GS-C480H 80-Inch Double System Double Carriage Full-Function Collar Knitting Machine

·Double System Double Carriage — Dual Guarantee of Efficiency and Flexibility
The defining innovation of the GS-C480H is its double system double carriage with merge-or-separate capability. Driven by one double-system platform, the two carriages can operate in two distinct modes. In merged mode, both carriages work across the full 80-inch knitting bed in coordination, delivering high-efficiency batch production of ultra-wide ribbed collars and broad-format fabrics at a maximum speed of 1.5 m/s — with the multi-action advantage of the double system fully amplified across the ultra-wide carriage travel. In separated mode, the two carriages operate independently in different zones of the needle bed, simultaneously producing two narrower pieces — effectively functioning as two machines in one, dramatically increasing equipment utilization. This flexible switching capability allows factories to adjust production strategy on demand, moving freely between ultra-wide single-piece production and high-volume multi-piece output, maximizing the return on equipment investment.
·80-Inch Ultra-Wide Format — The Widest Coverage in the Full-Function C Series
At 80 inches, the GS-C480H offers the broadest product coverage in the Full-Function C series. This ultra-wide configuration enables efficient production of extra-wide ribbed collars, extra-wide hood neckband ribbing, broad-format multi-color jacquard ribbed fabrics, and all manner of wide-format collar knit materials. In separated mode, the machine transitions into a productive ribbed fabric platform, simultaneously covering both collar production and fabric production within a single equipment investment — creating maximum capacity value and product category coverage for the factory.
·Sinker System — Core Full-Function C Series Quality Feature
As a defining characteristic of the Full-Function C series, the GS-C480H is equipped with a sinker assist system. The sinkers provide effective yarn control and guidance during the knitting process, further optimizing fabric formation, improving surface evenness, fabric uniformity, and structural stability. Under the demanding conditions of 80-inch ultra-wide high-speed production, the sinker assist function is especially critical — effectively reducing fabric quality issues caused by yarn tension fluctuations and ensuring consistent appearance and quality across ultra-wide collar and ribbed fabric products. This is a core quality-assurance feature that distinguishes the Full-Function C series from the economic CE series.
·Multi-Stage Needle Selection Jacquard — Rich Patterns, Full Coverage
The electromagnetic needle selection mechanism, computer-controlled for stable and efficient operation, supports multi-stage needle selection jacquard functionality for automatic production of a wide variety of collar and rib fabric patterns. Supporting flat, tuck, and jacquard knitting functions, the machine delivers strong pattern repeatability and batch-to-batch consistency, covering the full range from plain single-color ribbed structures to complex multi-color jacquard designs — effectively broadening the factory's product portfolio and market reach.
·High-Precision Insert Needle Bed — Full 80-Inch Width Quality Assurance
The machine features a high-precision needle bed with insert needles and notched sinkers, characterized by high hardness, accurate precision, and tight density. Under the high-speed demands of 80-inch double system double carriage operation, this specification ensures consistently flat, uniform fabric surfaces across the full knitting width. Engineered for long-term wear resistance and extended service life, the needle bed maintains stable knitting precision through sustained high-volume production, providing a reliable quality foundation for ultra-wide format products.
·High-Position Leather Roller — Automatic Cast-On Without Fabric Covering
The high-position leather roller system enables fully automatic cast-on without any manual fabric covering, allowing operators to load new products and switch designs at any time with ease. On an 80-inch machine, this feature is especially impactful — manual fabric covering at such a wide format would be exceptionally time-consuming and labor-intensive. By eliminating this step entirely, the GS-C480H significantly reduces changeover preparation time, improves production line responsiveness, and reduces operator workload across every production shift.
·Upper-Lower Composite Traction System — Even Pull Across the Full 80 Inches
The upper-lower combined composite traction system deploys upper and lower traction components in coordination to apply smooth, even tension across the full 80-inch fabric width, preventing edge curl, distortion, or dimensional variation caused by uneven tension in ultra-wide format production. The thickened lower roller provides enhanced traction force, and the specially formulated wear-resistant roller cover ensures long-term durability — collectively guaranteeing flat, dimensionally consistent products throughout double-system high-speed volume production.
·Precision Control & Comprehensive Protection
Stitch density is stepping motor–controlled with 128 (32) selectable levels across a range of 0–650. The take-down roller provides 128 levels of tension control from 0–100. Racking is driven by AC servo motor with a 2-inch range and fine-tuning capability, and the synchronous belt drive with servo motor control ensures smooth, stable operation. The control system features an LCD display with USB input and 256MB memory, supporting Chinese, English, and other languages, with all parameters adjustable in real time during machine operation. The protection system automatically alerts and halts the machine upon detecting yarn breakage, float yarn, rewinding faults, racking failure, needle collision, safety door events, or programming errors. The machine operates on 220V single-phase power with a power-off memory function to protect production data against unexpected interruptions.
