JUKI LK-1903BN/BR35 automatic button sewing machine features:
1. Newly developed machine head, LK-1903BN is adopted
JUKI LK-1903BN/BR35 button sewing machine achieves sewing speed of 2700sti/min. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time.
With our original horizontal forced feed mechanism, the button carrier sets a button in position so that the operation is simplified. Furthermore, operator fatigue is reduced since what operator needs to do is only setting material and pressing a pedal.
2. OPERATION PANEL (Button feeder)
The variety of functions can be easily adjusted by the simplified operation panel.
Alarm lamp will be activated when problem is detected so that proper measures can be taken quickly.
3. 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 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.
4. Higher productivity
JUKI LK-1903BN/BR35 button sewing machine achieves sewing speed of 2,700sti/min. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time.
5. Excellent seam quality
Needle thread grasping mechanism helps produce consistent knot tying at the beginning of sewing.
6. Many different sewing patterns
The machine is provided as standard with 50 different sewing patterns. The machine permits easy changeover of sewing patterns for effortless execution of an inexhaustible range of sewing specifications.
The LK-1903BN is also able to sew buttons using the same data used for the LK-1903 (Data in EP-ROM are enabled by conversion).
7. The sewing starting point can be corrected
The sewing starting point can be shifted in the X/Y direction. This enables the correction of a sewing pattern in accordance with the presser foot configuration.
8. Oil stains are eliminated
Thanks to our advanced dry-head technology, the frame (needle bar and thread take-up) no longer requires lubrication. This prevents the material from being stained with lubricating oil.
Just a small quantity of clean oil is supplied from the oil tank to the hook.
9. Eco-friendly power saving
An encoder is installed in the pulse motor, thereby achieving substantially improved power-consumption saving.
10. Auto-lifter mechanism utilizing a system
JUKI LK-1903BN/BR35 button sewing machine is provided as standard with auto-lifter that uses a stepping-motor system. This helps reduce operator fatigue.
It is also possible to change over the stroke of the auto-lifter from a onestep stroke to a double-step stroke, which offers easier positioning of a material on the machine. For the double-step stroke, an intermediate stopping height can be established on the operation panel.
The work clamp foot lift can be set to a maximum of 13mm.
11. The machine is provided as standard with the active tension (electronic thread tension control mechanism)
JUKI LK-1903BN/BR35 button sewing machine is provided with an active tension mechanism, it is able to set a needle thread tension that matches various sewing conditions (such as thread, material and sewing speed) on the operation panel, store the data in memory and reproduce it.
The needle thread tension can be separated according to stitching type or portion of a seam, such as the beginning part of the seam, base stitched part, zigzag stitched part and end of the seam (fastening stitch).
When the operation panel is used in combination with the active tension, the needle thread tension can be set on a stitch-by-stitch basis. This helps eliminate undesired thread tension variations at a multi-layered part of a material or with sewing direction, thereby contributing to upgraded seam quality.
12. LED LIGHT
The LED light can adjust the light intensity to 5 levels, and Off setting is also possible. The operator can set the brightness which is easy to work, improving work efficiency.
