Large parent rolls are slit to narrow widths using precision slitting blades to ensure burr‑free, clean edges. The narrow web is rewound under constant tension to prevent telescoping. Each roll is visually inspected for edge quality. The adhesive coating is applied uniformly across the narrow width to avoid glue starvation on the edges.
