Dry marks on double-sided paper at the hottest gui

Dry marks on the double-sided paper at the guide claw
the paste shape of the double-sided paper web has traces of non bonding with the imagined shape of the guide claw in the longitudinal direction of corrugation
reason
the tension on the core paper is too large, so that the core paper falls into the groove of the upper corrugating roller, thus leaving a groove on the core paper on one side of the double-sided paper. When the core paper passes through the paper delivery roller on the double-sided machine, These concave cantilever impact testing machines measure the impact resistance of the material when it is impacted by the pendulum
it cannot stick to the paste
there is dirt on the corrugating roller
the core paper is too wet
due to wear by the guide claw, the temperature gradient on the corrugating roller is ≤ 5 ℃); 6) The groove of the shell surface temperature ≤ room temperature + 50 ℃ is widened
too much vacuum or pressure makes the core paper wrinkle, and the core paper on one side of the double-sided machine cannot stick to the paste on both sides of the fold
measures
reduce the active investment of the company on this next day, reduce the amount of steam injection, loosen the brake device on the core paper
remove the dirt on the corrugating roller
cut off the steam flow to the core paper, Increase the wrap angle on the preprocessor
replace the corrugated roller
reduce vacuum or pressure
