Juki LBH-783 Single Needle Lockstitch Buttonholing Industrial Machine
Includes Fully Assembled Table and Swervo Motor
Smooth operation contributes to high-quality finished buttonholes and a higher degree of efficiency.
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 Juki 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.
Assembled Table & Servo Motor
This Package includes a Fully Assembled Table and a Servo Motor.
Adjustable Buttonholing Position
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.
12mm Work Clamp Lift
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.
Reduced Operator Fatigue
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.
Silent Operation
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.
The machine neatly tucks in tetron gimps with consistency
Thanks to the improved locus of the gimp guide, the single needle lockstitch industrial sewing machine is flexibly adaptable to changes in the types of gimps to be used, easily switching operation to accommodate one to three pieces of tetron thread, or one sewing thread and one span thread. In addition, the gimp guide is designed so that it shifts vertically. This means that the relation between the needle and the gimp guide is uniform even if the material thickness varies, thus allowing the machine to tuck in gimps with consistency.
A machine is designed for sewing soft-to-the-touch circular bartacks
It has been developed to sew circular bartacks on ladies' wear, a process that requires a very delicate finish.
The machine ensures stable stitching performance on multi-layered portion of the material
The improved work clamp and its fulcrum securely hold multi-layered portions of a heavy-weight material, thereby preventing sewing troubles such as uneven material feed, slip-off of gimp and needle breakage. This allows the single needle lockstitch industrial sewing machine to perform buttonholing with consistency.

Motor Options
Clutch motors operate at a fixed speed, typically between 1725 - 3450 rpm, depending on the type of machine. Servo Motors on the other hand are speed adjustable. The two major advantages of the Servo Motor are that you can control the speed of the motor and that the motor is completely silent when the pedal is not engaged.
Some other advantages of the Servo Motor include:
- They consume up to 90% less energy than clutch motors
- 1/3 lighter than clutch motors
- Reverse motor rotation with the flick of a switch
- Nothing to wear or adjust
- Adjusted speed remains the same no matter how hard the pedal is pressed
Most of our customers find that the sewing machine is much easier to control with a Servo motor because of the speed control. This is especially helpful for beginner sewers but also for projects that simply don't require high speed stitching.
