Possible Reasons for Shedding
- Excessive product flex; specify stiffer backing.
- The depth of the cut needs to be more moderate.
- Excessive infeed speed.
- The belt speed is too low.
- Contact roll is too aggressive for application (a smaller groove-to-land ratio is needed).
- Sanding in one area of the belt only. Oscillate the belt if possible, or stagger the workpieces across the width of the belt.
- The contact roll is worn-- Redress roll.
