Supreme CSM-1790 Electronic Lockstitch Buttonhole

Supreme's established quality is achieved with simplified functions

Higher productivity

This sewing machine achieves higher productivity with its improved capabilities , quick acceleration at the beginning of sewing and quick deceleration at the end of sewing, increased thread trimming speed and the auto-lifter performance.

Easy to use Operation panel

Setting of functions such as the pattern number and the needle thread tension can be entered through the operation panel with ease. All characteristics of the buttonhole such as length, number of stitches, cutting space, tension can be set from the panel.

The operation panel is provided as standard with a USB port. This means that the sewing machine data management and software updating can be carried out with ease by means of the USB port.

Multiple-times knife dropping

Thanks to Supreme's unique multiple-times knife dropping function, the knife replacement is no longer required even when the buttonholing size is changed, such as In the case of small-lot production.

The number of times to drop the buttonhole knife are automatically set according to the buttonholing size.

Easy changeover of sewing settings

Changeover between purl stitching and whip stitching and between single stitching and double stitching can be carried out with ease.

Basting stitch on stretch materials

The basting stitch is effective on elastic materials such as knits.

Basting stitch : Since the needle thread is tucked in without fail, it will never jut out of the

buttonhole seams. Basting stitch can be sewn by nine rounds.

Main functions driven electrically

Electrically-driven mechanisms are used for the work clamp foot lifter, needle and bobbin thread trimmers, work clamp foot pressure regulator, buttonhole knife and thread tension controllers, thereby ensuring stable sewing that produces beautiful seams with less operating noise.

Active tension
(electronic thread tension control mechanism)

The needle thread tension can be separately set for the parallel section and bartacking section of the buttonhole seam according to various sewing conditions (thread, material, sewing speed, etc.) given, and those setting data can be stored in memory.

The needle thread tension can be changed over at the parallel and bartacking section of the buttonhole seam without fail, thereby producing beautifully-finished buttonhole stitch shape.

The needle thread tension to be employed at the beginning and end of sewing can be set individually. This helps prevent slip-off of the thread at the beginning of sewing and unravel of the finished seam.
