JUKI MF-7523-C11-B56/X83049 3-Needle 5.6mm Coverseam Collarette Binder Head Industrial Sewing Machine

Flat-Bed, 3-Needle 5.6mm Coverstitch Machine with Collarette Binder

The JUKI MF-7523-C11-B56/X83049 is part of the advanced MF-7500 Series, specifically designed for high-quality coverstitching with a focus on attaching collarettes. This model boasts a range of innovative features aimed at improving seam quality and operational efficiency.

Key Features:

• Superior Seam Quality: Equipped with advanced mechanisms such as a new feed system and differential-feed micro-adjustment, this machine ensures precise and consistent stitching. The looper thread twining prevention system, a standard feature, enhances maintenance ease by preventing thread jams.

• Optimized for Collarette Attaching: The C11 model is tailored for attaching collarettes on underwear, briefs, and knitwear. It includes an electromagnetic tape cutter (TC16), enhancing ease of use and operational efficiency during the sewing process.

• Oil-Free Sewing with Dry-Head Technology: Inherited from the MF-7500 Series, the dry-head technology in the MF-7500D model prevents oil stains on fabrics, minimizing the need for post-sewing stain removal and rework. This feature significantly improves the quality of the finished products.

• Versatile Feed Mechanism: The machine's feed locus can be adjusted both vertically and horizontally, providing excellent adaptability to different sewing materials and requirements. This adjustability ensures optimal performance and seam consistency.

• Adjustable Feed Longitudinal Position: The ability to adjust the feed's longitudinal position helps reduce uneven material feeding and puckering, especially when working with elastic materials. This feature enhances the machine’s capability to handle a variety of fabric types.

• Precise Differential Feed Adjustment: The differential-feed micro-adjustment allows for precise tuning of the feed ratio to match the material being sewn. This ensures a consistent feed even with varying stitch lengths, offering flexibility and control for diverse sewing applications.

• Micro-Lifter Mechanism: The presser foot can be kept slightly raised, which is ideal for sewing delicate or elastic materials. This feature reduces material slippage, warping, and potential damage, ensuring smooth and accurate stitching.

• Enhanced Looper Thread Management: The looper thread twining prevention mechanism trims the looper thread in case of breakage, preventing it from wrapping around the looper thread cam. This system, mounted externally for better accessibility, simplifies maintenance and enhances machine reliability.

• Compatibility with Standard Components: Designed with commonality in mind, the machine supports commercially available components like presser feet, throat plates, and needle clamps, making replacements and adjustments straightforward and cost-effective.

• Efficient Direct-Drive Motor System: Featuring a direct-drive motor, the machine ensures quick startup and precise stopping, improving overall responsiveness and accuracy. The absence of a V-belt reduces maintenance concerns and belt shavings, while also lowering power consumption by 29% compared to traditional models.
