LBH-780 SERIES
The buttonholing position can be easily adjusted.
enhances ease of operation.
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.
ease of operation is further improved.
The work clamp can be lifted as high as 12mm.
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.
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.

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.
gimp guide is designed so that it shifts vertically.
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.
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.
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.
cutting scissors and the needle scarcely changes when sewing multi-
layered portions of the material, thus ensuring consistent gimp-cutting
at any occasion.
