The paper laminator glue produced by the board glue line is not uniform

After the paper and corrugated cardboard are mounted on the press, the glue line on the paper is not uniform, I believe that many laminating machine teachers have encountered this problem, then what is the cause of this problem, how can the glue line be uniform and the cardboard bond is still firm?

The reasons for the uneven glue line of the cardboard made by the glue machine are as follows:

1, corrugated cardboard high and low

2. Uneven rubber roller

3, the glue is too thick, poor fluidity

4. There are impurities on the stick

There are several ways to improve the uneven glue thread:

1. Choose corrugated cardboard with high flatness. The uneven level of corrugated cardboard will make the contact area of the cardboard surface uneven, thus affecting the uniform coating of glue.

2, the rubber roll in the use of paper into the machine, many times will cause the rubber roll deformation and bending - solution: need to remove the rubber roll to grind it or replace the new rubber roll

3, adjust the flow of glue, in the case of ensuring adhesion, the glue is thin, and the fluidity of glue is better.

4, do the daily cleaning of laminating machine and rubber roller
