Juki MF-7900/7900D  Series 

H22, H23 for Hemming (with Left Hand Fabric Trimmer)

This model is ideally suited for hemming processes on sleeves and the bottoms of T-shirts, Polo shirts, and similar garments. It features a left-hand fabric trimmer that ensures fabric is consistently trimmed parallel to the seam. The upper knife stroke can be easily adjusted for precision and convenience.

Innovative Feed Mechanism

  • Versatile Sewing: The new feed mechanism enables a wide range of sewing types. The feed locus can be adjusted externally, both vertically and horizontally, enhancing the machine's responsiveness to various sewing materials.

Micro-Lifter Mechanism

  • Delicate Material Handling: The presser foot can be kept slightly raised, allowing for the sewing of elastic or delicate materials. This feature effectively reduces slippage, warpage, and material damage.

Differential-Feed Micro-Adjustment Mechanism

  • Precision Adjustment: The differential feed amount can be finely adjusted to suit the material being used. The differential feed ratio remains constant, even if the stitch length is changed, ensuring optimal sewing performance.

Enhanced Looper Thread Twining Prevention

  • Standard Feature: An improved looper thread twining prevention mechanism is now standard on the sewing machine. In the event of looper thread breakage, this mechanism activates to trim the looper thread before it twines on the cam, thus preventing any twining issues.
  • Improved Maintainability: The looper thread cam has been relocated outside the sewing machine, enhancing maintainability and ease of access.

Compatibility with Commercially-Available Gauge Components

  • Easy Integration: The machine is compatible with commercially-available components such as the presser foot, throat plate, and needle clamp, allowing for easy replacement and customization without additional modifications.

Direct-Drive Motor System

  • Integrated Efficiency: All sewing machines with a thread trimmer are equipped with a direct-drive motor system. This system ensures swift start-up and precise stop accuracy, improving overall responsiveness.
  • Elimination of Belt Shavings: The direct-drive motor system eliminates the need for a V-belt, thus preventing belt shavings and ensuring cleaner operation.
  • Energy Savings: Direct power transmission from the motor to the sewing machine reduces power consumption by 27% compared to conventional models.

The MF-7900D Series, with its advanced features and innovative mechanisms, offers superior performance, enhanced maintainability, and increased efficiency. This series is designed to meet the demands of modern sewing operations, providing high-quality results with reduced energy consumption and maintenance requirements.
