Product overview

Product features

  • Machine is mounted with inbuilt NFC (Near Field Communication) and communication devices capable of a 2-way data transmission

    Data on sewing machine adjustments made according to the product to be sewn can be transferred to a commercially-available Android tablet in contactless mode. This enables quick check for uniform settings as well as confirmation of conditions of sewing machines in a sewing line, thereby facilitating setup changes.
    The operation panel is also provided as standard with a USB port. Data management and software update can be carried out with ease using a USB thumb drive.
    Data items of sewing can be numerically managed to ensure “stable quality” and “reduction in time required for setup changes”. Quantified sewing data can be externally taken from the sewing machine using an Android tablet or USB thumb drive.
    *Android OS Version 6.0 is recommended to use JUKI Smart APP.
    (Operation is confirmed with respect to Versions 5.0 and later.)
    Contact JUKI distributor in your area for how to use the application software.

  • The sewing pattern best suited to the sewing product to be bartacked can be selected by single-key operation

    The machine is provided as standard with six different linear bartacking patterns. Since the sewing size can be easily changed, the optimal number of stitches and sewing size can be speedily selected according to the belt-loop width.  If the normally used patterns are assigned to the patterns keys, a desired pattern can be called up or changed with single-key operation.

  • The machine head has been designed with an emphasis on operability

    With its broadly curved feed bracket (presser arm), the machine permits easy placement of the material to be sewn. The slimly shaped bed and head design that allows free space under the arm demonstrates greater operability in handling materials on the machine and continuous processes. These features contribute substantially to increased productivity in belt-loop attachment processes.

Basic performance

  • Higher productivity

    The machine achieves sewing speed of 3,000sti/min. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time.

  • Excellent workability and operability
    (Low-noise and low-vibration)

    • The direct-drive head (with no belt), which is directly connected to a compact AC servomotor, achieves outstanding. This head helps create a comfortable working environment with reduced vibration and noise.
    • The arm section of the machine head is fitted with a hand pulley. This allows the operator to visually check the needle entry points.
  • Excellent seam quality

    Needle thread grasping mechanism helps produce consistent knot tying at the beginning of sewing. (This device has been factory-set to “invoking prohibited” status at the time of delivery.)

  • The sewing starting point can be corrected

    In cases where the needle entry point for button sewing is to be corrected, the sewing starting point can be corrected without the adjustment of the relevant mechanism.

  • Auto-lifter mechanism utilizing a system

    • The machine is provided as standard with auto-lifter that uses a stepping-motor system. This helps reduce operator fatigue.
    • It is also possible to change over the stroke of the auto-lifter from a onestep stroke to a double-step stroke, which offers easier positioning of a material on the machine. For the double-step stroke, an intermediate stopping height can be established on the operation panel.
    • The work clamp foot lift can be set to a maximum of 17mm. (Standard 14mm)
  • Oil stains are eliminated

    • Thanks to our advanced dry-head technology, the frame (needle bar and thread take-up) no longer requires lubrication. This prevents the material from being stained with lubricating oil.
    • Just a small quantity of clean oil is supplied from the oil tank to the hook.
  • Eco-friendly power saving

    An encoder is installed in the pulse motor, thereby achieving substantially improved power-consumption saving.

  • LED Light

    The LED light can adjust the light intensity to 5 levels, and Off setting is also possible. 
    The operator can set the brightness which is easy to work, improving work efficiency.
