With its new electronic feed system, the operator can
select and use the sewing pattern entered.
When changing a sewing pattern, the conventional
mechanical bartacking machine requires the replacement
of a feed cam. Since the new electronic machine no
longer uses a feed cam, this operation is no longer
necessary and costs are substantially saved.
The machine demonstrates a high-speed sewing capability
of up to 2,200rpm and dramatically increased productivity.
The machine is equipped as standard with a full-rotary
3 fold-capacity hook. The hook reduces the frequency
of the bobbin thread replacement, enhancing efficiency
in sewing with thick thread.
The following features promise improved sewing
capabilities for extra heavy-weight materials: A high-
power, direct-drive motor that drives the needle with
increased material-penetrating force; a higher-torque
stepping motor that increases the feed efficiency, and
a pneumatic work clamp that increases the material
clamping force.

The thread trimmer offers outstanding reliability and
durability. The ideal application for the device is the
sewing of seatbelts with thick synthetic threads.
Unlike the thread trimmer using a knife, the heat cutter
trims thick thread without fail and shortens the thread
remaining at the seam end.
durability to cut down on maintenance requirements.
The heat cutter is designed to leave no thread chips on
the hot wire section. This ensures consistent thread
trimming at all times.
LK-1942
By equipping the LK-1942 as standard with an intermediate
presser to prevent the material from flopping, beautifully
finished seams are almost guaranteed.
The height and stroke of the intermediate presser are both
adjustable.
It also offers improved
