Unique construction offers savings and
performance advantages over conventional rolls
Produced with synthetic non-woven fabric discs compacted together with a very flexible adhesive that provide the following product advantages:
Self healing: Longer operating duration without routine maintenance
Fluid Control: Removing or applying processing fluids
Friction: Resists slipping on the strip’s surface which equates to control, reduced costs, and higher quality
Non-Marking: “Void Volume” absorbs oxides that mark, and friction capability combined with soft fibre and resin prevent scratches.
Fluid Control System:
Porous roll absorbs solution to relieve hydraulic pressure while maintaining tight contact with the metallic strip.
Roll is compressed to near zero at the nip center creating a seal which is restored with each revolution of the roll.
The porous surface reopens as compression decreases. The sponge-like action removes residual liquid from the strip.
When the roll is compressed again after one revolution in the contact zone, the absorbed solution in the third step is returned to the strip in the wringing zone.
Friction Coefficient:
Due to the unique 3M material characteristics, in dry conditions 3M materials shows better friction coefficient performances than rubber rolls. This difference increases dramatically with the presence of water solutions or an oil medium. The porosity surface of 3M Mill rolls allow perfect adherence to the surface.
Water Wringing: Rubber Vs. :
Under the same working conditions, the 3M Mill Rolls have shown better initial wringing performances.
In case of damage, the 3M Mill Roll self-heals and tends to recover the initial wringing performances while the rubber rolls become more damaged.
Longer Life and Self Healing Characteristics:
3M Mill Rolls with their void Volume and non-woven porosity are slightly compressible. Under pressure, the roll increases in density at the nip. As the density increases, the material compresses inwardly, causing the roll to resist cuts and gouges. This compressive stress allows cuts to heal themselves as the compressing forces push the sides of the cut closed.
Easy to Repair and Reuse:
They are the only ones that can be repaired in the case of an accident.
