JUKI LK-1900B Series

Description

Computer-controlled, High-speed, Bartacking Machine

Higher productivity.
The Juki LK-1900B achieves sewing speed of 3,200sti/min. The machine’s starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time.

Excellent workability and operability. (Low-noise and low-vibration)
The direct-drive head (with no belt), which is directly connected to a compact servomotor, achieves outstanding. This head helps create a comfortable working environment with reduced vibration and noise.

The arm section of the machine head is fitted with a hand pulley. This allows the operator to visually check the needle entry points.

Excellent seam quality.
Needle thread grasping mechanism helps produce consistent knot tying at the beginning of sewing. (This device has been factory-set to “invoking prohibited” status at the time of delivery.)

The machine is provided as standard with the active tension (electronic thread tension control mechanism).
Since the Juki LK-1900B 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 IP-420U 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.
