Improvement of productivity

• Reducing the preparation time to change the coating width, high-mix low-volume production is enabled
• The changeable nozzles can digitally set the coating width with its unique nozzle structure. This greatly contributes to improving the productivity and the use efficiency of material

Improvement of use efficiency of material

• When changing the coating width, disassembly and cleaning are not required; besides material loss is reduced
