PEEK Roller Set For Multi Finger Selvedge Uncurlers
Matched PEEK roller set for two, three and four finger uncurler banks.
Product Overview
This is the matched-set version of our PEEK uncurler roller, supplied as a bank rather than as a single piece. Roller-type uncurlers use two-finger, three-finger and four-finger designs for different fabric weights and line speeds, and each finger carries its own roller.
Replacing the whole bank at once keeps every roller at the same diameter. That is what stops the edge being opened unevenly when one new roller sits alongside three worn ones.
Key Benefits
- Every roller in the bank shares the same diameter and surface condition
- Matched sets for two, three and four finger uncurler designs
- Self-lubricating PEEK, no grease needed at the cloth line
- One order covers a complete station instead of a piecemeal repair
Who It Is For
- Maintenance planners replacing wear parts on a schedule rather than on failure
- Mills running multiple frames that want one roller specification across all of them
- Engineers who have traced an edge fault to mismatched roller diameters
Problems It Solves
- One new roller running against worn neighbours and opening the edge unevenly
- Repeated short stops as rollers are replaced one at a time
- Edge damage during high-speed operation from a roller that no longer turns freely
Application Scenarios
- Scheduled overhaul of an uncurler bank during a planned shutdown
- High-speed lines where uneven roller diameters show up as edge waver
- Mills standardising roller sizes across several uncurler positions
Technical Features
- PEEK rollers supplied as a matched bank
- Configurations for two-finger, three-finger and four-finger designs
- Black, white and brown PEEK
- Suited to stenters, pre-shrinking machines and printing machines

- Concentricity checked on each piece
- Set packed and labelled together so it is not split in the store
Customisation Options

- Diameters turned from your worn samples
- Mixed sets supplied where inner and outer positions use different sizes
Certifications. We make no certification claim for this part. The original company statement is that products comply with international quality standards; no certificate is named and none is asserted here. Ask us directly if your procurement process requires documentation.
Comparison With Other Options
The single roller is the right buy for an unplanned failure. The matched set is the right buy for planned maintenance, because it removes diameter mismatch across the bank, which is the fault mode that is hardest to diagnose from the finished cloth.
Use Guide
Record which position each old roller came from before stripping the bank
Check every shaft and bearing seat while the bank is empty
Fit the set in one operation rather than across several stops
Spin each roller by hand before running the line
Log the fitting date so the next overhaul can be planned on hours, not on failure
FAQ
Questions About PEEK Roller Set For Multi Finger Selvedge Uncurlers
Why buy a set instead of single rollers?
Because a new roller running next to worn ones opens the edge unevenly. A matched set removes the diameter mismatch that causes it.
How many rollers are in a set?
It follows your uncurler design: two-finger, three-finger and four-finger banks all exist. Tell us the finger count and we build the set.
Can I mix diameters within one set?
Yes, where the inner and outer positions genuinely use different sizes. Send the worn parts and we reproduce the arrangement.
Which machines does this suit?
Stenters, pre-shrinking machines and printing machines that use roller-type selvedge uncurlers.
Is PEEK necessary, or will nylon do?
Nylon is cheaper and works on cooler lines. PEEK handles high temperature and is self-lubricating, which is why it is the standard choice inside stenter conditions.
Lead time for a full set?
Standard sizes within 7 days. Sets turned from your samples are confirmed after we receive them.

Guides That Cover This Part
What Is a Stenter Machine and How Does It Work
The stenter heat-sets and dries fabric by stretching it to width and holding it there under controlled heat.
Key Parts of a Stenter Machine
Entry section, clip or pin chains, rails, heating chambers, exhaust, blowers, temperature control, width adjustment and weft straightener.
Pin Stenter or Clip Stenter Which To Use
Clips leave no pin marks and suit thicker fabrics; pins hold more tension and run faster, to 100 m per minute.
Send A Sample And We Will Match The Profile
Seat profiles and geometry changed across frame generations, so the part itself is more reliable than a model number. We identify it and quote the matching specification.
