Juki MEB-3900J01AA1, Computer-controlled Eyelet Buttonholing Sewing Machine

Juki MEB-3900 Series 

Enhanced Productivity

• High-Speed Operation: The MEB-3900 operates at a maximum sewing speed of 2,500 stitches per minute, significantly reducing machine time.
• Speedy Cloth Cutting Knife: The air-driven cloth cutting knife offers excellent responsiveness, operating faster than conventional knives.
• Direct-Drive Main Shaft: The adoption of a compact AC servomotor directly connected to the main shaft enhances responsiveness, reduces noise and vibration, and eliminates the need for a V-belt, thereby reducing power consumption.

Reliable Thread-Trimming Mechanism

• Versatile Thread Trimmers: Two different thread trimmers are available, ensuring thread trimming without fail and in a short time. This design eliminates the need for fine adjustments when changing the sewing length.

Electronic Control and Digital Management

• Active Tension Mechanism: Electronically controlled needle thread tensions can be set digitally on the operation panel and registered on a pattern-by-pattern basis, ensuring consistent sewing conditions and high-quality seams.
• Separate Tension Settings: Different thread tensions can be set for various sections of a buttonhole, including eyelet and parallel sections, ensuring high-quality seams and preventing thread slip-off or raveling.

Ease of Use and Operator Convenience

• Simplified Threading: The machine requires fewer parts to be threaded, making threading quicker and easier.
• Voice Guidance System: Provides production support by giving the operator information about the number of pieces produced, work progress management, and the operation rate of the sewing machine.

IoT Integration for Data Management

• Data Management via IoT: Sewing machine adjustments data can be transferred to an Android tablet in contactless mode, enabling quick checks for uniform settings and confirmation of sewing machine conditions in a sewing line.
• USB Port for Data Transfer: Data management and software updates can be easily carried out using a USB thumb drive.

Improved Operator Experience

• Enhanced Viewability: The design of the machine head and the placement of the cloth cutting knife improve viewability and workability.
• Adjustable Cloth Cutting Knife: The height of the spacer can be adjusted when the blade of the cloth cutting knife wears.
• LED Light: An LED light is provided as standard, with adjustable brightness to improve workability around the needle entry area.

Maintainability

• Latch Type Bottom Cover: Allows for easy daily maintenance without raising the machine head.
• Gas-Spring Supported Machine Head: The machine head is supported by a gas-spring for easy raising, facilitating smoother cleaning and threading. The tilted-up machine head can safely be taken down thanks to the mechanical lock.

Working Environment Improvements

• Reduced Vibration and Noise: The direct-driven main shaft and redesigned thread take-up cam and looper cam reduce vibration and noise.
• Clean Working Environment: The machine automatically reclaims cloth chips after the cutting action, maintaining a cleaner working environment.
