When a freshly painted car body exits the paint booth, residual spray and micro‑particles must be cleared before the panel moves to the drying tunnel. A dedicated cleaning blade mounted on the conveyor’s upstream station sweeps the surface, spreading a thin film of solvent and physically removing excess material. The blade’s flexible edge follows the contour of the body, preventing streaks that could compromise subsequent coating layers or cause defects in downstream welding operations. Because the wiping action is synchronized with the line’s speed, the component can be exchanged quickly during shift changes, keeping the line’s throughput stable. In addition to body‑shop applications, the same type of cleaning blade is employed on high‑pressure wash stations in plant maintenance, where it scrapes oil film from large‑diameter pipes before inspection. By providing a reliable, repeatable cleaning step, the blade enables manufacturers to maintain surface quality without slowing the assembly flow.
