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.

Precision Welding Can Be Inseparable

 

Both ends of the roller body should be heated to release the size of the inner bored hole. After the spindle heads are put in, the roller body and the spindle heads should be held tightly after natural cooling. When everything is ready, a driving fit interface has been formed between the roller body and the spindle heads by means of preheating, welding or bolting. Special care should be taken when welding, because finished corrugated roller body’s temperature will rise constantly when the roller is running, and the roller body also bears pressure of the steam from the inside of the roller body, which will form the so-called “pressure vessel”. In view of this, the roller body and the spindle heads joint must pass the pressure test. When the welding process finished, the work piece shall be put into the furnace for high temperature tempering to reduce stress.

Strict Test to Keep Improving

Before and after the surface treatment including tungsten carbide plating or hard chrome coating of corrugating rolls, it is needed to check the size, hardness, precision, flute profile, and simulation feeding paper. Special projector is used to check the flute profile and feeding different GSM paper to ensure the performance of corrugating rolls.
