LBH-780 Series
1-needle, Lockstitch Buttonholing Machine
Description
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. |
