KM-250 Series
KM-250 Series
1-Needle, high speed, lock stitch machine with automatic thread
trimmer series developed through the advanced technology of
SunStar.
A new, higher level of advanced mechatronics has been ideally achieved
by the grafting of the newly developed, automatic thread trimming Fortuna
AC servo motor, equipped with the most up-to-date function, to our 1needle high speed lock stitch machine with automatic thread trimmer;
various functions created for operational convenience. This new product
will greatly contribute to upgrading sewing pattern quality and productivity
increase.
14mm
The thread take-up made of special
aluminum enables for maximum sewing
speed 5,500 spm (Normal speed 5,000
spm).
The high-performance impeller pulp is
used to enhance durability of the
internal moving section of the sewing
machine.
Feed dog's ideal trace and seaming structure
specially designed for Low tension sewing
minimize the puckering. At the same time,
straight of sewing is very excellent.
Thread-trimming mechanism increases
abrasion and durability with special material
of moving and fixed knife, The remaining
thread after trimming is minimized, leaving
the shortest remaining thread among similar
types of machine.
A number of accessories are offered to
improductivity. The soft-touch reverse
button and the attachment sheet
14mm lift of presser foot, highest
record among the sewing machines of
similar grade
KM-250AU series
The intensive research on feed dog
traces, thread take-up, needle bar and
thread adjusting device has resulted in
achieving good-quality sewing without
puckering, even when handling ultra
thin or new materials.
KM-250AU Series
KM-250B & KM-250BH Series
The engineering plastic inner oil
container made of special materials
completely bans sewing materials
from being tainted with oil. It is
suitable for high-end sewing materials.
Feeding & seaming mechanism not only
for medium thick material but also for
ultra heavy material guarantees powerful
stitching and perfect seaming.
Longer thread take-up stroke
7mm of maximum stitching length, both
make ultra heavy material stitching much
better.(KM-250B Series)
Compact-type auto knee lifter solenoid
attached directly to the machine head
in the back minimize loss of power.
It is connected and disconnected easily.
It also helps for better operation by
providing enough space in the lower
part of table (Option).
