System MXⅡ Solving Challenges for Stable Transport in Roll-to-Roll Equipment

Customer Challenges Quality Variation Caused by Unstable Transport in Roll-to-Roll Equipment

Customer Challenges

Roll-to-roll transport equipment continuously transports substrates such as film and paper while performing processes such as printing, coating, and laminating.
This makes the following challenges apparent.

  • sentiment_sad Quality variation such as print misregistration and uneven coating caused by substrate-tension fluctuations
  • sentiment_sad Winding wrinkles and telescoping caused by unstable tension or speed fluctuations
  • sentiment_sad Increased adjustment work when functions are added for product changeovers
  • sentiment_sad Yield improvement stalls because the cause cannot be identified

For large, multi-axis equipment in particular, building a control system that stably transports the substrate at the specified tension and speed is itself a major technical challenge.
