Description
What Are Rubber Stripper Rings?
Rubber Stripper Rings are essential components in metal slitting lines.
Installed between slitter knives and spacers, they perform several critical functions:
- Material stripping
- Strip tension control
- Surface protection
- Vibration reduction
- Stable strip tracking
Proper stripper ring performance directly affects:
- Strip quality
- Surface finish
- Slitting accuracy
- Production efficiency
Composite Construction
