GS-B480H 80-Inch Double System Blanket Knitting Machine

·80-Inch Wide-Format Knitting Capability
The 80-inch needle bed is the defining specification of the GS-B480H, enabling seamless full-width blanket production that eliminates the seam lines, structural weak points, and aesthetic irregularities associated with multi-panel joining. Operating at this width imposes significantly higher demands on frame rigidity, needle bed levelness, and drive system torque output than standard sweater-width machines. As needle bed length increases, the risk of lateral deflection caused by carriage inertia and vibration grows correspondingly. The GS-B480H addresses these demands through a reinforced frame structure and a drive system specifically configured for wide-format operating conditions, maintaining uniform stitch density across the full 80-inch width at operating speeds and preventing the density variation or dropped stitches that can result from carriage oscillation on long needle beds.
·Double System Architecture and High-Speed Drive
The double system configuration delivers two knitted courses per carriage pass, providing a fundamental productivity advantage over single system machines. The synchronous belt drive system, controlled by an AC servo motor, maintains consistent belt tension and transmission precision across the full 80-inch carriage travel span, preventing the left-right density asymmetry that can result from belt slack or transmission lag on wide machines. The servo motor's speed response characteristics ensure smooth, controlled acceleration and deceleration at the carriage reversal points, reducing the fatigue impact on the needle bed and needles during the high-frequency direction changes inherent in blanket production, thereby extending the service life of wear components and reducing maintenance demands.
·Versatile Pattern Capability for Blanket Products
Blanket knitting places different pattern demands than sweater production, with emphasis on large-area jacquard motifs, geometric structures, textured pile effects, and multi-color designs that must remain visually consistent across the full panel width. The GS-B480H supports jacquard, tuck, miss, and other stitch structures, with computer-controlled electromagnetic needle selection delivering stable, high-efficiency needle actuation across all 80 inches of needle bed. This ensures crisp color block boundaries and clean pattern definition in large-format jacquard designs, from solid-color textured fabrics to intricate multi-color patterns — covering the full product range from everyday utility blankets to premium decorative throws.
·Precise Stitch Density Control
For blanket products, stitch density is directly linked to fabric weight, hand feel, and thermal performance — all critical quality parameters for both retail and export markets. The stitch density system uses stepping motor control with subdivision technology, providing 128 levels of fine adjustment across a broad range that accommodates everything from high-loft faux-fur blanket constructions to lightweight summer throws. This precision ensures consistent fabric weight and thickness within and across production batches, a requirement for export orders subject to weight-based acceptance inspection.
·Multi-Color Yarn Carrier System
Blanket products frequently demand rich color expression — multi-color jacquard patterns, striped designs, and color-block layouts all require smooth, rapid yarn color changes during knitting. The GS-B480H is equipped with multiple yarn carriers distributed on guide rails on both sides of the needle bed, shiftable to any position along the full knitting width. This configuration supports simultaneous loading of multiple yarn colors, enabling uninterrupted production of color-intensive blanket styles and minimizing the downtime associated with yarn carrier changes between color sections.
·Take-Down System Adapted for Wide Heavy Fabric
Blanket panels are substantially heavier per piece than sweater panels, placing greater demands on take-down system pull force and the uniformity of tension distribution across the full fabric width. The GS-B480H's take-down roller system uses programmed stepping motor control with multi-level tension selection, allowing precise calibration to match each blanket's weight, construction thickness, and yarn elasticity. Maintaining uniform take-down tension across 80 inches of fabric width is essential to preventing weft bow and uneven take-up that would compromise the flatness and dimensional consistency of the finished blanket.
·Protection System and Intelligent Control
The protection system provides continuous real-time monitoring for yarn breakage, float yarn, needle breakage, racking return failure, and safety door status, triggering automatic alarm and machine stop upon fault detection to protect needles and fabric from damage. The control system features an LCD display with USB input and high-capacity pattern file storage, with all operating parameters viewable and adjustable in real time during machine operation. The interface supports multiple languages including Chinese and English. The machine operates on single-phase 220V power with a power-off memory function that preserves the current working state through unexpected outages, allowing production to resume from the interruption point upon power restoration — particularly valuable for wide-format blanket panels where restarting from scratch represents a significant material loss.
