LBH-1790S
Computer-controlled, High-speed, Buttonholing Machine
Description
This sewing machine is provided as standard with the voice-guidance system with
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 sewing machine, though the initial setting is required.
|
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. |

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