This newest and most advanced machine has been developed in the pursuit of upgraded seam

This newest and most advanced machine has been developed in the pursuit of upgraded seam
quality and improved workability in bottom hemming processes.
This newest and most advanced machine has been developed in the pursuit of upgraded seam
quality and improved workability in bottom hemming processes.
The machine offers excellent seam quality
and sewing capabilities.
Efficient workability.
●The needle bar stroke is as high as 35mm. This offers
increased penetration of the needle into the material to
improve adaptability to heavy-weight materials.
●The machine demonstrates excellent sewing capabilities,
when sewing heavy-weight denim or multi-layered
portions, that free it of sewing troubles such as stitch
gathering, stitch skipping and needle breakage.
●The machine is able to sew material with a low presser
foot pressure while preventing the material from flapping.
As a result, the material can be sewn free of puckering.
●The top- and bottom-roller style feed mechanism forms
seams with increased consistency to achieve improved
hemming quality while reducing uneven hems.
Highly consistent and reliable thread
trimmer mechanism.
●The machine employs a highly reliable horizontal
thread trimming mechanism which cuts thick
thread without fail.
●The entire knife unit can be installed/removed.
●The moving knife position can be easily adjusted.
●The knife unit is of a bed device type. This means
that adjustment of the knife unit is not required
after removing the throat plate.
●Every time that operation of the thread trimmer
occurs, the air blower keeps the knife clean by
blowing off thread chips from the blade, ensuring
the reliable operation of the thread trimmer.
●The machine has adopted a forced circulation mechanism in
consideration of reliable oiling and oil leakage prevention.
●The frame and cylinder-bed sections are provided with a circulation
feature to prevent oil leakage. In addition, to ensure reliable operation,
a gasket is fitted inside the frame, preventing any leakage of oil from
the needle bar.
●The machine comes with a newly designed needle bar sliding
mechanism that is highly durable and free of play.
●Coupled to the automatic presser lifter, the hemming binder
automatically opens/closes. This enables efficient operation.
●The binder can be adjusted both longitudinally and laterally.
●The binder can also be independently opened/closed by
operating the knee switch (knee lifter for machines without
a thread trimmer).
The lubrication mechanism effectively reduces oil stains
on the material.
Feed rollers, pressers, feed adjusting gears and binders from the UNION SPECIAL 63900 model machine can be
attached to the DLN-6390/-6390-7 with no additional machining or adjustments.
Parts from your current machine are also compatible with the DLN-6390/-6390-7.
●The machine is provided with a 1.7-fold hook,
which demonstrates remarkable productivity.
●The needle feed amount can be easily adjusted
with the scale dial, so as to get the best suited
seam quality when the material or thread is
changed.
✽ For machines DLN-6390 that are not provided with a thread trimmer,
the binder can be opened/closed simultaneously with the presser lifting
action by means of the knee lifter supplied with the machine.
