The stamping press in a body‑shop pulls an opaque paper roll through the die cavity, where the sheet acts as a disposable barrier that absorbs lubricating oil and catches metal shavings, keeping the press tooling clean and preventing contamination of the freshly formed sheet metal. As the roll unwinds, the paper feeds directly into the gap between the upper and lower dies, providing a thin, non‑slipping layer that protects delicate surface finishes while tolerating the high temperatures generated by rapid forming cycles. Operators can replace the roll in minutes, minimizing downtime and avoiding the need for costly cleaning procedures after each batch. Down‑stream, the same type of roll is fed into the paint‑shop wrapping stations, where it envelops newly sprayed body panels before they enter the curing oven, shielding them from dust and stray particles that could mar the lacquer. By serving as a consumable protective liner in both forming and finishing stages, the opaque paper roll supports continuous, high‑throughput vehicle assembly while preserving part quality and reducing rework.
