As the pressures to make production schedules rise, coating firms look for ways to increase productivity. Obvious answers are speeding up the machine, using overtime or additional shifts or new equipment. Another alternative is to look at the wasted time between coating runs. Many coating lines run more than one product. To switch from one product to another may require more changes than just the web speed, tension and oven temperatures. Other changes might include web width or caliper, web materials, fluids and delivery equipment (pumps, lines and filters), coating head, cleaning idler rolls and associated area cleanups. This paper will cover the steps to consider in establishing a reduction in the changeover time. We will look at planning, data collection, analysis and what to do with this information.
