The sewing machine complies with the "Juki Group Green Procurement Guidelines" on the use of
hazardous substances, which is stricter than other restrictions, such as those of the RoHS Directive.
As compared with the conventional model, the LK-1900AN reduces noise by 3.9dB and vibration by 1.65dB.
The RoHS Directive is an EU Directive limiting the use of 6 hazardous substances (lead, hexavalent chromium, mercury, cadmium, PBB and PBDE) in electrical and electronic equipment.
The Juki Green Procurement Guideline is the voluntarily established criteria to eliminate not only the aforementioned six substances, but also other ones which also adversely affect the environment.

Active tension
The machine runs at 3,200sti/min, faster than any other
sewing machine ever made.
In addition to the high-speed sewing performance,
cycle time can be substantially decreased (reduced
approximately 30% compared to our predecessor model:
For 42-stitch large bartacks).
Higher productivity.
Since the 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 IP-410B 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.
The machine is provided as standard with the active
tension (electronic thread tension control mechanism).
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 just clean oil is supplied from
the oil tank to the hook.
Oil stains are eliminated.Wider sewing area and
many different sewing patterns.
The main shaft and the thread take-up lever mechanism
have been reworked to enable the reduction of noise
and vibration. As compared with the conventional model
LK-1900A, the noise is reduced by 3.9 dB and the
vibration is reduced by 1.65 dB.
The machine comes with a newly developed needle
thread grasping mechanism. The mechanism prevents
thread from slipping off from the needle eyelet at the
beginning of sewing, from tangling on the wrong side
of the material and also being stained during sewing.
The thread trimming mechanism has been further
improved to shorten the length of thread remaining
on the wrong side of the material after thread trimming.
Excellent seam quality.Reduction of noise and vibration
With its 30mm (length) by 40mm (width) sewing area,
the machine can sew many different shapes of bartacks.
The machine is provided as standard with as many as
50 different types of sewing patterns including semilunar
bartacking, round bartacking, radial tacking as well as
conventional bartacks.
The LK-1900AN is also able to sew bartacks using the
same data used for the LK-1900 (EP-ROM).
