Product overview
The LBH-1790AN Series follows the world's highest sewing speed and dry-head mechanism of its predecessor model. In addition, this machine comes with the latest model operation panel which is installed with a USB port. Futhermore, all drive mechanisms have been digitalized to manage each sewing pattern individually. The maximum sewing speed is 4.200 sti/min, and the junp speed is 200mm/s. The cycle time has been fther reduced for continuous sewing.

Management of sewing performance and sewing machine by the utilization of IoT (Internet of Things)

Data on sewing machine adjustments made according to the product to be sewn can be transferred to a commercially-available Android tablet incontactless mode. This enables quick check for uniform settings as well as confirmation of conditions of sewing machines in a sewing line, thereby facilitating setup changes. The operation panel is also provided as standard with USB port. Data management and software update can be carried out with ease using a USB thumb drive.
Excellent operability by Digitization
Higher productivity
The maximum sewing speed is 4,200 sti/min., and the jump speed is 200 mm/s. The cycle time has been further reduced for continuous sewing.
Cycle sewing and continuous sewing.
  • Cycle sewing
Twenty different programs can be registered, and as many as 30 different patterns can be stored in one program.
  • Continuous sewing                                                                                                                                                                  The machine is able to continuously sew two or more different patterns without requiring the work clamp foot to be lifted. As may as 20 programs can be registered, and six different patterns can be stored in one program. (Related parts need to be exchanged for optional ones.)
All drive mechanisms are electronically controlled
  • Electronic control of the material feed mechanism, needle feed mechanism, needle thread trimming mechanism, bobbin thread trimming mechanism, cloth trimming mechanism, presser lifter mechanism and other mechanisms has been achieved.
  • All adjustment values are digitalized to enable the operator to set and store those values on the operation panel.
Operator-friendly environment
  • Operation with reduced noise is ensured by the adoption of the direct-drive motor.
  • The illuminance of the LED light is adjustable and is located on the underside of the arm jaw. It is provided as standard for all models of the LBH-1790AN Series.
  • The sewing product can further be placed on the machine easily by installing the auxiliary table (standard accessory). In addition, the needle entry is located in the center of the bed, promising easier positioning of the sewing product.
Excellent seam quality by Digitization
JUKI's unique active tension (Electronic thread tension control system).
  • Needle thread tension for sewing parallel and bartacking sections of buttonholes can be separately controlled through the operation panel and stored in memory according to various sewing conditions (e.g., type of thread, type of material and sewing speed).
  • The machine is able to change the needle thread tensions at the parallel and bartacking sections of the buttonhole, to produce a beautiful buttonhole shape. This capability helps greatly in preventing thread breakage.
  • Needle thread tension is activated at the beginning and end of sewing. This prevents unthreading of the needle thread, and thread fraying that is likely to occur at the beginning of sewing.
  • Thread tension for basting stitching can be specified separately.
Basting stitch mechanism is effective for the production of beautiful buttonholes.
The basting stitch is effective on elastic materials such as knits. Basting stitch: Since the needle thread is tucked in without fail, it will never jut out of the buttonhole seams. Basting stitch can be sewn by nine rounds.
The machine is equipped with a multiple knife-dropping function.
  • Thanks to the multiple knife-dropping function, it is no longer required that the knife be changed at the time the buttonhole size is changed. The number of knife dropping times can be automatically set according to the buttonholing size in cases where the buttonhole size is frequently changed for small-lot productions or during the cycle sewing of buttonholes that are different in size.
  • The double-acting stepping motor type knife mechanism is free from the faulty dropping/returning of the knife.
  • The knife supports sewing lengths of 41mm at the maximum. In addition, knife mechanisms for 70mm and 120mm are optionally available.
Sewing settings can be easily changed.
  • For a changeover between purl stitch and whip stitch, threading of bobbin, as well as the bobbin thread tension need to be changed.
  • For double stitching, the bartacking section is skipped and only the parallel sections are sewn twice. This prevents any excessively tight finishes in the bartacking section of the buttonhole.
    First- and second-round stitches can be sewn using different stitch widths.
Improved maintainability
The machine eliminates oil stains on the sewing product
Thanks to our advanced dry-head technology, no lubrication is required except for the hook section. This eliminates oil stains on the sewing product.
The machine can be completely changed into a dry-head machine by replacing the hook with an optional non-lubricated hook. (In this case, the maximum sewing speed will be 3,300sti/min)
