Step 8: Press the cardboard


The corrugated paper core is pressed, and the paper is pulled out from the large roll by the machine and entered into a set of corrugated rollers with high temperature and high humidity and gear. Under the pressure of two gear rollers, the paper forms a corrugated shape with convex and convex phases, so that the corrugated board has strength and buffering ability.

The molded corrugated core will touch another roller with glue, which will glue the corrugated core side, and stick to the roll of paper drawn from the other roller during the rotation process.
