Key Features

1. Automatic Edge Alignment The machine automatically aligns the elastic and fabric edges before each sewing cycle begins — eliminating the manual positioning step that requires skilled operators in conventional elastic attaching operations. Every piece is correctly positioned from the start.

2. Automatic Sewing Once aligned, the complete elastic attaching stitch runs automatically from start to finish. The machine maintains consistent stitch quality, tension, and needle pitch across the full 35–60 cm sewing range without operator adjustment during the cycle.

3. Automatic Waist Tightening The SK-1131 automatically applies the correct elastic tension during attachment — producing a consistent, even gather on every finished piece. Eliminates variation in gather tightness that commonly occurs in manual or semi-automatic elastic attaching operations.

4. Uniform Net Bottom Line Stop Edge The stop edge width within the net bottom line is uniform across every piece — producing a clean, consistent elastic attachment that simplifies and improves the quality of subsequent downstream sewing operations.

5. Dual-Track Nose Design with Centered Head The centered machine head and dual-track nose design provide enhanced stability at high speeds, reducing vibration and improving stitch consistency — particularly important when running at the machine’s 5000 RPM maximum speed.

6. 5000 RPM High-Speed Operation Running at up to 5000 RPM with the W3664HP-33A head, the SK-1131 delivers 180–240 pieces per hour — the throughput needed for large-scale women’s underwear production lines.

7. Adjustable Needle Pitch Standard configuration at 5.6 mm needle pitch, with optional configurations of 4.0, 4.8, and 6.4 mm available — allowing the machine to be set up for different fabric weights, elastic types, and stitch appearance requirements across different underwear styles.

8. Stable Sewing Dimensions for Downstream Efficiency Consistent sewing dimensions mean finished pieces dock accurately into subsequent operations — waistband attachment, leg hem finishing, and labelling — without correction, reducing rework and improving overall line efficiency.

9. CE & ROHS Certified Meets European CE and ROHS certification standards — suitable for export-oriented factories supplying global lingerie and underwear brands.

Everything you need to know about SAKGO’s T-shirt and polo shirt
automation machines before making a purchasing decision.

The SK-1131 is purpose-built for women's underwear elastic attaching — the operation of sewing an elastic band onto the waistband or legband of women's underwear garments. It automates the full cycle including edge alignment, sewing, and elastic tightening, replacing the manual skill traditionally required for this operation.

The machine covers a sewing range of 35–60 cm (center fold distance), accommodating the full range of standard women's underwear waistband and legband dimensions from small to large sizes.

The SK-1131 is designed specifically for women's underwear with a sewing range of 35–60 cm and a W3664HP-33A head optimised for lightweight lingerie fabrics. The SK-1018 is designed for men's underwear waistbands with the same sewing range but configured for heavier waistband elastic and boxer-style garments. Both feature automatic edge alignment, sewing, and waist tightening.

The standard configuration uses a 5.6 mm needle pitch. Optional configurations of 4.0, 4.8, and 6.4 mm are available — select based on the elastic type, fabric weight, and stitch appearance required for your specific underwear style.

The machine requires compressed air at greater than 4 Bar with a consumption of 120 L/min. Ensure your factory compressed air supply meets both the pressure and flow rate requirements before installation.

The machine applies a controlled, preset tension to the elastic band as it is fed through the sewing zone. This tension determines the gather tightness of the finished waistband — it is set once for a given style and then applied consistently to every piece automatically, eliminating the variation in gather tightness that occurs when operators manually control elastic tension.
