Description

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 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.

Features

• 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
• 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
• Work clamp can be easily lifted. This helps to substantially reduce operator fatigue
• The pressure required to depress the start pedal and lifter pedal has been reduced. This helps to dramatically reduce operator fatigue
• 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
