Manual yarn splicing devices for retrofitting on existing winding installations — delivering 70–90% splice strength for ply and filament yarns.
| Factor | Knot | Splice |
|---|---|---|
| Joint Strength | Weaker — significant strength loss | 70–90% of parent yarn strength |
| Joint Size | Larger, bulky protrusion | Smooth — approx. 1.5× yarn diameter |
| Downstream Processing | Can cause breaks and loom stops | Fewer issues, smoother passage |
| Fabric Appearance | Visible knot defects possible | Cleaner, more uniform finish |
| Splice Length | — | 20–25 mm |
For cotton and blended yarn counts from Ne 100s down to Ne 10s, including cotton open-end yarns. Designed with an automatic pneumatic circuit and Air Tracking System for consistent, operator-independent splice quality.
| Yarn Type | Count Range |
|---|---|
| Cotton / Cotton Blends (Single) | Ne 100s to Ne 10s |
| Cotton / Cotton Blends (Two Ply) | Ne 2/100s to Ne 2/10s |
| Cotton Open End (Single & 2 Ply) | Up to resultant count Ne 5s |
| Synthetic / Acrylic / Wool Blends (Single) | Ne 100s to Ne 10s |
For polyester and viscose filament yarns from 70D to 1500D, including POY and LOY. Features highly finished yarn contact surfaces and special frictioners for clean parallel fiber joining without filament damage.
| Yarn Type | Count Range |
|---|---|
| Polyester / Viscose Filament | 70D to 1500D |
| P.O.Y. and L.O.Y. | Within count range |
Ensures consistent splice quality with every cycle — eliminating operator variation.
Allows positioning at any location along the machine — operators reach any spindle quickly.
Collects and holds yarn tail ends during the splice cycle — keeping the workspace clean.
Smooth, precision-finished surfaces prevent filament snags and yarn damage.
Enables parallel fibers to be joined cleanly without filament damage.
Long-life hardened cutting edges ensure clean, consistent yarn cuts over millions of cycles.
Compatible with ATS, four-wheel trolleys, and rail-mount configurations.
Reduces balloon diameter during high-speed winding — improving package build uniformity.
Retrofit directly on existing cone winding frames — compatible with RJK and other major brands.
Ideal for assembly and doubling winding machines where multi-ply yarn joining is frequent.
Delivers smooth, low-profile splices that pass through traverse guides without snagging.
Especially effective on TFO machines — four-wheel trolley mount provides maximum flexibility.
Used for clean yarn joining on warping machines — reducing beam breaks and improving warp quality.
Air must be free of moisture — install a dryer or moisture trap if needed.
No oil mist in the air supply — prevents contamination of yarn and splice surfaces.
Constant pressure throughout the cycle for reliable splice quality.
Stable pressure supply for consistent filament joining performance.
70–90% of parent yarn strength — far stronger than traditional knotted joins.
No major machine modification needed — fits on existing winding installations.
Separate optimised models for ply yarn and filament yarn — not a one-size-fits-all compromise.
Retrofits on RJK and other major brands of winding, twisting, and warping machines.
Smooth, low-profile splices eliminate knot defects in finished fabric — improving quality grades.
