Juki LBH-780 Single Needle, Lockstitch Buttonholing Machine

Home Portfolio Juki LBH-780 Single Needle, Lockstitch Buttonholing Machine

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

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.

Work clamp foot lifting height

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.
