Copley Rope Savers™
Copley Rope Savers for dryer rope grooves
Short answer: Copley Rope Savers™ are heat shrinkable Fluoro-Flex fluoropolymer liners that we shrink into the rope groove of a dryer. They restore the groove to the right diameter, smooth out chatter and roughness, and stop coating from building up. Each one takes about an hour to install, right on the machine.

Four rope problems it fixes
Threading breaks
A groove that’s worn too deep runs the rope slower than the dryer surface. You get sheet breaks while threading and slack buildup. The liner builds the groove back up.
Coating splash
After a size press or coater, coating splashes into the nearest grooves and wears the ropes. The fluoropolymer surface releases it.
Rough grooves
Chatter marks and roughness chew through ropes. The liner gives the rope a smooth track.
Mismatched diameters
Grooves of different diameters make ropes slip, wear fast and break tails. Rope Savers bring every groove to the same size.
Quick install, on the machine
- Seam the heat shrinkable liner around the dryer journal.
- Fit it into the rope groove.
- Apply heat to shrink it tight into the groove.
That’s about an hour per groove, so it fits into a scheduled shutdown or wash-up. No pulling the dryer and no machining.
Covering the dryer face too?
Rope Savers pair well with an OMS FEP dryer cover on the same can, so the face and the groove both release.
Common questions
What is a Copley Rope Saver?
A heat shrinkable Fluoro-Flex fluoropolymer liner that’s shrunk into a dryer’s rope groove. It brings the groove back to the right diameter and gives it a smooth, non-stick surface.
How long does it take to install?
About one hour per rope groove, during a scheduled shutdown or wash-up.
Why do rope groove diameters matter?
All the grooves need to match. If one is deeper, the rope runs at a different speed from the dryer surface. That slips and wears the rope, and causes tail breaks and slack during threading.
Does it help with coating buildup?
Yes. After a size press or coater, coating splashes onto the nearest rope grooves and sheaves. The fluoropolymer liner releases it, so it doesn’t build up and chew up the rope.
Do I have to pull the dryer?
No. The liner is seamed around the dryer journal and fitted into the groove on the machine.
Ropes wearing out or threading badly?
