The Computerised Flat Knitting Jack (5G/7G/9G/12G/14G/16G) is a precision component for computerised flat knitting machines, dedicated to controlling needle movement to weave fabrics of varying thicknesses. It offers multiple gauge options (5G for coarse needles, 16G for fine needles) and is fully compatible with STOLL series flat knitting machines (including models like 7.2/6.2/3.5.2). Widely used in knitting factories producing sweaters, scarves, hats, and industrial knitted fabrics, this jack is made of high-strength alloy steel, ensuring accurate needle control and long-term durability in high-volume production.

Model Name | Computerised Flat Knitting Jack (5G/7G/9G/12G/14G/16G) |
Compatible Machines | Computerised Flat Knitting Machines (STOLL Series: 7.2/6.2/3.5.2) |
Gauge Options | 5G, 7G, 9G, 12G, 14G, 16G |
Material | High-Strength Alloy Steel (Heat-Treated) |
Processing Precision | ±0.005 mm |
Length Options | 88 Series (88.67/88.73/88.87 mm); 114 Series (114.67/114.73/114.87 mm) |
Surface Treatment | Chrome Plating (Anti-Corrosion) |
Application | Sweater, Scarf, Hat, Industrial Knitted Fabric Production |
• Multi-Gauge Versatility: The 5G–16G gauge range covers all common fabric thicknesses—5G for thick wool sweaters, 16G for thin silk scarves—eliminating the need for multiple machine setups and improving production flexibility.
• STOLL Series Compatibility: Tailored to fit STOLL flat knitting machines (a leading brand in the industry), ensuring seamless integration without modifying the machine’s internal structure.
• Ultra-High Precision Control: With a processing precision of ±0.005 mm, the jack ensures uniform needle movement, reducing fabric unevenness from 5% to 0.5% and improving product quality.
• Strong Corrosion Resistance: Chrome plating protects the jack from sweat (in garment production) and workshop humidity, extending its service life by 3 years compared to unplated jacks.
For factories producing both thick winter sweaters (5G) and thin spring sweaters (12G), the ability to switch between 5G and 12G jacks in 30 minutes cuts production line changeover time by 50%, enhancing production efficiency.
Using 16G jacks for thin silk scarves, the ultra-high precision control reduces fabric defects (e.g., loose stitches) by 25%, increasing the product qualification rate to 99% and reducing waste costs.
In factories producing heavy-duty knitted fabrics (e.g., conveyor belts), 5G jacks made of high-strength alloy steel withstand 8 hours/day of continuous operation, reducing maintenance frequency from 2 times a month to once a quarter.
1. What does “G” represent in the model name of the flat knitting jack?
“G” stands for “gauge,” which refers to the number of needles per inch on the flat knitting machine. A higher gauge indicates more needles and thinner fabric—for example, 16G (16 needles/inch) is used for thin fabrics, while 5G (5 needles/inch) is for thick fabrics.
2. Do you provide flat knitting jacks compatible with non-STOLL machines?
Yes, we offer customized jacks for other brands (e.g., Shima Seiki) if you provide your machine’s model and needle specifications. Custom orders typically require a 3-week production lead time.
3. How many flat knitting jacks are needed for a standard flat knitting machine?
The quantity depends on the machine’s width: a standard 1.5-meter flat knitting machine requires 200–300 jacks. We can provide a detailed quantity recommendation based on your machine’s specific parameters.
We offer free samples (1 unit per gauge) for performance testing, with delivery within 5 working days, allowing customers to verify compatibility and quality before bulk purchase.
For bulk orders (500+ units), we provide free online training for your maintenance team, covering jack installation, daily maintenance, and troubleshooting to ensure proper use.
We provide an 18-month warranty for the Computerised Flat Knitting Jack. Any defects caused by materials or manufacturing will be resolved through free replacements, ensuring long-term stable production for customers.
