1. It is possible from the entire flow system to the headbox.
2. It is estimated that the main factors are concentration and automatic control system.
3. For MD control problems of equipment, check the MD-related components and DCS control system.
4. Check whether the liquid level and total pressure of the lower headbox are stable.
5. The large changes in equipment slurry concentration and flow changes follow these two paths to find the reasons.
Instructions for stopping the operation of the rewinder:
When the operation switch is turned off, the rewinder stops working and slows down at a fixed deceleration.
1. Automatically stop at the set paper web length or paper roll diameter. When the automatic stop is selected, and the set length or paper roll diameter is reached, the rewinding stops, and the automatic stop can be set to the length or diameter of the rolled or unwinded paper. Further information on the selection and setting of automatic shutdown is given in Section 4.9 "Rewinding Control Procedures".
2. It will stop automatically when it breaks. During operation, when the paper web breaks, the rewinder will automatically stop and decelerate with a fixed acceleration, and the parent roll will decelerate and stop with an emergency stop.
3. Limit the diameter of the paper roll and stop. When the paper roll reaches the limit diameter, the limit paper roll limit automatically stops.
