The specific correction method is as follows: 

1, Open the bonding machine preheating, adjust the temperature, speed; 

2, Take a small piece of cloth, put on the bonding lining, first with the iron initial bonding; 

3, Adjust the pressure of the bonding machine, the initial bonding of the sample into the bonding machine; 

4. Make destructive test on the adhesive sample, such as the uneven distribution of adhesive, weak adhesive force, and adjust again until the test reaches the best process parameter state, and record the process parameter; 

5. Test under the same conditions (same sample, same process parameter, same operator) after one month. If the distribution of adhesive is even and the adhesive force is strong, it is proved that the three measuring instruments are normal. 

6. Keep track of your measurements.
