Juki DLN-6390S Industrial Single-Needle High-Speed Cylinder-Bed Needle-Feed Lockstitch Hemming Machine Complete Unit with Table and Servo Motor

This specialized cylinder-bed machine is engineered specifically for hemming heavy-weight fabrics like denim, work uniforms, and casual pants in high-volume production environments. The narrow cylinder-bed design allows operators to easily access tubular garment sections such as pant legs, while the integrated binder automatically folds the hem edge during stitching for efficient one-pass operation. Advanced roller feed technology drives material from both top and bottom to prevent layer shifting and puckering on thick, multi-layer constructions. The machine features a large-capacity 1.7-fold hook that reduces bobbin changes and handles heavier thread weights, plus a forced circulation lubrication system that minimizes maintenance requirements during extended production runs.

MACHINE FEATURES:

  • DLN-6390S: A knee lifter is supplied with the machine.
  • Narrow-Profile Cylinder Bed for Tubular Garment Access: The cylinder-bed geometry allows the machine to reach inside leg openings and other closed tubular sections. This turns bottom hemming on jeans or heavy workpants into a simple, efficient operation.
  • Integrated Binder — Fold and Stitch in One Pass: The binder folds the hem edge as the material feeds through the machine, combining folding and stitching into a single cycle. Binder position is adjustable both longitudinally and laterally for precise hem alignment. On the
  • Top-and-Bottom Roller Feed with 35 mm Needle Bar Stroke: The roller feed system drives all material layers at a consistent rate from both above and below, eliminating the layer slip that causes uneven hems and puckering on heavy denim and multi-panel sections. The
  • 1.7-Fold Capacity Hook: The exclusive large-capacity hook carries significantly more thread than a standard hook, reducing bobbin change frequency on long runs and handling heavier thread weights reliably — critical for sustained hemming operations on heavy denim and thick workwear fabrics.
  • Forced Circulation Lubrication with Full Oil Leakage Prevention: The lubrication system uses a forced circulation mechanism designed for reliable oiling across all critical components, including the hook. The frame and cylinder-bed sections are equipped with a dedicated circulation feature to prevent oil leakage, and a gasket fitted inside the frame seals the needle bar. The needle bar sliding mechanism is newly designed for high durability and is free of play. Together these reduce maintenance stops and protect mechanical consistency across long production runs.
  • Low Presser Foot Pressure Sewing: The machine maintains material control at low presser foot pressure without allowing the material to flap, producing pucker-free hems even on sections where excessive pressure would distort the fabric or hem fold.
  • Dial-Adjustable Feed Amount with Interchangeable Pitch Gears: The needle feed amount is adjustable via a scale dial, allowing operators to fine-tune feed for different material and thread combinations. Stitch length is configurable across seven settings from

Machine Warranty Protection

Besides any applicable warranties provided by the Original Manufacturer, Jacksew offers a standalone 90-day limited warranty on defects in materials and workmanship.

  • This warranty covers all the machine parts and labor but any shipping costs must be covered by the customer

  • Only applies under normal sewing conditions as prescribed for the machine

  • Consumable items are not covered (needles, bobbins, bobbin cases, springs, oil, and belts)

  • This warranty does not cover improper use or abuse under heavy use of machines

  • This warranty does not cover flood, fire, or other acts of nature

If there are any warranty issues that arise, we ask that you contact us immediately and let us know the details. In most cases, we can guide you with getting your machine in good sewing condition via phone, text or video chat.

If you need any parts that need to be replaced, we stock the majority of parts for immediate shipment. Some parts not in stock may have to be ordered from the manufacturer and may take 1 to 2 weeks for arrival.

If there is a critical issue that needs to be addressed and is out of scope of minor adjustments or repairs, we will ask you to send us the machine to our shop so we can have it repaired and have it back to good sewing condition. In most cases, we will only need the machine head shipped to us. Shipping charges - both inbound and outbound - are the responsibility of the customer.

Warranty issues do not arise frequently because of our commitment to assemble, test and verify each machine we ship out to our customers. We will never send you a machine directly from the manufacturer in boxes without knowing that the machine will be ready to operate upon arrival.

DISCLAIMER: DUE TO THE HEAVY WEIGHT AND SHIPPING METHODS USED FOR INDUSTRIAL MACHINES THEY MAY EXPERIENCE MARRING AND SCRATCHES DURING SHIPPING. THIS WILL NOT AFFECT THE OPERATION OF THE MACHINE.

ANY DAMAGE OCCURRING DURING SHIPPING MUST BE CLAIMED TO THE FREIGHT CARRIER IMMEDIATELY. UPON REQUEST, JACKSEW WILL PROVIDE ASSISTANCE IN FILING A CLAIM ON YOUR BEHALF DURING SUCH AN EVENT. PLEASE NOTIFY US WITHIN 5 BUSINESS DAYS.
