1. The raw material is sagging.
2. The long-term use of the pressure roller for coating causes the deterioration of the rubber, and the unevenness and the solvent resistance are reduced, resulting in deformation of the rubber roller.
3. Roller pressure balance is poor.
1. Increase the tension (but pay attention to the size change): Use a spreader roller (female roller should be used for aluminum foil).
2. A cooling roller device is provided at the outlet portion of the drying oven.
3. Adjust balance.
