The Juki LBH-1790S 

is a world-class electronic buttonhole machine that represents the gold standard in apparel finishing. By replacing complex mechanical cams with a sophisticated Computer-Controlled (CNC) system, this machine allows operators to switch between different buttonhole shapes and sizes at the touch of a button. Featuring Juki's legendary build quality and an integrated direct-drive motor, the LBH-1790S provides high-speed performance (up to 4,200 SPM) with significantly reduced noise and vibration, ensuring perfect, consistent stitches on everything from fine silk blouses to heavy workwear. 

  • Programmable Stitch Patterns: Stores up to 99 different patterns in memory. Easily switch between square, radial, and eyelet buttonholes without changing mechanical parts. 
  • Electronic Tension Control: The "Active Tension" system allows you to set different tensions for the parallel sections and bartack sections of the buttonhole, ensuring a flat, professional finish on any fabric. 
  • Multiple-Sizing Capability: The unique "Multiple-Sizing" feature allows the machine to sew buttonholes of different sizes without changing the knife, perfect for garments with varying button diameters. 
  • Basting Stitch Function: Provides a basting stitch option that is effective on elastic materials to prevent the fabric from stretching or slipping during the buttonhole cycle. 
  • Integrated Direct-Drive Motor: The motor is connected directly to the main shaft, providing 90% energy efficiency, instant start/stop response, and an incredibly quiet sewing environment. 
  • Large Color Operation Panel: Features an intuitive LCD touchscreen that allows for easy adjustment of stitch width, length, and pattern selection.

JUKI DDL-8700 FAQs

What kind of needles do you use in the DDL-8700?

The needles with your JUKI are the Organ DBx1, available on our website. This machine uses size 16×257, size 8 through 20 or 16×97. The 8700 can also use standard needles, sizes 9 through 21, universal or fabric-specific needles such as knit.

Where does the machine oil go?

A pan directly underneath the machine supplies oil to the machine with a cotton wick. Lift the machine up and over to access the oil tank while on the table. You must keep the machine’s oil level consistently at the «high» mark, either by adding more oil or draining it and refilling it as needed. If the oil pump can’t get the oil into the machine, it can cause serious problems later.

What kind of oil does this machine require?

You need a specific type, like motor oil in your car, to keep this machine running. The DDL-8700 requires JUKI New Defrix Oil No.1, equivalent to ISO VG7.

What size table can I get with this machine?

Our table has legs and is 22"w x 47"l. It includes a knee and foot pedals and a left-hand drawer for accessories.

Does the DDL 8700 make buttonholes?

No. The 8700 only does straight stitching, with a horizontal bar on the right side for a reverse stitch.
