JUKI MH-484U Single Needle Chainstitch Differential Feed Industrial Sewing Machine

Juki MH-484U Single Needle Double Chainstitch Machine with Differential Feed

The Juki MH-484U is a versatile single-needle, double chainstitch machine designed to deliver exceptional performance on elastic and lightweight materials. Its advanced differential feed system ensures beautiful, consistent seams, making it ideal for a wide range of sewing applications. With a user-friendly lever operation, you can effortlessly switch between stretch stitching and shirr stitching, adapting to various fabric requirements and sewing tasks.

Key Features:

1. Effortless Stitch Adjustment: Switch seamlessly between stretch and shirr stitching modes with a simple lever operation. This lever also allows for easy adjustment of the differential feed ratio, accommodating diverse sewing needs.

2. Versatile Gathering and Shirring: Optional attachments such as the gathering attachment (S060), intermittent gathering attachment (S061), and partial shirring device (PF5) enable consistent gathering and partial shirring. The machine also offers replaceable gauges and a urethane feed dog tailored for lightweight materials.

3. Enhanced Sewing Mechanisms: The MH-484U features a thread spreading mechanism and adjustable needle guard to prevent stitch skipping. Additional mechanisms include a thread clamp, tension release, and needle thread draw-out, ensuring uniform thread length after trimming and preventing needle thread slip-off.

4. Safety and Reverse Stitching: Easily switch between safety stitching (condensation stitching) and reverse feed stitching (back-tacking) with a quick adjustment of the reverse feed lever. Both methods offer robust options for secure seams.

5. Superior Seam Quality: Equipped with a sliding presser foot and silicone oil lubricating unit, the machine minimizes stitch skipping and puckering. The silicone oil unit also prevents needle overheating, allowing for smooth use of foundation yarn or synthetic thread, ensuring consistently high-quality seams for light to medium-weight fabrics.
