Key takeaways
- Paper machines often run 55 to 80 percent OEE.
- The big losses: web breaks, grade changes, and clothing/roll changes.
- As a continuous process, availability dominates the OEE picture.
- A single web break can cost many minutes of re-threading.
Pulp and paper is a capital-intensive continuous process: a fast, wide sheet runs through forming, pressing, drying and reeling without pause. When the sheet breaks, the machine stops until it is threaded again, so availability is the dominant OEE factor and the web break is the defining loss.
What's a good OEE in paper?
Paper machines commonly run 55 to 80 percent OEE against the 85 percent reference, with the better mills higher. The biggest separators are web-break frequency and grade-change efficiency, far more than raw speed. Calculate your OEE.
The biggest losses in paper & pulp
| Loss | Why it's big in paper | OEE factor |
|---|---|---|
| Web breaks | Each break stops the machine until the sheet is re-threaded, and broke is recycled | Availability |
| Grade & basis-weight changes | Transitions create off-spec production and lost time | Availability / Quality |
| Clothing & roll changes | Felts, wires and rolls need scheduled changes | Availability |
| Drying & moisture constraints | The dryer section limits speed; moisture variation hits quality | Performance / Quality |
| Quality losses | Holes, breaks and profile variation create off-spec reels | Quality |
Translate minutes lost per break and breaks per day into an annual cost.
What downtime costs in paper
The asset is huge and runs around the clock, so every minute of unplanned downtime is expensive and a frequent-break machine loses serious capacity over a year. Energy in the dryer section adds to the cost of any instability. Estimate your downtime cost.
How leading paper mills improve
- Reduce web breaks by finding their true causes (furnish, tension, profile, condition).
- Streamline grade changes with standard transitions and tight control.
- Protect clothing and rolls with predictive maintenance (PdM).
The partner we recommend, , reads stops from the machine and uses computer vision to show the true cause of breaks and stops, then routes a work order. It is EU-built with EU data residency and holds ISO 27001 / 20000-1 / 9001 (supports audit-readiness). Fabrico is a partner we recommend; the tools here are free regardless.
Does OEE work for a continuous process?
Yes, with availability as the dominant factor. Pair OEE with web-break frequency and grade-change time, which tell the real story on a paper machine.
What is the single biggest lever?
Web-break reduction, almost always, because each break is lost production and recycled broke. Finding the true cause of breaks is the key. See the six big losses.
Does this cover converting and tissue?
The continuous-web dynamic carries across machine-glazed, tissue and converting lines, though break causes and speeds differ. See also Packaging & Converting.
