GS-V372 72-Inch Three System Full-Function Shoe Upper Knitting Machine

·Three-System Single Carriage — The Efficiency Leader at 72-Inch Ultra-Wide Format
The GS-V372 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. At 72-inch ultra-wide format, the three-system efficiency advantage is maximally amplified — each carriage pass covers the greatest width in the V series, and the time value of the three-system's additional actions per pass reaches its peak expression at this scale. The result is the highest shoe upper output per unit of time in the series, providing the strongest production capacity assurance for factories handling ultra-large-volume flyknit upper orders.
·72-Inch Ultra-Wide Format — Maximum Width in the Full-Function V Series
At 72 inches, the GS-V372 is the widest model in the Full-Function V series and a benchmark ultra-wide configuration in the shoe upper knitting machine category. The capacity advantage this width delivers is exceptional: compared to a 36-inch machine, the 72-inch format nearly doubles output capacity from the same number of machine units; compared to the 52-inch model, the improvement remains substantial. The ultra-wide format also enables production of extra-large-size athletic shoe uppers, wide-format sports protective gear, sports goods knit materials, and all manner of functional knitted products that require greater width — breaking through the product specification limits of standard-width machines and providing ample room for factories to expand their product portfolio.
·High-Position Take-Up System — Maximum Waste Yarn Savings at Ultra-Wide Scale
The GS-V372 features the high-position take-up system patented innovation that effectively reduces waste yarn consumption during the initial cast-on phase of each shoe upper piece. At 72-inch ultra-wide scale, the material-saving benefit of this system is more significant than on narrower machines — the waste yarn savings per piece, multiplied by the ultra-high production volume, generate substantial cumulative raw material cost reductions over an annual production cycle, delivering a compelling return on investment.
·Sinker System with Stepping Motor Control — Full 72-Inch Width Quality Uniformity
The machine is equipped with a stepping motor–controlled sinker system capable of arbitrary precision adjustment for different fabric characteristics and various shaping and stopping effects. At 72-inch ultra-wide format, the stepping motor–controlled sinkers provide uniform, stable auxiliary yarn control across the full knitting width — effectively preventing quality variation across the fabric caused by uneven sinker action in ultra-wide high-speed knitting. Ensuring consistent fabric quality from edge to edge across the full 72-inch span is the core quality control challenge of ultra-wide shoe upper machines, and the GS-V372 delivers the optimal answer through precision stepping motor–controlled sinker technology.
·Adjustable Tight Tuck Function — Precise Tight-Density Control at Ultra-Wide Scale
The machine supports the adjustable tight tuck function, enabling precise control of tuck loop tension to achieve high-density tight knitting structures in specific zones of the shoe upper. At 72-inch ultra-wide format, this function simultaneously applies consistent tight-density control to the corresponding zones of multiple shoe uppers being produced in parallel, ensuring batch-consistent density across support zones, wrap zones, and other key functional areas — meeting the strict product specification uniformity requirements of large-scale production.
·Comprehensive Knitting Functions — Full-Function V Series Capability at Ultra-Wide Scale
Supporting transfer, tuck, miss, jacquard, intarsia, hide shaping, and apparent shaping, the GS-V372 maintains the complete knitting function coverage of the Full-Function V series at 72-inch ultra-wide format. Hide and apparent shaping support enables the production of premium flyknit shoe uppers with precisely formed edge structures, significantly reducing downstream processing steps, improving upper yield rates, and elevating product added value — delivering high-end product quality at ultra-wide production scale.
·1GB High-Capacity Control System — Intelligent Core for Ultra-Wide Multi-Style Management
The GS-V372 is equipped with a 1GB high-capacity memory control system — four times the standard 256MB — capable of simultaneously storing a large library of complex 3D shoe upper pattern files. In 72-inch ultra-wide, multi-style production environments, the 1GB memory advantage is especially pronounced: factories can pre-store the complete pattern data for multiple shoe upper styles simultaneously, enabling rapid changeover without repeated file import/export operations, significantly improving multi-style flexible production responsiveness and management efficiency. The control system features an LCD display with USB input, supporting Chinese, English, and other languages, with all parameters adjustable in real time during operation.
·Yarn Carrier System & Precision Drive
The 2×8 yarn carrier configuration — 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 across the full 72-inch knitting width. The synchronous belt drive with AC servo motor control ensures smooth, responsive operation. The racking system is driven by AC servo motor with a 2-inch range and fine-tuning capability. Stitch density is stepping motor–controlled with 32 selectable levels across a range of 0–650, and the take-down roller provides 32 levels of tension control from 0–100.
·Protection System & Power
The protection system automatically triggers alarms upon detecting yarn breakage, knotting, float yarn, rewinding faults, end-of-knitting signals, racking failure, needle breakage, or programming errors — comprehensively protecting both machine and operator. The machine operates on 220V single-phase power with a power-off memory function to safeguard production data against unexpected interruptions.
