Pre-setting air knife pressure on product changes
Even before a new coil reaches the air knife position, theautocontrol system can instruct the air knife control to run the best parameter set which has been recorded in a previous production. The product changeover will be exactly at the defined length position, e.g., weld seam. This results in significant reductions in scrap during product changeover. Additionally, fast changeover can provide flexibility in planning production "campaigns" for the galvanizing line.

I cannot understand the word "campaign" in current context.
