Juki LK-1900C Computer-controlled High-speed Bartacking Sewing System

Description

High-Speed Precision and Performance

The Juki LK-1900C Bartacking System delivers fast and accurate bartacking on a wide range of fabrics. Its computer-controlled system ensures consistent and uniform stitching, perfect for industrial and factory applications. Operators experience precise needle placement, smooth motion, and strong penetration on both heavy and light fabrics. The advanced motor design provides durability and long-lasting performance, reducing maintenance needs. This system minimizes errors, shortens production time, and increases efficiency. It is ideal for tailoring workshops, garment factories, and high-volume production lines. By combining speed with precision, the Juki LK-1900C Bartacking System enhances productivity while

Higher productivity

The LK-1900C has achieved the maximum sewing speed of 3,300 sti/min. The new mechanism contributes to increased rigidity of the machine driving section. In addition, greater speed is achieved through the reviewing of the lubrication System. The LK-1900CW (with a 1.8-fold capacity hook) runs at a speed of 3,000 sti/min.

 

Easier alignment of sewing positions

The “built-in LED marking light” facilitates positioning of bartacking to reduce unnecessary operation for placing the fabric. The irradiation width of the marking light is adjustable.
Some types of the work clamp foot may hide the irradiated light.

Standard LCD panel / Control box integrated with the machine head

JUKI designed and integrated the control box directly with the machine head. The machine includes 100 standard patterns, and operators can store up to 999 patterns (500,000 stitches) in memory. JUKI installed a new upright-type operation panel on the side of the machine head, allowing operators to control the machine without averting their eyes from the bartack being sewn. The table surface provides ample workspace. Operators can also install the operation panel on the table as before. If they choose to install it on the table, they must use an optional 1.6 m connecting cable (Part number: 40297363).

 

Movable eye guard device (optional)

The movable eye guard device protects eyes only during sewing. When the sewing machine is at rest, the eye guard automatically goes up to provide a clear view of the needle entry area, thereby allowing the operator to place the fabric smoothly.
Movable eye guard kit: Part number 40297869

 

Two-way data communication function for sewing machine data using an NFC terminal (optional)

The standard LCD panel is provided as standard with a USBport to facilitate data management between sewing machines and update of software. If you additionally use the optional NFC terminal, bidirectional data communication is enabled with a commercially-available Android terminal in a non-contact manner. This enables quick sharing of pre-set sewing data with other sewing machines to reduce the time required for set-up changing.
Optional NFC terminal: Part number 40289481
