Our Motorized Two Finger Selvedge Uncurler is a critical edge-processing device installed at the infeed of stenter frames and heat-setting machines. It actively unrolls and flattens curled or folded fabric selvages before the fabric enters the pin chain or clip chain, ensuring perfect edge alignment, reducing pin-outs, and preventing fabric defects during drying and heat-setting.
Built with a compact geared motor and precision-machined threaded fingers, this unit delivers consistent, synchronized edge opening at any production speed. The adjustable handle lets operators set finger angle and position quickly, while the durable metal housing withstands the high-temperature, humid environment of textile finishing lines.

Stenter Frame Infeed & Outfeed Systems: Positioned right before the pin chain or cloth clips to eliminate fabric edge curl and prevent un-pinned edge defects.
Knitwear Finishing & Dyeing Lines: Specially designed for single-jersey, rib knit, elastic spandex, and lightweight woven fabrics that naturally roll up at the selvedges.
Slitting & Opening Machines: Ensures precise edge alignment prior to rotary slitting or fabric inspection.
Printing & Coating Machines: Prevents double-folded fabric edges from clogging rotary screens or doctor blades.
Q1: What is a two finger selvedge uncurler used for?
A: It is mounted at the entry of a stenter frame or setting machine to unroll and flatten curled fabric edges (selvages) before the fabric is clipped or pinned onto the chain. This prevents fabric from dropping off the pins, folding over at the edge, or developing crease defects during heat setting.
Q2: Is this unit compatible with my stenter machine brand?
A: The standard mounting bracket fits most common stenter frames including Monforts, Babcock, Artos, Bruckner, LK, Il Sung, and other Chinese/European models.
Q3: What is the difference between 2-finger, 3-finger, and 4-finger uncurler?
A: The number of fingers refers to the number of rotating metal rods that contact the fabric edge. A 2-finger unit suits most standard woven and light-to-medium knitted fabrics. A 3 or 4-finger unit is recommended for heavy, highly curled, or tightly woven fabrics where more contact length is needed to fully flatten the edge.
Q4: Does this come with a motor, or is it a mechanical manual type?
A: This listing is for the motorized version — it includes a geared electric motor that actively drives the fingers. A purely mechanical (passive) type is also available on request; please contact us if you need the non-motorized version.
Q5: How do I install and adjust it on my machine?
A: The unit bolts onto the existing stenter infeed frame using the universal mounting bracket. Once installed, adjust the finger angle and distance from the fabric edge using the red-handled lever. The tapered fingers should gently contact the underside of the curled selvedge and lift it flat as the fabric runs through. Detailed installation instructions are included with every order.
