Juki LU-2860V-7

Semi-dry Direct-drive, 2-needle, Unison-feed, Lockstitch Sewing System with automatic thread trimmer (Vertical axis 2.0 fold-capacity hook / 12 mm - pitch type)

The LU-2800V-7 Series are high-performance sewing machines that have been digitized for easier set-up and operation . It leaves a shorter thread on the material at the beginning of sewing by means of the needle thread clamp device, as well as at the end of sewing by means of the thread trimmer. Thanks to the adoption of a 2.7-fold hook (LU-2828V-7), the frequency of bobbin thread changing is reduced and work-ability is improved. Perfect parameters needed to achieve a high quality seams can be set digitally and key conditions do not need to be manually adjusted. Thanks to this digitalization, optimum adjustment values required to produce high-quality seams can be stored on a material-by-material basis in the machines internal memory and can be reproduced with ease.

High and long arm has been adopted. The machine is suited to sew car seats, sofas and bags. It is a sewing machine provided with dramatically improved workability and functions which are required for sewing large products and extra heavy-weight materials.

The maximum stitch length is 12 mm

This model is the most-desired sewing machine for sewing furniture such as sofas. It is best-suited to topstitching with a stitch length of maximum 12mmpitch. During the topstitching process, the longer distance from the machine arm to the bed, in particular, effectively demonstrates the machine's improved workability.

Standard equipment

Adoption of the needle-thread active tension

Needle tension is digitally controlled

Needle thread tension which matches sewing conditions given can be set on the operation panel and stored in memory. The needle thread tension adjustment needs experience. However, for this sewing machine, thread tension data stored in memory is reproducible, thereby reducing the setup time when the product to be sewn is changed.
Example: Needle-thread active tension demonstrates its effectiveness in the topstitching process.

Active presser foot pressure mechanism

The presser foot pressure is digitally controlled

Digital control system controls the presser foot pressure. Under the automatic mode, the multi-layered section detection function detects changes in material thickness to increase/decrease the presser foot pressure accordingly. Under the manual mode, the presser foot pressure control function is assigned to the hand switch to enable operation with the hand switch.

Best-suited stitches are produced at multi-layered parts of material.

Multi-layered part detection function

Multi-layered parts of material which occur in the case two or more plies of material are sewn or different kinds of material are sewn can be detected by the multi-layered part detection function to change over the stitch length, thread tension, presser foot presser and amount of alternate vertical movement to those that have been predetermined for sewing those parts of material.

Setting of thresholds for the multi-layered part detection

Under the teaching mode for the multi-layered part changeover ON sensor value, the material thickness at the normal part and that at the multi-layered part of material can be measured with ease.
The automatically-measured thresholds can be set as those for the multi-layered part detection.

Multi-functional 6-string switch

Sewing conditions can be changed to the best-suited ones only with the one-touch changeover switch.

The sewing data (stitch length, needle thread tension, amount of alternate vertical movement, presser foot pressure and sewing speed) can be changed easily with the one-touch changeover switch to obtain the ones that have been elaborated according to sewing conditions.
The sewing data (stitch length, needle thread tension, amount of alternate vertical movement, presser foot pressure and sewing speed) can be changed easily with the one-touch changeover switch to obtain the ones that have been elaborated according to sewing conditions.
Four different one-touch functions can be assigned to six-gang hand switches ① to ⑥, touch-back switch and jog dial, at the maximum.
(*For the initial settings, the one-touch functions are assigned to 6-gang switches ① to ③.)

Improvement of operability by means of the jog dial

The operator is able to turn the main shaft (for moving the needle bar up and down) only with the jog dial without stretching his/her arm to the handwheel.
When the jog dial is pushed, it can be used as 1/2 needle-stitch correction switch (one touch function).

Management of sewing performance and sewing machine with JUKI’s next-generation sewing system.

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

Management of sewing performance and sewing machine by the utilization of IoT (Internet of Things)

Management, browsing and editing of data can be carried out on the application software

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.

Adjustment of sewing condition is displayed on one screen

Sewing conditions can be set easy since sewing conditions such as thread tension, stitch length, presser foot pressure, alternate vertical movement amount, etc. are displayed on one screen.
