The machine eliminates oil stains on the sewing product.
● Thanks to our advanced dry-head technology,
no lubrication is required except for the hook
section. This eliminates oil stains on the
sewing product.
● The machine can be completely changed into
a dry-head machine by replacing the hook
with an optional non-lubricated hook.
(In this case, the maximum sewing speed will
be 3,300rpm.)
JUKI's unique active tension (Electronic thread tension control system).
● Needle thread tension for sewing parallel and bartacking
sections of buttonholes can be separately controlled
through the operation panel and stored in memory
according to various sewing conditions (e.g., type of
thread, type of material and sewing speed).
● The machine is able to change the needle thread tensions
at the parallel and bartacking sections of the buttonhole,
to produce a beautiful buttonhole shape. This capability
helps greatly in preventing thread breakage.
● Needle thread tension is activated at the beginning and
end of sewing. This prevents unthreading of the needle
thread, and thread fraying that is likely to occur at the
beginning of sewing.
● Thread tension for basting stitching can be specified
separately.
Frame shape offers improved operability.
● The hollowed type frame promises efficient sewing of vertical buttonholes.
The machine can be operated with its head positioned horizontally.
● The distance from the machine arm to the needle has been lengthened and
the left side section of the needle entry has been reduced by a large margin.
This helps in the smooth placement of the sewing product on the machine,
thereby ensuring improved workability.
