High-speed double chainstitch for seaming denim, workwear and heavy fabrics. The JUKI MH-481-5 is a High-Speed Double Chainstitch Machine built for industrial production. It offers a maximum sewing speed of 5,500rpm and a stitch length range of 1~4mm, with the full official JUKI specification listed below. As the official JUKI distributor in Egypt, Moussa Egypt supplies this machine with installation, operator training and full after-sales support.
The machine comes with a thread spreading mechanism and an adjustable needle guard to prevent stitch skipping. The thread clamp mechanism, tension release mechanism and needle thread draw-out mechanism enable the machine to leave thread of a uniform length after thread trimming, and prevent slip-off of the needle thread. All of these mechanisms contribute to upgraded sewing.
Safety stitching (condensation stitching) the perfect method of preventing loose stitches, or reverse feed stitching (back-tacking) can be alternated through the simple adjustment of the stopper of the reverse feed lever. Either sewing method can be used.
Provided with a sliding presser foot and a silicone oil lubricating unit as standard, stitch skipping and puckering are prevented. Furthermore, the silicone oil lubricating unit prevents the needle from overheating, and allows foundation yarn or synthetic thread to be used without breakage during sewing. These features assure beautifully finished seams with consistency for light- to medium-weight materials.
