The SPEEDWAY® SW 2290S is a fully electronic zig-zag machine, and the difference from a conventional zig-zag is what it will actually sew. Where a mechanical machine gives you one zig-zag and maybe a three-step, this one carries 16 built-in stitch patterns — straight stitch, standard zig-zag, two-step and three-step zig-zag, four left scallops, four right scallops, and blind stitch in both standard and L-type — all selected from a multifunction color LCD touch screen. Pattern parameters are typed straight into the screen, and an internal zig-zag pattern input function lets the operator build stitch sequences the factory presets do not cover.
Everything else is electronic too: automatic thread trimmer, automatic reverse, automatic presser foot lifter, and automatic needle positioning, driven by an AC servo direct drive motor. It reaches 5,000 rpm and swings up to 10 mm on three-step patterns. The mini-oil lubrication system feeds only the needle bar and hook, so the fabric stays clean — which is the whole point on lingerie, lace, and light-colored garments where an oil mark scraps the piece.

Key Features
- 16 built-in stitch patterns — straight stitch, standard zig-zag, two-step and three-step zig-zag, four left scallops, four right scallops, and blind stitch in standard and L-type, so decorative and functional work run on one machine
- Color LCD touch screen panel — patterns are selected and parameters entered directly on screen, with no mechanical cam changes and no guesswork between operators
- Internal zig-zag pattern input function — build stitch sequences beyond the factory presets when a customer specification calls for it
- Full electronic automation — automatic thread trimmer, automatic reverse, automatic presser foot lifter, and automatic needle positioning
- 10 mm maximum needle swing on three-step patterns and 8 mm on two-step, with a 5 mm maximum stitch length
- AC servo direct drive — no belt loss, immediate response, quieter running, and 5,000 rpm on stitch widths under 4 mm
- Mini-oil lubrication system — oil is delivered only to the needle bar and hook, keeping the fabric clean on light and delicate materials
- Titanium-treated inner hook — the metal coating on the inner hook prevents the heat build-up that shortens hook life on long high-speed runs
- Hook axis compensation structure — compensating the hook axis keeps the phase position of the hook tip consistent, protecting loop pick-up timing
- Newly developed feed mechanism — feed dog height and tilt have a widened adjustment range (upward, horizontal, downward), so the machine handles steps between high and low sections of a garment
- Continuous cyclic sewing — programmed stitch cycles repeat automatically for repetitive operations
- Hidden-type bobbin winder built into the head, and an LED work lamp for stitch visibility
Ideal For
- Lingerie and underwear — elastic attaching, lace joining, and decorative edging
- Women's jackets and blouses — scalloped edges and decorative borders
- Collars and facings on overalls, uniforms, and workwear
- Swimwear and stretch garments needing three-step zig-zag on elastic
- Blind hemming with the standard or L-type blind stitch without changing machines
- Appliqué, monogram borders, and decorative topstitching on light fabrics
- Bridal, formalwear, and children's wear where scalloped finishing is a selling feature
- Shops replacing a cam-driven zig-zag that can only produce one or two stitch shapes
