JUKI MF-3620-L200-B60B Industrial Direct Drive Industrial Sewing Machine

Juki MF-3620-L200-B60B Direct-Drive Flatseamer

The Juki MF-3620-L200-B60B is a state-of-the-art 4-needle, feed-off-the-arm flatseamer designed for top and bottom coverstitching, offering a stitch width of 6.0mm. Engineered for efficiency and precision, this direct-drive machine is perfect for creating smooth, durable seams on a variety of fabrics including underwear, fleece wear, swimsuits, and modern stretch materials.

Key Features:

Advanced Seam Quality: The Juki MF-3620-L200-B60B comes equipped with innovative mechanisms that ensure consistent, high-quality seams. Its feed mechanism and differential-feed micro-adjustment allow for precise control, making it ideal for both light and heavy materials.

Enhanced Safety and User-Friendliness: This model is designed for ease of use and operator safety. The front cover is trimmed, bringing the operator's hands closer to the needle entry area, which enhances work efficiency. It also features a safety cover over the bobbin thread cam section to prevent accidental injury.

Oil-Free Operation: Juki’s dry-head technology prevents oil leakage, eliminating the need for stain removal and reducing maintenance efforts. The machine’s unique frame shields and micro-quantity lubrication system keep the sewing area clean, preserving fabric integrity and boosting productivity.

Direct-Drive Efficiency: The Juki MF-3620-L200-B60B is equipped with a direct-drive servomotor, which reduces power consumption by approximately 52% compared to traditional models. This motor offers exceptional responsiveness, allowing for precise control even on curved seams and complex stitching patterns.

Versatile Presser Foot Design: The L200 model features a both-side trim presser foot and lap former, which trims the edges of the material as it sews, creating a clean, professional finish with no exposed edges. This function is particularly useful for joining and hemming processes in garments such as sportswear, lingerie, and knitwear.

Innovative Micro-Lifter Mechanism: Elastic or delicate materials can be sewn with the presser foot slightly raised, reducing the risk of slippage or damage throughout the sewing process. This ensures that even the most sensitive fabrics are handled with care, maintaining their quality and appearance.

Improved Material Handling: The unique presser foot design includes a cloth-cutting mechanism that allows for smoother feeding of materials, reducing the risk of damage and prolonging the life of the cutting knife. The differential feed ratio can be easily adjusted to match the material characteristics, ensuring optimal performance for every project.
