Juki Sewing Machine

Model LBH-1790SS 

Juki Electronic Buttonhole Industrial Sewing Machine


The LBH-1790S is the newest Juki button-holing machine and the latest addition to the Juki Simply Smart Series lineup. This model allows for the unrivaled quality one comes to expect with Juki but contains economical features. With a simple panel interface and powerful built-in motor, it is one of the most reliable button-holing machines available on the market today.

Higher Productivity

This sewing machine achieves higher productivity with its improved capabilities such as the maximum sewing speed of 4,200 sti/min, quick acceleration at the beginning of sewing and quick deceleration at the end of sewing, increased thread trimming speed, and auto-lifter performance.

Multiple-Times Knife Dropping

Thanks to JUKI's unique multiple-times knife-dropping function, knife replacement is no longer required even when the buttonholing size is changed. In the case of small-lot production, frequent changes in the sewing size and/or sewing of different cycle sewing patterns with different sewing sizes are required. In such a case, the number of times to drop the cloth trimming knife is automatically set according to the buttonholing size.

Easy Changeover of Sewing Settings

Changeover between purl stitching and whip stitching and between single stitching and double stitching can be carried out with ease.

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 electric-driven mechanism has been adopted for the work clamp foot lifter, needle/bobbin thread trimmers, work clamp foot pressure regulator, cloth trimming knife, and thread tension controllers, thereby ensuring stable sewing that produces beautiful seams with less operating noise.

Standard Operation Panel (New Model)

  • Setting of functions such as the pattern number and the needle thread tension can be entered through the operation panel with ease. It is also possible to easily change the distance between buttonholes by means of the enlargement/reduction function.
  • The operation panel is provided as standard with a USB port. This means that the sewing machine data management and software updating can be carried out with ease by means of the USB port.

Voice Guidance for the Operator

This sewing machine is provided as standard with the voice guidance system with a clock function.
The voice guidance can be used for the purpose of production support such as giving the operator information about the number of pieces produced, work progress management, and the operation rate of a sewing machine, though the initial setting is required.

31 Different Buttonhole shapes are provided as standard

As many as 99 different sewing patterns can be stored in memory.
The sewing patterns that are stored in memory can be selected as desired through the operation panel.
