Juki LBH-1790S-S Electronic Button Hole

Juki LBH-1790S-S

Computer-controlled, High-speed, Buttonholing Machine

Operability that promises ease of use

The work clamp foot lifting height can be set as desired. The work clamp foot can be lifted as high as to 17 mm by the use of the reverse-rotation needle-up function.

Handling and placement of the sewing product is further improved by installing the auxiliary table (supplied as standard with the sewing machine). In addition, the needle enters the center of the bed, contributing to easier positioning of the sewing product.

Quietness of the sewing machine during sewing is ensured by the direct-drive motor.

JUKI's established quality is achieved with simplified functions

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 the auto-lifter performance.

Multiple-times knife dropping

Thanks to JUKI's unique multiple-times knife dropping function, the knife replacement is no longer required even when the buttonholing size is changed. In the case of small-lot production, frequent change 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 are 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.

Basting stitch on elastic materials

The basting stitch is effective on elastic materials such as knits.

Main functions driven electrically

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.

Active tension

The needle thread tension can be separately set for the parallel section and bartacking section of the buttonhole seam according to various sewing conditions (thread, material, sewing speed, etc.) given, and those setting data can be stored in memory.

The needle thread tension can be changed over at the parallel and bartacking section of the buttonhole seam without fail, thereby producing beautifully-finished buttonhole stitch shape.

The needle thread tension to be employed at the beginning and end of sewing can be set individually. This helps prevent slip-off of the thread at the beginning of sewing and unravel of the finished seam.
