GS-V336 36-Inch Three System Full-Function Shoe Upper Knitting Machine

·Three-System Single Carriage — The High-Efficiency Engine for 3D Shoe Upper Knitting
The GS-V336 adopts a Three System, Single Carriage architecture in which the three-system configuration enables more knitting actions per carriage pass than single and double system machines, delivering significantly higher overall efficiency. The carriage is capable of rapid rotation at a maximum speed of 1.5 m/s, and combined with dynamic density control technology, achieves real-time optimization of knitting speed and stitch density in coordination — meeting the dual demands of 3D flyknit shoe uppers for both knitting precision and production rhythm. The three-system efficiency advantage is fully amplified in shoe upper knitting applications, providing strong production capacity assurance for large-scale flyknit upper orders.
·Patented Innovation: High-Position Take-Up System — Reducing Waste Yarn, Lowering Costs
The most distinctive patented innovation of the GS-V336 is its high-position take-up system. Unlike conventional low-position take-up designs, the high-position system employs an innovatively designed high-position fabric guide path and take-up roller arrangement that effectively reduces waste yarn consumption during the initial cast-on phase of each shoe upper. In large-scale 3D flyknit upper production, the material savings this design generates accumulate significantly with volume, creating measurable raw material cost reductions for the factory. At the same time, it improves cast-on stability, ensuring consistent quality from the very first row through to the completion of each upper piece.
·Multi-Station Sinker System — Enriched Patterns, Superior 3D Fabric Formation
The GS-V336 is equipped with a multi-station sinker system — a key functional module specifically optimized for 3D flyknit shoe upper knitting. Multi-station sinkers provide precise yarn control and support at multiple positions simultaneously during the three-dimensional knitting process, significantly expanding the range of achievable pattern types and satisfying the complex knitting requirements of 3D shoe uppers — including three-dimensional structural zones, elastic regions, ventilation perforations, and surface texture variation. Compared to conventional single-station sinker designs, the multi-station configuration offers a decisive technical advantage in the complex knitting scenarios unique to 3D shoe uppers, and is a core technology enabler for the GS-V336's ability to produce top-tier 3D flyknit upper products with consistent quality.
·Adjustable Tight Tuck Function — Tight-Density Knitting for Enhanced Structural Performance
Another patented innovation of the GS-V336 is its adjustable tight tuck function, which supports tight tuck knitting structures. By precisely controlling the tension of tuck loops, the machine achieves high-density tight knitting in specific zones of the shoe upper, meeting the functional requirements of athletic footwear for localized support strength, shape stability, and a secure fit. This capability enables the GS-V336 to produce seamless density transitions within a single upper piece — from tightly structured support zones to open, breathable mesh areas — with precise control, which is a key process capability for producing high-end functional athletic shoe uppers.
·Dynamic Density Control — Precise Response to Complex 3D Knitting Requirements
The dynamic density control system enables real-time adjustment of stitch length throughout the knitting process, creating density gradients and three-dimensional shaping across different zones of the same upper piece. Combined with three-system efficiency, this achieves precise knitting of complex 3D structures without compromising production speed. Working in concert with the adjustable tight tuck function and multi-station sinker system, dynamic density control enables the GS-V336 to produce premium 3D flyknit shoe uppers that excel in both functional performance and visual appeal.
·Comprehensive Knitting Functions — Optimized for Shoe Upper Production
Supporting tight tuck, transfer, tuck, miss, and jacquard knitting techniques, the machine is systematically optimized for the technical requirements of 3D flyknit shoe upper production. Three gauge options — 12G, 14G, and 18G — cover the mainstream range of athletic shoe upper fabrics from medium-density to fine high-count structures. The standard 36-inch knitting width is complemented by optional configurations of 52 and 72 inches, flexibly accommodating different shoe sizes and production scales.
·16-Carrier Yarn System — Full Support for Multi-Color Flyknit Upper Production
The 16-carrier yarn system — mounted on both sides of 4 guide rails — allows yarn changes at any needle position, providing the operational flexibility required for multi-color jacquard flyknit shoe upper production, supporting the efficient and stable production of color-rich, pattern-complex premium athletic shoe upper products.
·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.
