| This mechanism prevents problems, such as twist of fabric, uneven material feed, skew of grain and stitch gathering on multi-layered sections of material, which are likely to occur when sewing elastic materials, thereby achieving stable seam quality. |
 |
| Digital setting of the top feed mechanism can be carried out with jog dial with control panel.
(Top feed amount can be adjusted and stored directly in memory.) |
 |
| Digital setting of the top feed mechanism enables easy adjustment of sewing even when the product to be sewn is changed, thereby reducing the setup time. |
