Not all paper behaves the same in a sheeter.
Running different grades with one fixed setup is one of the most common reasons for defects, unstable operation, and unnecessary downtime.
In real production, cutting performance is closely tied to the physical properties of the paper—weight, stiffness, surface structure, and moisture behavior all play a role. Ignoring these differences leads to inconsistent results.
Why Paper Grade Matters
Each paper grade responds differently to tension, cutting force, and transport conditions.
A setup that works well for one material may cause problems for another.
This is why parameter adjustment is not optional—it is necessary for stable production.
Typical Behavior by Paper Type
1. Lightweight Paper (28–80 gsm)
Thin paper is flexible and highly sensitive to tension changes.
Common issues include:
- wrinkling during transport
- web instability at higher speeds
- risk of web breaks under excessive tension
To run lightweight grades properly, the system must operate under low, stable tension, with smooth conveying and minimal disturbance.
2. Heavy Board and High GSM Paper
Thicker materials behave very differently.
They require:
- higher and more stable cutting force
- rigid mechanical support during cutting
- precise synchronization to avoid deformation
If the cutting force is insufficient or unstable, problems such as rough edges or incomplete cuts can occur.
3. Coated Paper
Coated surfaces introduce another layer of complexity.
While structurally stable, they are more sensitive to surface damage.
Typical risks include:
- scratching during transport
- coating cracks at the cut edge
- visi
