4-Systems: In a 4-system machine, there are typically 4 yarn feeders (or "systems"), each controlling a separate yarn or group of yarns. These feeders can be configured to use different yarn types (e.g., cotton, wool, polyester) and colors, allowing the production of more complex designs with multiple yarns
Flat Knitting: This type of machine produces flat (rather than tubular) knitted fabric. Flat knitting machines knit fabrics in a bidirectional motion, forming a flat sheet of fabric rather than a tube, which is ideal for making items like sweaters, blankets, and other items where flat shapes are needed.
