J Series [Electronically Controlled Pattern Sewing Machines]

• 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 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.

• 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.

• Shorten the adjustment time for stitching corners, start of stitching and end of stitching. Times can be finely adjusted easily in the operation panel, so anyone can perform intuitive adjustments.
  The settings can be easily and finely adjusted according to the corners and number of stitches for each sewing product.
  The needle drop position (back or forth) can be easily adjusted.
• Even if a problem occurs at the corner during high-speed stitching, it can be easily adjusted.
  Productivity is improved as there is no need to drop the speed to create a neat corner.

* Supported by PLK-J2516-YU/J2516R-YU only

• 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.

• 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

• 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, use of this function enables the time and effort necessary for such 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.
