Recently paper machine has been operated at high speed, ex. 1, 000 m/min and more. Paper machine guide device regulates running position of dryer fabrics.
Palm of guide device detects a position of dryer fabrics in contact with running dryer fabrics. Dryer fabrics touch palms strictly, and scrub it, and cause abrasion of dryer fabrics. Palm is sometimes cut off because of this abrasion. Palm break will cause unstable running of the dryer fabrics and make the damage.
Paper machine constructors took the remedy for this kind of trouble, they coated ceramic on the palm surface in order to prevent the abrasion of it.
However there were many edge troubles reported on the dryer fabrics, which were caused by the hardness of ceramic itself and the frictional heat resulting from hard contact with the dryer fabrics.
We carefully studied this reason and completed the remedy as follows.
We improved the resin which harden and protect the edge of dryer fabrics from abrasion.
Weaving of an excellent thread with abrasion resistance prevented dryer fabrics.
We developed new coating material for the palm surface, which prevent from abrasion.
This is reporting the process of our study and the results of our experiment.
