Singer S1478 Serger Sewing Machine

Singer S1478 Serger — 2-3-4 thread capability

The Singer S1478 Serger is a 2-3-4 thread overlock machine built for garment construction and finishing. It handles seams, seam finishes, hems and rolled edges on woven and knit fabrics. Differential feed prevents stretching on knits and puckering on lightweight material. Free-arm access simplifies sleeves, cuffs and other tubular areas.

Check power supply and workspace before ordering

Verify that your mains voltage matches the machine’s rating and that you have a stable surface with room for the foot control. Confirm the included #14/90 Singer Overlock needles (#2022) suit your thread and fabric choices. Ensure you can thread the colour-coded guides and adjust tension dials, stitch length, lower knife position and movable upper knife for each project.

Upgrades basic overlockers lacking differential

This model replaces simpler sergers that offer only fixed feed or no rolled-hem settings. The jump is worth it when you need adjustable differential feed for stable knit seams, four fine hemming options, and the ability to disengage the upper knife for non-trimming techniques. Buyers who need cover-stitch or five-thread safety stitches should look elsewhere.
