*”sti/min” stands for “Stitches per Minute.

Increased productivity

• The MEB-3810 reduces the machine time by approximately 22%* due to its maximum sewing speed of 2,500 sti/min and its speed-up cloth cutting knife, thereby demonstrating increased productivity. Then newly adopted direct-driven main shaft by means of a compact AC servomotor not only achieves enhanced responsiveness, but also achieves both reduced noise and reduced vibration. In addition, the machine has adopted an air-driven cloth cutting knife which promises excellent responsiveness and operates faster than the conventional knife.
  *Condition: Number of stitches: 21 for the straight section (one side), 11 for the eyelet section; knife length: 22 mm

Improved workability and operability

• Improved viewability around the needle entry
  
  Projection of the arm frame of the machine head has been reduced. In addition, the cloth cutting knife is located closer to the operator side as compared with the conventional model. Viewability, when placing the material on the sewing machine, is improved, thereby contributing to improved workability. In addition, the thread clamp mechanism of the needle thread clamp (optional) has been improved for better viewability.
  
  
• Ease of placement of the material on the machine is increased
  
  The surface onto which the material is placed is flattened (for the machine with an overall thread trimmer). The material can, therefore, be placed on the machine with ease to improve workability.
• The machine is provided as standard with an LED light
  
  An LED light is provided as standard on the underside of the jaw of the machine head. The area around the needle entry is thus brightened to improve workability
• Achievement of lower vibration and lower noise
  Adoption of a direct-driven main shaft and a revamping of the curve sections of the thread take-up cam and looper cam contribute to remarkably reduced vibration and noise. Vibration has been reduced by 7.7dB* and noise has been reduced by 1.5dB* as compared with the conventional model to produce this operator-friendly machine.
  *Condition: Measured at the maximum sewing speed (MEB-3810: 2,500 sti/min; conventional MEB-3200: 2,200 sti/min)
• Retractable bottom cover
  
  A retractable bottom cover is adopted. Daily maintenance (threading, adjustment of the looper thread, cleaning, etc.) can be carried out without raising the machine head.

Quality improvement

• JUKI’s unique active tension
  
  For the needle thread tension control, JUKI’s unique active tension mechanism is adopted to electronically control the needle thread tension during the stitching cycle. As a result, improved seam quality is achieved. In addition, the sewing capabilities have been improved to prevent stitch skipping, as well as to produce well-tensed seams.
• Two different thread trimmers are prepared, i.e., the overall thread trimmer and the needle thread trimmer
  Two different thread trimmers are prepared. One of them can be selected according to the customer’s needs. The overall thread trimmer has been newly designed putting importance on productivity. It promises thread trimming without fail and trims the thread in a short time. The operator is no longer required to carry out fine adjustments of the thread trimmer when changing the sewing length. A sewing machine with a needle thread trimmer has been newly added to the MEB Series in response to customer needs.
