JUKI MF-7523-U11-B56/X83047 3-Needle Coverseam Flat Bed Industrial Sewing Machine

Flat-Bed, 3-Needle 5.6mm Coverstitch Machine (Universal Type)

The JUKI MF-7500 Series sets a new standard in coverstitch machines, designed to enhance seam quality with advanced features and innovative mechanisms.

Key Features:

• Enhanced Seam Quality: Equipped with advanced sewing mechanisms, including a new feed system and differential-feed micro-adjustment, this machine ensures superior seam quality. It also includes a looper thread twining prevention mechanism for easier maintenance.

• Universal Use: Ideal for hemming sleeves and bottoms of T-shirts, as well as for covering sportswear and knitwear. The front cover design allows operators to work closer to the needle entry, improving efficiency in the covering process.

• Dry-Head Technology: JUKI's dry-head technology prevents oil stains, reducing the need for stain removal or re-sewing and ensuring high-quality finished products.

• Versatile Feed Mechanism: The feed locus can be adjusted both vertically and horizontally, adapting to various sewing materials for optimal performance.

• Adjustable Feed Longitudinal Position: Adjustments to the feed's longitudinal position minimize uneven feeding and puckering, especially on elastic materials, enhancing the machine's adaptability.

• Micro-Adjustment for Differential Feed: Fine-tune the differential feed to suit different materials, maintaining a constant feed ratio even with changes in stitch length.

• Micro-Lifter Mechanism: Allows sewing of elastic or delicate materials with the presser foot slightly raised, reducing material slippage, warpage, and damage.

• Improved Looper Thread Twining Prevention: In case of looper thread breakage, the prevention mechanism activates to trim the thread before it winds around the looper cam, ensuring smooth operation and easier maintenance.

• Compatibility with Commercial Components: Utilizes common components like presser feet, throat plates, and needle clamps, making replacements and adjustments convenient and cost-effective.

• Direct-Drive Motor System: All models with a thread trimmer feature a direct-drive motor, enhancing startup speed, stop accuracy, and overall responsiveness. This design eliminates the need for a V-belt, reducing belt shavings and lowering power consumption by 29% compared to conventional models.
