What is the reason and solution of the thick rubber line after sealing edge

1. Whether the model is selected accurately, such as fast glue used on a slow speed machine, not bonded, and the hot Sol has begun to solidify, resulting in not pressing tight;
2. Check whether the machining accuracy of the plate is not enough, the saw is not good, and the incision is not straight enough;
3. Whether the sealing edge band is deformed or not enough level or arc type;
4. The pressure wheel of the sealing machine is worn, and the pressure is not uniform up and down, and unilateral rubber lines are thick;
5. The pressure of the sealing machine is not enough, it can not be pressed, and the pressure of 3-5 kg/cm2 is required;
6. Apply too much glue, glue overflow.
