Thread-trimming
mechanism guaranteed
strong cutting power
increases abrasion and
durability with special
material of moving and
fixed knife, thread-trimming
of super heavy-materials is
perfect because of cutting
power control.
For maximum sewing speed 5,500 spm
(Normal speed 5,000spm)
- Selected phosphor bronze material for
bushing of important parts.
- Used special aluminum needle bar and
thread take-up lever.(KM-250A Series)
The unique threadtrimming mechanism
has simple design and
easy control system.
Feed dog's ideal trace
and seaming structure
specially designed for
light material sewing
minimize the puckering.
At the same time,
straight of sewing is very
excellent.
(KM-250A Series)
• This machine is designed for much
better conditions of feed dog's feeding
trace, thread take-up & needle bar's
stroke and tension adjusting.
So, fantastic stitching can be done.
• In sewing the high-valued material,
goods are not contamination by oil owing
to non-oiling hook. (KM-250AU 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).

Synchronizer installed in
pulley is more simple and
operated easy.
Advanced auxiliary automation system upgrades productivity.
It's most remarkable strengths are.
• Up-down-up wiper mechanism designed for easier operation
• B/T button system which proves soft touch.
• Powerful B/T solenoid which minimize loss of power.
