Description
What Are Separator Discs?
Separator Discs are installed on overarm separator shafts located after the slitting section of a slitting line.
Their primary functions include:
- Separating slit strips
- Guiding material during recoiling
- Preventing strip overlap
- Protecting strip edges
- Improving recoiling quality
Proper separator disc performance is essential for producing clean, uniformly wound coils.
