Monitoring the pressure on take-up lever during the sewing operation

By detecting the pressure on take-up lever during the operation,every stitching condition can be monitored. It will help discover defective items such as skip stitches and fiber stitches.

Monitoring the changes of material thickness during the sewing operation

In addition to detecting material placement mistake, the machine can monitor the changes of material thickness during operation. When the changes occur, it helps discover additional or misplaced fabric.

Save the sewing results

The data of take-up lever pressure and materials thickness can be accumulated into the sewing machine. It allows to utilize the data for quality control as well as for reliable data source to your clients. It is compatible with the company FA products which makes it possible to display data in a real time.

Reduces skip stitches at start of sewing

Even the remaining thread is short, it reduces skip stitches which may occur at the start of sewing cycle.

Improves appearance (bird's nest) at start of sewing

The remaining thread tail when trimming is adjustable to a certain length. It greatly reduces the case of bird's nest by adjusting the amount of thread tail on the back of the fabric.

Fabric presser with optimal pressure

A new motion control allows the presser foot to press down on various types of fabric, from thin to thick materials, with optimal pressure.

Optimizes thread tightness in all stitching directions

This function reduces variation in tightness according to the stitching direction and improve quality.

Faster and more attractive

The world’s highest class of actual sewing speed is achieved (as of April 2020).
Curves and large seams can be sewn quickly and beautifully.

Automatic checking of setting mistakes

The sewing machine checks the thickness of the fabric and detects setting mistakes prior to sewing.
The oiling timing of the hook is digitized to ensure proper oiling and prevent excessive oil use.

Excellent energy-saving effects

The new arm bed structure and new XY feed control realize low vibration and low sound, and thereby realize energy savings.

Stable thread interlocking from the first stitch

“Stitch interlock faults” are resolved by minimizing the flapping of fabric at the start of stitching.

Detects stitching errors

In addition to visual detection by the operator, stitch errors (skipped stitches, thread breaks) are detected by the machine to help discover defective items.
*This function does not warranty all abnormal stitch detections. Depending on the sewing conditions, there may be undetected or false detection.

Faster adjustment of presser foot height

The height of the presser foot is adjusted after automatically measuring the overall fabric thickness along the stitching pattern.

Faster adjustment and reproduction of past adjustments

The hook, presser foot, and thread trimmer are digitally adjusted.

Open/close window for bobbin exchange

Unlike conventional large models which required the operator to get under the sliding plate to replace the bobbin, the J series models have an open/close window on the sliding plate so that the bobbin can be easily exchanged. This greatly reduces the operator’s work.
