The apparel line workhorse

Single Needle

Single-needle drop-feed lockstitch — the standard for apparel construction. Direct drive, automatic backtack, thread trim. Modern variants run 5,000+ SPM with stepper-motor control.

The SW-8000A is the flagship: stepper-motor stitching, fully automatic, the kind of machine an apparel contractor runs for ten years and rebuilds twice.
