WIDE-COIL STRIP PRODUCTION
YAWEI slitting line
The YAWEI line slits standard stainless steel coils into strips from 22 mm wide. Thickness-specific knife setups, simultaneous film application and controlled recoiling support repeatable dimensions and protected surfaces.
Protect both surfaces
Simultaneous top-and-bottom film application protects the material during processing and subsequent handling.
Paper interleaving
Recoiling supports paper interleaving, including a double-paper configuration for order-specific surface protection.
Controlled recoiling
Coil edge alignment is specified within ±1 mm, with a recoiling telescoping tolerance of ±2 mm.

Slit-width tolerance by thickness
| Thickness (mm) | Width tolerance |
|---|---|
| 0.3–1.0 | ±0.1 mm |
| 1.2–3.0 | ±0.05 mm |
For thicknesses above 1.0 and below 1.2 mm, the width tolerance is confirmed with the order.
Number of slit strands
| Thickness (mm) | Maximum strands |
|---|---|
| 0.3–1.0 | 22 |
| 1.1–2.0 | 15 |
| 2.1–3.0 | 10 |
Strand count depends on the thickness band, strip widths and knife setup.
Intermediate thicknesses outside the stated bands and special materials require technical review. Maximum speed and strand count are confirmed for the selected setup.
