JUKI LBH-781 High-Speed Buttonhole Sewing Machine

High-speed industrial buttonhole sewing machine designed for producing clean, consistent and durable straight buttonholes on a wide range of garments. The JUKI LBH-781 is a single-needle lockstitch buttonholing machine widely used in garment factories for shirts, blouses, uniforms and general apparel production.

The machine is designed for reliable high-speed operation and produces high-quality buttonholes on ordinary woven fabrics as well as selected knitted materials. Its mechanical gear-change system allows adjustment of the number of stitches, while the automatic-lubricating full-rotary hook ensures smooth and dependable operation.

With a maximum buttonhole length of 22mm, the LBH-781 is particularly suitable for standard shirt and garment buttonhole applications. The work clamp can lift up to 12mm, allowing easier handling of thicker materials and multiple fabric layers. JUKI specifies a maximum sewing speed of 3,600 stitches per minute for the LBH-780 Series.
