Juki MB-1800S Chainstitch Button Sewing Machine

Description

High-Speed Chainstitch Performance

The Juki MB-1800 Chainstitch Button Machine delivers fast and accurate single-thread chainstitching for button sewing in industrial applications. Its dry-head design eliminates oil stains on garments while maintaining smooth operation. Operators benefit from precise needle control and consistent fabric handling. The machine supports high-speed production while reducing cycle time, making it ideal for both small-lot and mass-production environments. Production teams can achieve uniform, high-quality stitching with minimal operator fatigue, improving overall workflow and efficiency.

• Excellent seam quality and improved flexibility

  It comes with direct-drive electronic feed driven by a compact AC servomotor to guarantee excellent seam quality and dramatically improve flexibility and maintainability.

• The machine is able to independently sew various stitching shapes such as U-shaped stitching, X-shaped stitching and Z-shaped stitching

  • The machine provides fifty-five different stitching patterns as standard. In addition to the sewing shapes, the operator can change the buttonhole intervals and the number of stitches on the operation panel. The machine fully supports many different button specifications, increasing its range of applicability, reducing costs associated with specification changes, and freeing the operator from adapting the machine to different specifications. Operators can create custom patterns on the PGM-20 and then use them on the sewing machine.

  

• Shorter lengths of thread remain after thread trimming

  The machine performs thread trimming at the optimal position by correcting the button position with respect to the needle entry of the last stitch. This shortens the thread remaining on the material after thread trimming to approx. 3.5 mm.

• The dry-head eliminates oil stains

  The machine head is a non-lubricating type. With this type, the operator never has to add oil, and staining of the sewing product with oil is an impossibility.

• The machine sews buttons with beautifully finished seams

  • The machine adopts a stitching pattern with the tying stitch only at the final stitch. This ideal stitching pattern optimizes single-thread chain stitching to produce beautiful seams on the wrong side of the material, thereby guaranteeing excellent seam quality.
  • Moreover, since the machine uses significantly fewer mechanical parts, troubles caused by excessive play in the feed such as needle breakage and button breakage occur for less often.

• The machine comes standard with a thread-fray-prevention function.

• It uses a solenoid-operated thread-tension-changeover system to prevent thread fraying. Since the machine uses a long needle (TQ×7), operators can use the thread-fray-prevention function for sewing shank buttons. Operators can turn the thread-fray-prevention mechanism ON or OFF by setting the solenoid drive accordingly.

• The machine offers outstanding productivity

  The machine runs at a maximum sewing speed of 1,800 rpm and comes with a direct-drive system supported by a compact AC servomotor that offers excellent stopping accuracy and responsiveness. Working in combination, these features shorten the machine time by 10 % or more compared with our conventional machine.
  Needless to say, the single-thread, chain stitch, button sewing machine does not need bobbin thread changing.

• Excellent maintainability and operability

  • Thanks to the elimination of the mechanical structures such as the stop-motion mechanism and feed cam, the machine operates with less vibration and noise and requires no maintenance.
  • The foot pedal can be operated with reduced pressure from the operator’s foot. This helps reduce operator fatigue by allowing the operator to operate the machine more rhythmically.

  

• The machine responds to many different button-sewing specifications
