Slitting Machines — Types, Configurations & Parameters
Engineering reference for industrial slitting machine types, configurations, tension control systems, and key operating parameters.
Machine Types
| Type | Best For | Tension Control | Typical Speed |
|---|---|---|---|
| Log Slitter | Large roll conversion, paper | Basic | 100–400 m/min |
| Rewind Slitter | Precision film, foil, battery materials | Individual web tension | 50–600 m/min |
| In-line Slitter | Continuous production lines | Line-synchronized | Up to 800 m/min |
Key Parameters
- Knife clearance: See slitter knife guide for material-specific values
- Knife overlap: Typically 0.5–2mm depending on material thickness
- Web tension: Critical for film and foil — typically 5–50 N/m
- Rewind tension taper: 20–30% taper prevents telescoping

What is a slitting machine?▼
A slitting machine (also called a slitter rewinder) is industrial equipment that unwinds a master roll of material, cuts it into narrower widths using rotary knives, and rewinds the slit strips into individual rolls. Used in metal, film, paper, and foil processing industries.
What is the difference between a log slitter and a rewind slitter?▼
A log slitter cuts a large parent roll without rewinding — the output is a set of cores that are then cut transversely. A rewind slitter (slitter rewinder) unwinds and rewinds each slit strip independently, providing better tension control. Rewind slitters are preferred for precision materials like lithium battery separators.
What speed can a slitting machine run?▼
Slitting machine speeds range from 50 m/min for precision film slitting up to 600 m/min for high-speed paper or foil lines. Metal slitting is typically limited to 100–300 m/min depending on material hardness and strip width.
