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.

Higher productivity
The Juki LK-1903B/BR35 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.

Excellent seam quality.
Needle thread grasping mechanism helps produce consistent knot tying at the beginning of sewing.

Many different sewing patterns.
The Juki LK-1903B/BR35 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 Juki LK-1903B/BR35  is also able to sew buttons using the same data used for the LK-1903 (Data in EP-ROM are enabled by conversion).

The machine is provided as standard with the active tension (electronic thread tension control mechanism).
Since the Juki LK-1903B/BR35 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.
