What factors and variables cause warp from your corrugator?  What corrective actions can you perform to adjust for warp conditions?  AICC's course Warp Fundamentals will take the mystery out of the different types of warp.  Learn how paper or combine board reacts to moisture or tension and how operator adjustments can correct warp.  Understand how Automated Process control systems insure bond windows.  Participant will increase their working knowledge of a corrugator moisture control process while keeping bond integrity intact.

Learning Objectives: 

  • Identify and list variables that impact combine board flatness.
  • Explain how moisture effects combine board and liners.
  • Perform a simple test for Paper Fiber Polar Axis Alignment.
