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. Head Liftable 50 mm.

Multi-axis control technology

The multi-axis control technology used by JUKI is 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.


image image

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.


image image

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 cover

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


FAQ FAQ

ALL
QWhat is the intended use of the AMS-251?
ASince the AMS-251 produces consistent-quality seams regardless of the sewing direction, it is suitable for sewing decorative stitches on car seats and sewing bags, briefcases and air bags.
QWhile the sewing machine is performing sewing
of a material, is it possible to place other material on the sewing machine?
AYes. Since the AMS-251 adopts the cassette clamp, it is possible to preset two or more different materials by using two or more cassette clamps at a time.
QIs it necessary to input the number of revolutions of the sewing machine head as a piece of data on a sewing pattern?
ANo. The AMS-251 automatically calculates the appropriate sewing speed for the sewing pattern.
QIf the current sewing process requires a cutting point needle, is a cutting point needle also available for this machine?
AYes, it is available. By adopting the head rotation mechanism which always faces the sewing direction in front, the machine can sew leather or thick material with a cutting direction aligned with the sewing direction.
QCan I purchase parts from JUKI?
AYes. Check first the part number of the part you need on the "JUKI PARTS Website" page of the JUKI website.Then, contact the JUKI distributor near you to purchase the part you need.
QI am using the conventional model of the AMS-EN Series sewing machine. Is it possible to use the conventional pattern data also for the
AMS-251?
AYes. The pattern data for the conventional models of the AMS-EN Series is also applicable to the AMS-251. But the cassette clamps for the conventional models are not applicable used as it is.
QWhat are the required entrance dimensions to receive the AMS-251 at a location?
AAMS-251 dimensions shown in the catalog:
2,400 (W) x 1,800 (D) x 1,600 (H)
The aforementioned dimensions can be reduced (depth only) as shown below by removing the removable parts from the AMS-251.
2,400 (W) x 1,455 (D) x 1,600 (H)
(Unit: mm)
QWhat is the weight of the AMS-251?
AIt weighs 950 kg.
