1-needle, Lockstitch Buttonholing Machine LBH-780
LBH-780NV(for
double-stitching with gimp)
LBH-780NB(for
double-stitching with gimp and gimp cutter) Smooth operation contributes to high-quality
finished buttonholes and a higher degree of efficiency
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.
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.
This needle entry point can visually
checked. This permits easy positioning
of buttonholes.
The lift of the work clamp is as high
as 12mm.
