GUIDE FOR PRODUCT CHANGE WITHOUT STOPPING BOARD-LINE 1312RE T0 1312FR – MK 6

Case Study No. 2
Change on 16/01/2008

Chart below is presenting Dryer temperature profile during this change.


Core Mix phase went smoothly and without any incidents or spillages. Only one board was rejected at the Wet End Transfer (3 m long) to avoid excessive gap in the Dryer.


Aggressive adjustments (particularly to the set points in Zone 2) ensured that extended drying time was compensated for by decisive reduction to drying temperatures. Note that TI9021 probe has never recorded temperature higher than 118 degrees Celsius.


Additional testing of boards was performed at the Dry End and all results were positive.

Complete success.
