How to adjust the dissatisfaction on the back glue before martini tied the dragon?

Adjust the thickness of rubber wheel and rubber layer.

If the martini glue dragon is not satisfied before and after, the thickness of rubber wheel and rubber layer should be adjusted. Set the temperature according to the glue brand, and strictly control the glue temperature within the parameters provided by the manufacturer. The thickness of the adhesive is generally controlled between 0.6 and 2mm. Martini is bound with glue, and the glue layer should be uniform. The adhesive is too thin, which affects the adhesive strength. Thick glue increases the cost. The length of adhesive backing should be slightly shorter than the cover size 1-2mm. Too long time is likely to cause residual glue to stick to the mechanical transmission parts, leading to failure. Too short will cause the back and feet of the book to be empty and affect the quality of the book.
