PURPOSE
It adheres to the packs through which it exerts pressure on the sanding belt
It is glued to the slipper on the contact grinders
ADVANTAGES
The graphite coating allows for greater sliding, thus reducing the friction and heating of the sanding belt
Longer life of the sanding belt
Better antistatic properties of sandpaper
Reduced heating of the workpiece
Stainless steel is less likely to change color
REMARK
It is bonded to the substrate using a flexible, heat-resistant adhesive
It is often glued to a technical felt of 5 or 10mm thickness
