Hanging (freezing) wire

1. This usually results when wire does not oscillate in CD over suction boxes.
— some relief is obtained by ensuring properly graduated vacuums over suction boxes.

2. Low vacuum drainage elements may preclude freezing wires.

3. Inadequate wire tension can also contribute to the hanging or freezing of the wire.

— It is essential to maintain proper tension to prevent this issue.

4. Another factor that can cause the wire to hang or freeze is the presence of contaminants or debris on the wire surface.

— Regular cleaning and maintenance of the wire can help prevent this problem.

5. Insufficient water removal from the wire can lead to freezing.

— Proper water removal techniques, such as using foils or vacuum boxes, should be implemented to ensure efficient drainage.

6. In some cases, the use of anti-freeze agents or additives in the paper machine system may be necessary to prevent the wire from freezing.

7. It is crucial to regularly monitor and adjust the temperature and humidity levels in the paper machine environment. Extreme temperature variations or high humidity can contribute to wire freezing.

8. Proper alignment and positioning of the wire on the machine are essential to prevent hanging or freezing. Any misalignment or uneven tension can disrupt the wire’s movement, leading to freezing issues.

9. Regular inspections and maintenance of the machine’s mechanical components, such as rolls, bearings, and guides, are necessary to ensure smooth wire movement and prevent freezing.

10. In severe cases of wire hanging or freezing, it may be necessary to stop the machine and manually remove the frozen sections to prevent further damage.

Overall, preventing wire hanging or freezing requires a combination of proper machine operation, maintenance, and monitoring to ensure optimal performance and avoid production disruptions.
