ROSSO-7F Automatic Computerized Cotton Socks Knitting Machine, model RC-7F-1 (ROSSO-7F series).
Cylinder diameter: 3.75 inches. Site/footprint: 150 × 100 × 220 cm. Gross weight: 380 kg.
Applicable needle counts range from 84N to 200N for both plain and terry knitting.
Maximum speed for plain knitting is up to 320 RPM; for terry knitting up to 300 RPM.
Rated supply voltage is 380 V. Ensure your site electrical supply and grounding meet local codes and the machine’s installer requirements.
It can produce plain, terry, jacquard, tuck, mesh, double rib and related fabrics. Common products include multi-color embossed-effect jacquard socks, stereo-effect socks, cartoon socks, elastic slim stockings, business socks and casual socks.
The machine can knit 1 main color plus up to 6 vice (secondary) colors simultaneously. It is equipped with 9 main shuttles and 17 vice shuttles.
The ROSSO-7F has high adaptability for terry materials with technology that improves dimensional control and delivers high flatness on the sock surface, reducing irregularities typical of terry knitting.
Heel rubber can be connected flexibly without a fixed location for tuck or patterning, so there is no strict scope limitation for placing rubber or pattern elements in the heel area.
The 6c cam allows selective control and reinforcement during knitting. It enables optional reinforcement without re-feeding yarn, improving efficiency and flexibility in stitch control and patterning.
No — the machine is designed so fewer parts need to be changed to produce invisible/seamless socks, simplifying changeover and reducing setup time.
Yes — heel knitting can be controlled continuously. This means the machine can form heels without stopping the knitting cycle or being constrained by mechanical limits, improving throughput and consistency.
Yes, the machine is computerized to support jacquard and multi-color patterning. Specifics about control software, supported file formats or user interface vary by supplier — contact the vendor for details and pattern import options.
Routine maintenance (lubrication, needle inspection, tension checks) is recommended. The machine design reduces part changes for some styles, but consumables and wear parts (needles, cams, shuttles) will be required. Most suppliers offer spare parts packages and operator training — confirm availability and terms with your vendor.
Output depends on factors such as sock size, stitch density, pattern complexity, yarn type and changeovers. Because the ROSSO-7F can run up to 320 RPM (plain) / 300 RPM (terry), contact the supplier with your target design/yarn for a tailored production estimate or request sample-run data.
