• The machine-head-turning mechanism helps achieve high-quality seams uniformly in every sewing direction

  JUKl's unique synchronization technology controls the machine head, hook and feed mechanism, thereby creating the most favorable seams.
  In case of continuous circumference sewing, the sewing machine constantly detects the direction of sewing. As a result, consistent-quality seams are produced regardless of the direction of sewing.

  

• With its sewing area of "1,000 mm × 600 mm" the AMS-251 is best suited to the sewing of decorative stitches and large-size products

  The sewing machine is ideally suited to the sewing of decorative stitches on car seats, luxury bags and school bags, but also to the sewing of large-sized products with zero design tolerance for irregular stitches. In addition, the sewing machine can be used for sewing two or more pieces of small products at a time.

  

• Perforation Camera System (optional)

  Thanks to JUKl's original image recognition technology, this sewing machine enables sewing of hard-to-sew perforated materials as desired and produces beautifully-finished seams.

  

• Machine head turning Slip ring system*¹

  Slip ring system has been adopted to the new machine-head turning mechanism. As a result, limitless turning of the machine head is enabled to allow the sewing machine to sew complicated patterns continuously.

  *1 Rotating connector that is able to transmit power and electric signals from the stationary body to the rotating body

  

• Machine head turning Cutting point needle

  The cutting point needle can be used regardless of the sewing direction since the sewing machine constantly faces the sewing direction at its front.

  

• Machine head lifting function

  Since thick materials, clamps, palettes with protrusions can be used, design will be expanded.

  

• Multi-axis control technology

  The multi-axis control technology used by JUKI are applied to simultaneously control six axes*².

  *2 Machine-head turning, Hook turning, Main shaft, Hook driving shaft (hook), X-axis feed, Y-axis feed

  

• Horizontal-axis, 3 fold-capacity rotary hook

  Adoption of the 3 fold-capacity hook helps reduce the frequency of bobbin replacement even when thick thread is used, thereby supporting sewing of large products.

  

• Operation

  The IP420 for the existing AMS Series models has been adopted for the new AMS model. In addition, the existing sewing pattern input software "PM1" is also applicable.

  

• Safety cover

  Opening and closing sensor is mounted to the turning-head cover and turning-hook cover to prevent the machine from starting when the cover(s) is opened and to automatically stop the machine if the cover(s) is opened while the machine is in operation.

  

• Start button

  A 2-handed start button has been adopted for safe, accurate start up. In addition, unintentional start up of the machine is prevented.

  

• Bobbin replacement cove

  Bobbin can be changed easily by opening the accessible cover without requiring the operator to reach under the machine to change the bobbin.
