The stay button (counter button) sewing capability is a vital addition to the impressive application range of the AMB-289.

Sewing methods and sewing shapes can be easily reset on the operation panel.

In combination with the independent-drive needle-throwing method, the adoption of the Y-feed on the body side and X-Y feed on the button-sewing side enables the AMB-289 to sew patterns with variable numbers of buttonholes (such as four-holed front buttons and two-holed stay buttons).

The sewing speed has been enhanced to dramatically increase productivity.

As compared with manual button sewing, the AMB-289 achieves productivity as high as 5 times.

The machine sews buttons on a double-breast suit, a garment that requires the sewing of different types of buttons, in a continuous manner.

Cycle sewing data can be set/edited with the sewing item graphically displayed on the operation panel (the number of buttons, button sewing locations, and sewing order of buttons).

The button loader can feed two types of buttons in a single sewing cycle.

The operation panel is a touch-sensitive type LCD. The clear graphical displays make it much easier for the operator to set or modify sewing data.

A CompactFlash™ card can be used to store and transfer sewing data. This makes it possible for sewing machines at one or more factories to share data. In addition to the CompactFlash TM, the machine is provided as standard with a USB connector. As a result, the use of a USB flash drive or card reader enables the storage and transmission of sewing data by means of various kinds of media (such as a floppy disk, SmartMedia, CompactFlash and SD card) to enable sewing using the same sewing data among sewing machines in a plant or among subcontract plants.

The AMB-289 finishes four-holed buttons with a hand-stitched appearance (V-shape stitching) by fixing the tucking position at a preset location. This results in the sewing of a neat seam on the wrong side of the garment and neck-wrap knots at a single location. Seam quality is further enhanced as a result.

The neck-wrap data can be finely adjusted via the entry screen of the operation panel to enhance the sewing quality. The distribution of neck wraps on the upper and lower parts of the button neck, a crucial point in determining the quality of neck-wrapping, can be adjusted to prevent buttons and button necks from becoming unstable and tilting.

The neck-wrapping height can be adjusted by up to 10mm.

The exclusive active tension system for AMB289 further improves responsiveness and allows delicate tension setting when the user changes fabrics.

Thread tensions for button sewing and neck wrapping can be separately set on the operation panel.

The machine stores sewing conditions in memory on a pattern-by-pattern basis. Required sewing conditions can be exactly reproduced for every pattern.

The remaining length of needle thread can be adjusted according to the type of material or thread to be used. It effectively prevents thread from slipping off the material at the start of sewing.

The AMB-289 does not require the use of exclusive thread intended for button sewing. General-purpose cotton threads and spun threads are both applicable, depending on the type of material.
A full range of thread counts from 500~170dtex (#60~#30CA) can be applied. This ensures use for diverse processes.

The thread-trimming position is set to reduce the remaining length of thread on the material to a minimum.

The machine incorporates a thread-fray prevention function that ensures the tying of strong and reliable knots at the last stitch.

The number of stay stitches, which increases strength of button sewing stitches, can be set on the operation panel within the range of 0 and 3 stitches.

The tucking depth is increased to 5mm to ensure a consistent tucking depth in soft materials such as knits.

The feed accuracies are high as 0.05mm (some points are 0.1mm). This promises an accurate needle entry position and tucking depth.

Dramatically reduced oil stains
As the machine requires no lubrication, oil spatters and all other lubrication-related troubles are eliminated. Sewn garments have dramatically fewer oil stains as a result.
* Periodical greasing is required for some of the mechanical structures.

Dramatically reduced vibration and noise
The adoption of the needle-throwing mechanism dramatically reduces the vibration and noise usually produced during the neck-wrapping procedure.

The machine is provided as standard with a button loader
The machine is provided as standard with a button feeder that lets the operator place the next buttons to be sewn during overlapping-style work.
The button-delivery position between the button loader and button chuck can be easily adjusted on the operation panel. No tools are required.

LED now adopted
The AMB-289 is provided as standard with an LED-type handy light and marking light. The sewing area is now brighter and more viewable than it would be under the incandescent light of a conventional machine. LED light also offer the advantage of a longer service life. The machine is optionally provided with a marking light for sewing flat buttons directly to cloth.

Convenient hand pulley
The hand pulley is mounted on the top of head. This makes it easy to check the needle entry point.

The button loader gauge for the conventional model can also be used with the AMB-289
The set pins and four-holed and two-holed button carriers used with the AMB-189NR (the conventional model provided with a button loader) can also be used with the AMB-289.
* The AMB-289 requires dedicated set pins for shank buttons, marble buttons, and metallic buttons (optional).

Safety design
The safety-first design makes it impossible to start the machine without buttons set on the button chuck.
If the machine head tilts while the power ON, the safety switch automatically shuts down the machine even when the pedal or knee switch is pressed.
