- Fabric Loading: Evenly lay the wet expanded gray fabric on the overfeeding roller. Ensure the fabric enters the oven using the mesh belt, with pieces overlapping head to tail and covered by the mesh belt. Leave a 30 cm gap on both sides of the mesh belt to prevent fabric run-off, contamination, and damage to the mesh belt.
- Speed Adjustment: Adjust vehicle and overfeeding speeds to ensure the fabric is fed into the dryer loosely with an overfeeding amount of about 5%.
- Monitoring: The cloth discharging operator should monitor the drying condition and check for fabric run-off. If any issues arise, sound the alarm and address the problem promptly.
- Mesh Belt Supervision: Regularly check the operating status of the mesh belt, especially the deviation correction device. A failure could cause the mesh belt to deviate, leading to shutdown or damage.
- Post-Operation Shutdown: After completing the work, turn off the heating, overfeeding, fiddling, and cooling systems in sequence. Open the doors on both sides of each oven and run the mesh belt at low speed. Once the temperature drops below 80°C, turn off the moisture exhaust fan and stop the mesh belt operation.
- Regular Maintenance: Clean the filter daily. Weekly, remove lint and dirt from and around the machine’s radiator.
- Fabric Storage: Mark the dried gray fabric and store it in the designated location.
