Corrugating roll is the most important part of corrugatedcardboard production equipments. Its material is generally made of48CrMoA steel, after the surface heat treatment and cold treatment,the hardness can reach over HRC59.Corrugating roll is also theheart of single facer machines. Corrugating roll is divided intoupper roll and lower roll, its special socket shape making two-rollpaired mesh assembly, the meshing mechanism distinct from the usualgear. Lower corrugating roll for active roll, shaft end fitted withgears, motor reducer driven lower corrugating roll rotation. Uppercorrugating roll for driven roll, rely on roll teeth meshingtransmission .In order for corrugated paper shaped between up rolland lower roll, pressure on its forming, must exert some pressureon the corrugating rolls. The corrugating roll is in addition torotate around its own axis and direction. This movement is throughthe radial pressure cylinder corrugating roll ends, biting pressureof meshing for running.
