Die Gap Adjustments Key to Symmetric Profiles:

1.Die Gap Controls the Shell Velocity

2.Small Die Gaps associated with High Shell Velocity

3.Shell Velocity must Match Mold Velocity in the Mold Tunnel 

4.Low Shell Velocity Causes Leaning Profile

5.High Shell Velocity Causes Folds or Ripples in the Shell
