The Juki MF-7900D-U11 is an industrial cylinder-bed machine for two- or three-needle top and bottom covering stitch. The frame is not lubricated (dry-frame design) to reduce oil stains on the fabric; the rest of the machine is oiled automatically. It takes UY128GAS needles from #9 to #12S, and the distance between the needles can be selected from five sizes. It is the basic version for hemming T-shirt sleeves and hems and for covering sportswear and knitwear.
