JUKI MH-484-54U Advanced Feed Single Needle Double Chainstitch (UBT) Industrial Sewing Machine

Juki MH-484-54U High-Speed, Single Needle, Double Chainstitch Differential-Feed Machine with Automatic Thread Trimming

The Juki MH-484-54U is a versatile sewing machine designed to deliver beautifully finished seams in elastic and lightweight materials. With its automatic thread trimmer and adjustable differential feed, this machine adapts seamlessly to various sewing requirements, making it an ideal choice for diverse applications.

Versatile Sewing with Easy Adjustments Switching between different sewing methods is effortless with the simple operation of a lever. You can alternate between stretch stitching and shirr stitching or adjust the differential-feed ratio to suit your sewing needs. This flexibility allows for precision and customization in your stitching process.

Advanced Features for Specialized Sewing The MH-484-54U offers options for consistent gathering and partial shirring, thanks to available attachments like the gathering attachment (S060), intermittent gathering attachment (S061), and partial shirring device (PF5). Additionally, replaceable gauges and the urethane feed dog accommodate various applications, ensuring the machine’s adaptability to different materials and sewing processes.

Enhanced Sewing Performance Equipped with a thread spreading mechanism and an adjustable needle guard, this machine effectively prevents stitch skipping. The thread clamp mechanism, tension release mechanism, and needle thread draw-out mechanism ensure uniform thread length after trimming and prevent the needle thread from slipping off. These features collectively enhance the quality and reliability of your sewing.

Safety and Efficiency in Stitching The Juki MH-484-54U enables both safety stitching (condensation stitching) and reverse feed stitching (back-tacking) through the straightforward adjustment of the feed lever’s stopper. This ensures secure and reliable stitching methods tailored to your specific needs.

Consistent, High-Quality Seams With a sliding presser foot and a standard silicone oil lubricating unit, the machine prevents stitch skipping and puckering. The silicone oil unit also keeps the needle cool and prevents thread breakage, making it suitable for sewing with foundation yarn or synthetic thread. These attributes guarantee consistently high-quality seams for light to medium-weight materials.
