material compatibility is foundational to maximizing the performance of solid state welding machine systems, ensuring strong, durable welds while protecting equipment integrity.
Understanding the coil width range capabilities of a metal slitting line is essential for selecting equipment that aligns with diverse material processing needs, from narrow strips to wide coils.
