MO-6900J Series
Variable Top-feed, Overlock / Safety Stitch Machine for Extra Heavy-weight Materials
Description
The MO-6900J Series comes with a newly-developed feed mechanism that moves the top and bottom feeds separately. With its improved feeding capacity and stronger cloth-biting force, the feed mechanism prevents uneven material feed when sewing extra heavy-weight materials. |
