The Jack JK-58450B-003/005 is a modern series of high-speed, double-needle lockstitch machines designed for professional sewing environments. Engineered with a double transport system (tooth-needle), these machines ensure precise fabric feeding, smooth stitching, and consistent seam quality across a wide range of materials, from medium-weight fabrics to heavier textiles.
Key Features:
Double Transport System: Combines needle and feed dog movement to achieve flawless material handling. This system eliminates stitch misalignment and puckering, even at high sewing speeds, ensuring professional-quality results for garments, upholstery, and industrial textiles.
Versatile Versions: Available in standard or fully automatic versions, with optional needle on/off control. Depending on the subclass, the machine can be equipped with standard or enlarged hooks to match the type and thickness of the material being sewn.
Closed Lubrication System: The machine features a sealed oil container rather than a traditional open oil sump. This reduces oil consumption, guarantees optimal lubrication of internal mechanisms, and prevents staining of sensitive fabrics during sewing operations.
Energy-Saving Motor (Automatic Versions): Fully automatic models are equipped with a Direct Drive servo motor that consumes less energy, operates quietly, and integrates a clear, readable control panel directly in the machine head for ease of use and workflow management.
Integrated LED Lighting: The work area is illuminated by a built-in LED system with three adjustable levels of brightness. This ensures optimal visibility of the sewing zone, reduces eye strain during long production shifts, and improves accuracy in stitching detailed or complex patterns.
High-Speed Sewing Performance: With a maximum speed of 3,000 rpm, the machine delivers rapid production capability while maintaining stitch precision.
Presser Foot Adjustment: The presser foot lift ranges from 7 mm to 13 mm, allowing the machine to handle various fabric thicknesses efficiently.
Needle & Stitch Configuration: Equipped with a DPx5 needle system and a needle gauge of 6.4 mm, the machine is designed for consistent, high-quality lockstitch sewing with minimal maintenance.
Applications:
The Jack JK-58450B-003/005 is suitable for industrial and commercial sewing operations including garments, home textiles, upholstery, bags, and heavier materials that require precision stitching. Its reliability, energy efficiency, and advanced lubrication system make it ideal for extended, high-volume production environments.
