The SP-S3 is a high-speed overlock (serger) machine designed for reliable edge-finishing and seaming of light to medium-weight fabrics. Operating at up to 6,500 rpm, the SP-S3 simultaneously trims the fabric edge, finishes the seam with 3 or 4 threads and feeds both layers with a differential feed mechanism — preventing puckering on woven fabrics and stretching on knitwear. The compact, low-profile head keeps the operator's line of sight close to the presser foot, and the lay-in threading system significantly reduces threading time versus conventional overlock machines. Suitable for knitwear, underwear, sportswear and general garment assembly lines.
High-speed operation at up to 6,500 rpm for maximum output on knitwear, underwear and sportswear overlock seaming operations.
Configurable for 3-thread or 4-thread overlock — 3-thread for edge-finishing and light seaming; 4-thread for a more secure seam on medium-weight fabrics.
Adjustable differential feed ratio prevents puckering on woven fabrics and eliminates stretching on knitwear — essential for consistent seam quality across all fabric types.
Integrated upper and lower blade set trims the fabric edge simultaneously with overlock formation — clean, even seam allowance on every pass.
Colour-coded lay-in threading guide eliminates the tedious needle-threading of conventional overlocks — significantly reduces machine downtime when changing thread colours.
Centralised automatic lubrication system ensures consistent oil distribution to all moving parts — extended machine life and reduced maintenance intervals.
