Presser foot for vertical bartacking is supplied with the unit as an accessory.
Higher productivity.
The machine 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 AC 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.
LK-1900B
Series
Many different models are prepared according to the type of materials.
S type (Bartacking pocket lip of suits)
H type (Bartacking crotch of jeans)
F type (Attaching the shoulder straps to brassier)
M type (Bartacking shoulder of running shirt)
Excellent seam quality.
Eco-friendly power saving
An encoder is installed in the pulse motor, thereby achieving
substantially improved power-consumption saving.
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.)
Auto-lifter mechanism
utilizing a system.
The machine is provided as standard with auto-lifter that uses a
stepping-motor system. This helps reduce operator fatigue.
The work clamp foot lift can be set to a maximum of 13mm.
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 sewing starting point
can be corrected.
In cases where the needle entry point for button sewing is to be
corrected, the sewing starting point can be corrected without the
adjustment of the relevant mechanism.
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.
Many different sewing patterns.
The machine is provided as standard
with the active tension
(electronic thread tension control mechanism).
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-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.
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-1900B is also able to sew buttons using the same data
used for the LK-1900 (EP-ROM).
Active tension
Higher productivity.
Low-noise and low-vibration.
LK-1900B-SS
The LK-1900B model comes in five different subclass models, such as S type (standard), H type (for heavy-weight materials), F type (for foundation),
M type (for knits and knitted materials) and W type (with a large shuttle hook for heavy-weight materials), to offer a choice according to any application.
The needle's penetrating force into the material has been increased. This provides an improved responsiveness to heavy-weight materials for the H type machine.
The W type has adopted a large shuttle hook, which reduces the frequency of bobbin-thread changing to enable highly efficient sewing work.
