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 781 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, which enhances ease of operation.
A newly introduced mechanism in the needle thread trimmer prevents interference with the positioning of buttonholes.
The work clamp can be lifted as high as 12mm.
The knife mechanism and stop-motion mechanism produce less noise
