Computer-controlled, High-speed, Lockstitch Buttonholing Machine
LBH-1790
● The hollowed type frame promises efficient sewing of vertical
buttonholes. The machine can be operated with its head
positioned horizontally.
● 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).
● Thanks to our advanced dry-head technology, no lubrication is
required except for the hook section.
