LBH-1790ANS Computer-controlled, High-speed, Buttonholing Sewing System
Management of sewing performance and sewing machine with JUKI’s next-generation sewing system. Machine is mounted with inbuilt NFC (Near Field Communication) and communication devices capable of a 2-way data transmission.
Shorter – thread remaining mechanism (LBH-1790ANB)
The length of remaining bobbin thread becomes shorter, less than 2.5mm on average
The newly-developed shorter-thread remaining mechanism trims the thread short and eliminates the trouble of manual thread nipping.
Management of sewing performance and sewing machine by the utilization of IoT (Internet of Things)
Management, browsing and editing of data can be carried out on the application software
Data on sewing machine adjustments made according to the product to be sewn can be transferred to a commercially-available Android tablet in contactless 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 a USB port. Data management and software update can be carried out with ease using a USB thumb drive.
Data items of sewing can be numerically managed to ensure “stable quality” and “reduction in time required for setup changes”.
Quantified sewing data can be externally taken from the sewing machine using an Android tablet or USB thumb drive.
*Android OS Version 6.0 is recommended to use JUKI Smart APP.
(Operation is confirmed with respect to Versions 5.0 and later. )
Contact JUKI distributor in your area for how to use the application software.
