The Jack E5-5-03/333 is the new generation of Jack's renowned 5-thread safety stitch overlock — the direct successor to the proven E4S-5-03/333. This dual-function machine combines a 2-thread chainstitch with a 3-thread overlock in a single pass, producing a reinforced seam with simultaneous edge finish — the strongest, most professional construction used in workwear, denim, and structured garment production. Powered by an integrated 550W direct drive servo motor mounted on the main shaft, the E5-5-03/333 delivers consistent operation at speeds up to 5,500 stitches per minute. The convertible feed-dog system adapts effortlessly between A-grade (light), M-grade (medium), and H-grade (heavy) materials, making this machine suitable for everything from knitwear to denim and jeans production. Ideal for workwear, uniforms, denim and jeans, sportswear, knitwear, jackets, structured outerwear, and any application requiring a strong, finished seam in a single operation.
