Heating is very important for high speed. Heat well, Speed faster.
A. Start the corrugating rolls before filling in steam to avoid abnormal deformation.
B. Check the temperature of corrugating roll and pressure roll regularly to avoid temperature decrease caused by accumulation of condensate water.
C. If the temperature is abnormal, please check and keep the correct position of siphon to let condensate water out successfully.
Flute Profile
Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement.
