E+L ELSPREADER Pneumatic Selvedge Uncurler LPA 03
Air-powered selvedge spreader that opens curled edges just before pinning, without touching the cloth hard.
Product Overview
The ELSPREADER LPA 03 is a pneumatic selvedge spreading device from Erhardt+Leimer of Germany. It flattens, uncurls and smooths curled, folded or frayed fabric selvedges immediately before pinning on stenter frames, sanforizing lines and finishing ranges.
Because the spreading action is air-powered rather than mechanical, it opens edges gently. That is what makes it the choice for ultra-delicate elastic knits, jersey, spandex blends and lightweight wovens that curl the moment tension drops.
Key Benefits
- Opens rolled and folded edges without a hard contact face pressing on the cloth
- Suits elastic knits and spandex blends that mechanical uncurlers tend to mark
- Works at the infeed of stenter frames, sanforizers and general finishing ranges
- Stainless steel construction in the wetted section stands up to finishing chemistry
Who It Is For
- Knit finishers running elastane blends who cannot accept edge marking
- Mills upgrading from finger-type mechanical uncurlers after repeated edge complaints
- Plants running a mixed schedule of woven and knitted qualities on one frame
Problems It Solves
- Tube-rolled knit selvedges that get pinned folded and show as a hard line after heat setting
- Edge abrasion caused by a mechanical uncurler bearing on a delicate fabric
- Speed being held back at the infeed because the edge cannot be opened reliably
Application Scenarios
- Jersey and single-knit lines where the selvedge rolls into a tight tube after the dye house
- Spandex blend production where edge tension has to stay near zero
- Sanforizing lines that need the edge presented flat to the compacting section
- Lightweight woven finishing where a mechanical finger would leave a track
Technical Features
- Pneumatic, contactless spreading action rather than a mechanical finger
- Manufactured by Erhardt+Leimer, Germany
- Stainless steel in the fabric-facing section
- Designed to sit immediately upstream of the pinning or clipping point

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
A mechanical uncurler bears physically on the edge and is cheaper to run, but it is not the right answer for elastane and fine jersey. The pneumatic LPA 03 opens the edge with air, so there is no rubbing face. On heavy denim or canvas, a roller or finger type usually does the job at lower cost.
Use Guide
Install directly before the pinning point so the opened edge has no chance to roll again
Feed clean dry air and set pressure from low upward while watching the edge
Check that the nozzle line is parallel to the fabric edge, not angled into it
Clean nozzles on the same schedule as the rest of the infeed to stop finish build-up
Re-check settings after a fabric changeover rather than leaving the previous setting
FAQ
Questions About E+L ELSPREADER Pneumatic Selvedge Uncurler LPA 03
Is this an original Erhardt+Leimer unit?
Yes, the ELSPREADER LPA 03 is an Erhardt+Leimer product made in Germany. We supply it alongside the Chinese-made wear parts we manufacture ourselves, so a mill can order both in one shipment.
Will it handle spandex blends?
That is the case it is built for. The spreading is done by air, so there is no contact face rubbing the elastane edge.
Can I use it on a sanforizer as well as a stenter?
Yes. It is used on stenter frames, sanforizing lines and finishing ranges, wherever a curled edge has to be opened before the next station takes hold.
What air quality is needed?
Clean dry compressed air. Oil or moisture carried into the nozzles will end up on the fabric edge, so treat the supply the same way you would for any air-on-cloth device.
What is the minimum order?
There is no fixed minimum on this item. Single units are normal for a maintenance replacement.
Do you also make the pin plates it feeds into?
Yes. Pin plates, pin plate holders, chains and clips for Monforts, Bruckner, Artos, LK, IL SUNG and KRANTZ frames are our own production.
