LBH-780 SERIES
LIST OF THE SUBCLASS MACHINES ACCORDING TO THEIR APPLICATIONS
APPLICATIONS
Buttonholing size (in mm)
At the very least, a good buttonholing machine should
finish seams of consistent quality and be widely
adaptable to many different kinds of materials and seam
specifications. The LBH-780 series buttonholing machines
respond to these needs and help reduce operator fatigue,
thereby finishing high-quality buttonholes with a higher
degree of efficiency.
The buttonholing position can be easily adjusted. This further
enhances ease of operation.
A newly introduced mechanism in the needle thread trimmer
prevents interference with the positioning of buttonholes. The shape
of the face plate is designed to provide sufficient clearance around
the needle entry position. As a result, ease of operation is further
improved.
The work clamp can be lifted as high as 12mm. The machine is
capable of sewing heavy-weight materials such as bulky knits.
The maximum lift of the work clamp is 12mm, enabling the machine
to make high-quality buttonholes in heavy-weight materials.
Work clamp can be easily lifted. This helps to substantially reduce
operator fatigue. The pressure required to depress the start pedal
and lifter pedal has been reduced. This helps to dramatically reduce
operator fatigue.
This needle entry point can visually
checked. This permits easy
positioning of buttonholes.

The knife mechanism and stop-motion mechanism produce less noise
when they actuate, thus contributing to a more comfortable working
environment. Thanks to the simple design of the stop-motion
mechanism and unique knife mechanism, the machine operates with
low noise. The machine starts, decelerates and stops smoothly.

MAQ-060000A0
Spacer for first bottonholes
This is a ruler to be used to set the first buttonhole at a predetermined position
in accordance with the shape of the collar.
Adjustable regardless of the dimensions and shape of collars.
Ladies' blouses
(for double-stitching with gimp)
Q061
MAQ-061000A0
(for double-stitching with gimp and gimp cutter)
Spacer for buttonholes on topcenter plaits
The machine neatly tucks in tetron gimps with consistency.
Thanks to the improved locus of the gimp guide, the machine is
flexibly adaptable to changes in the types of gimps to be used, easily
switching operation to accommodate one to three pieces of tetron
thread, or one sewing thread and one span thread. In addition, the
gimp guide is designed so that it shifts vertically. This means that
the relation between the needle and the gimp guide is uniform even
if the material thickness varies, thus allowing the machine to tuck in
gimps with consistency.
Q066
MAQ-066000A0 Buttonholes are
positioned at right angles
to the top-center plaits.
SK-1
A machine is designed for sewing soft-to-the-touch circular bartacks.
It has been developed to sew circular bartacks on ladies' wear, a
process that requires a very delicate finish.
Pneumatic knife driving unit
This is a ruler to be used for sewing lateral buttonholes in the process of
buttonholing top-center plaits.
The ruler is provided with four positioning pointers on the right and left.
Each of the pointers can be shifted with a single motion.
The SK-1 pneumatic knife driving unit cuts the material by tapping a flat knife
and nylon plate on the material. This prevents the tensing-up of texture yarns
that so often occurs when sewing glossy synthetic materials.
LBH-783NB
The machine ensures stable stitching performance on multi-layered
portion of the material. The improved work clamp and its
fulcrumsecurely hold multi-layered portions of a heavy-weight
material, thereby preventing sewing troubles such as uneven material
feed, slip-off of gimp and needle breakage. This allows the machine to
perform buttonholing with consistency.
Q060
The gimp cutter dramatically promotes lobor-saving. (NB type)
The length of remaining gimp after its trimming is only about 2mm.
This eliminates the thread cropping procedure in the after-process,
thereby increasing productivity. The distance between the gimpcutting scissors and the needle scarcely changes when sewing multilayered portions of the material, thus ensuring consistent gimpcutting at any occasion.
Q066
