Double-sided machine - glue excess

This problem is the opposite of the amount of glue that is described in the previous section. As shown, the amount of glue on the paste line is too much, causing glue waste and board warpage. The reason may be that the distance between the metering roller and the paste roller is too large, and the tightness between the top roller and the floating pressure roller causes the corrugated medium to be crushed and mixed with the paste.
