Double-sided machine - high or low speed

Double-sided machine - high or low speed is the same as the result of high or low speed on a single-sided machine. As can be seen in the figure below, the paste line on the corrugated line is glued on one side of the other. More side volume. This results in different paperboard bonding qualities, good adhesion of the machine direction paper to the core paper, and formation of a zippered bonded paperboard in the other direction. In the final analysis, the linear velocity of the surface of the top roller and the surface of the web is inconsistent.
If the speed is higher than the speed ratio provided by the equipment manufacturer, the speed of the top roller is too fast or the speed of the paper web is too slow, and the front edge of the corrugation will be too heavy. If the speed ratio is too low, the opposite situation will make The corrugated back edge was excessively glued.
