ELSPREADER Pneumatic Selvedge Uncurler (Model LPA 03)
Manufacturer: Erhardt+Leimer (E+L), Germany
1. Product Overview
ELSPREADER LPA 03 is a premium pneumatic selvedge spreading device engineered by Erhardt+Leimer, a global leader in web guiding and textile processing control systems. It is specially designed to flatten, uncurl and smooth curled, folded or frayed fabric selvedges right before pinning on stenter frames, sanforizing lines, and finishing ranges .
This air-powered spreader delivers gentle yet reliable edge opening performance, making it ideal for ultra-delicate elastic knits, jersey, spandex blends, lightweight woven fabrics and easily curling textiles that cannot withstand harsh mechanical spreading.
2. Core Working Principle
Compressed precision air jets deliver directional airflow to lift and stretch rolled fabric edges evenly:
1. Adjustable air nozzles allow fine-tuning of airflow volume and jet angle for different fabric curl levels
2. Soft air contact eliminates physical abrasion, snags or seam damage common with mechanical finger spreaders
3. Stabilizes selvedge geometry so fabric enters stenter pins perfectly flat for uniform heat-setting and consistent finished width
3. Key Features & Advantages
Premium Build & Adjustability
– Full stainless steel robust housing, corrosion-resistant for humid dyeing & finishing workshop environments
– Dual heavy-duty hand-adjustment knobs for precise vertical pressure and gap calibration
– Mounting shaft for quick, rigid installation on standard stenter side brackets
– Spring-loaded pressure plate accommodates fabric thickness variations and thick seams without marking cloth
Fabric-Friendly Pneumatic Design
– Zero mechanical friction contact with delicate yarns, preventing pilling, tearing or edge distortion
– Single-side or dual-side air jet operation configurable for mild vs severe selvedge curling
– Optimized airflow channel minimizes compressed air consumption for operational cost savings
Production Boost Benefits
– Eliminates pin skip, fabric skew, uneven width and inconsistent shrinkage after stenter processing
– Dramatically reduces downtime caused by mis-pinned curled edges
– Compatible with line speeds up to 200 m/min for high-volume textile finishing lines
– Low maintenance: no wearing contact rollers/fingers, less lint buildup and component wear
4. Wide Application Range
Perfect fit for these textile production lines:
– Stenter / Heat setting frames (most common application)
– Sanforizing, compacting and preshrink finishing machines
– Coating, laminating and printing web processing lines
– Fabric types: Elastic jersey, cotton knits, spandex blends, viscose, silk, thin polyester woven, easily curled single jersey cloth
