Electronically Controlled Pattern Sewing Machines
Optimizes thread tightness in all stitching directions
Digital tension function
The sewing machine selects the optimum tension according to the stitching pattern. They reduce variation in tightness according to the stitching direction and improve quality. This function is ideal for difficult circle stitching and stitching in the hitch direction.
Digital reproduction of the aesthetic sense of skilled workers The basic adjustments are the same as a conventional machine, so there is no need to learn new operation methods. Conventional knob settings may be kept as they are while stitching using the digital function.
When sewing safety belts, the fabric becomes harder as the stitching progresses. By gradually increasing the tension, stable stitches can be realized with each stitch.
Realizes stable thread interlocking from the first stitch
Prevention of skipped stitches at startup (e-stitch)
Stitches are smoothly interlocked from the start of stitching. "Stitch interlock faults" are resolved by minimizing the flapping of fabric at the start of stitching. "Stitch entanglement," which occurs on the back of the fabric at the start of stitching, is minimized.
Inevitable stay stitching can be minimized. Stay stitches can be minimized by using the presser foot to firmly press down on thin fabrics that are difficult to interlock.
This function is useful for stitching on materials that are difficult to stay stitch, while maintaining stitching quality.
Enhance decorative stitching with a beautiful finish that does not require stay stitches.
Supports larger stitching areas
Extra-thick stitching of larger areas
With an increased stitching area, you can perform multiple steps for full harnesses and lashing belts in one stitching session.
Speed is been increased by 1.5-times compared to conventional extra-thick stitching. The increased stitching area and increased speed will greatly shorten cycle times.
* Supported by PLK-J4040RH/J10050RH only
Realizes beautiful stitches using diverse adjustment functions
Independent presser foot
A presser foot optimally presses down on all fabrics, from thin to thick. The presser foot, which directly affects the stitching state, allows free motion, so beautiful and stable stitches can be achieved.
Stitching tension can be smoothly adjusted in the operational panel.
The fabric pressing time and timing can be adjusted digitally. The fabric is pressed at an optimum timing to prevent the fabric from lifting up. This contributes to stable needle location and reduced stitch skipping.
Automatically adjusts presser foot height
Featuring an MT
tracer beautiful stitching finish The presser foot adjusts its height after automatically measuring the overall fabric thickness along the stitching pattern. Although it was necessary in the past for workers to manually adjust the presser foot height of each location where fabric thickness changes occurred, the use of this function enables the time and effort necessary for such a process to be drastically reduced.
This function is useful for sewing materials with numerous locations of varying thickness.
* This function does not guarantee that the optimal presser foot height for the fabric being sewn will be achieved. After measurements are performed, fine adjustments may be necessary in some cases.
Automatically discovers setting errors
The sewing machine checks the thickness of the fabric and detects setting errors before beginning sewing. The presser foot moves along the stitching pattern and confirms the thickness, so valuable fabric is not wasted.
Even materials 0.01mm thin can be detected. The sewing machine double-checks all conventional settings that are made manually.
Accurately detects stitching errors
Thoroughly prevent rejects Stitch errors are discovered beforehand. The stitch errors (skipped stitches, thread breaks) that occur during stitching are detected by sensing the tension applied on the hook.
This function stops the sewing machine so rejects can be found at an early stage.

Enables digital adjustment
Digital adjustment of hook, presser foot, and thread trimmer (up/down separate drive)
Shorter adjustment time. Operation panel settings greatly reduce the "time spent on making fine adjustments with a tool".
The machine adjustment section is quantified to simplify adjustments. The quantified settings make it possible to reproduce machine adjustment sections that were previously not possible.
The finely honed sense of skilled workers can be digitally reproduced as necessary. Sections that required the finely honed sense of a skilled worker can now be adjusted simply by setting values in the operation panel.
* With the PLK-J2516-YU/J2516R-YU, only the presser foot can be 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 all have an open/close window on the sliding plate so that the bobbin can be easily exchanged. This greatly reduces the operator's work.
* Excludes PLK-J2516-YU/J2516R-YU
Glass epoxy sliding plate
The glass epoxy sliding plate is not contaminated as easily as the conventional stainless steel plate, and helps to prevent rust.
Spray-type digital oiling
Oiling of the hook and upper shaft is digitally controlled so only a minimal amount of oil is needed. This function prevents oil leaks.
