JUKI MF-7923-U11-B56 3-Needle 5.6mm Cylinder Arm Coverstitch Industrial Sewing Machine

JUKI MF-7923-U11-B56

Cylinder-Bed, 3-Needle 5.6mm Coverstitch Machine for Collarette Attaching

The JUKI MF-7923-U11-B56 is a high-performance, cylinder-bed coverstitch machine designed for professional use in sewing operations, particularly suited for attaching collarettes to garments like T-shirts, sportswear, and knitwear. This machine, part of the MF-7900 Series, is engineered to deliver superior seam quality and enhanced operational efficiency.

Key Features and Benefits:

• Versatile Cylinder-Bed Design: The cylinder-bed configuration of the JUKI MF-7923-U11-B56 makes it ideal for sewing tubular items and difficult-to-reach areas, such as the sleeves and hems of T-shirts. Its compact design facilitates precise control and ease of maneuverability during sewing, enhancing productivity and versatility.

• 3-Needle 5.6mm Top & Bottom Coverstitching: Equipped with a 3-needle, 5.6mm gauge, this machine provides robust and durable coverstitching, making it perfect for a variety of fabric types and thicknesses. It ensures strong, resilient seams that meet the demands of high-quality garment production.

• Advanced Feed Mechanism for Enhanced Seam Quality: The MF-7923-U11-B56 features a newly developed feed system that allows for external adjustment of the feed locus. This capability enhances the machine's responsiveness to different materials, ensuring consistent and high-quality stitching.

• Differential-Feed Micro-Adjustment: This machine includes a differential-feed micro-adjustment mechanism that allows for fine-tuning of the feed ratio to match the specific needs of the fabric being sewn. Whether working with stretchy or rigid materials, this feature ensures smooth and even feeding.

• JUKI's Dry-Head Technology: Built with JUKI’s innovative dry-head technology, the MF-7923-U11-B56 protects garments from oil stains, significantly reducing the need for post-sewing stain removal and rework. This feature maintains the quality and appearance of finished products.

• Micro-Lifter Mechanism for Delicate Materials: The micro-lifter feature allows the presser foot to remain slightly raised, which is particularly useful when sewing delicate or elastic fabrics. This minimizes slippage, distortion, and potential damage to the material, ensuring clean and precise stitches.

• Looper Thread Twining Prevention: Standard on this model, the looper thread twining prevention system automatically trims the looper thread in case of breakage, preventing it from tangling around the looper thread cam. The external mounting of the looper thread cam improves maintenance accessibility and reliability.

• Compatibility with Standard Components: Designed for compatibility with commercially available parts, the machine can utilize readily available components such as presser feet, throat plates, and needle clamps. This makes it easy to find and replace parts, reducing downtime and operational costs.

• Direct-Drive Motor for Efficient Performance: Although this model does not include thread trimming, the direct-drive motor system adopted in JUKI's advanced models offers quick startup, precise stopping, and enhanced responsiveness. The elimination of the V-belt also reduces maintenance issues and power consumption.
