Jack C7-6-03-333 High Speed 6 Thread Overlock Machine Complete Unit with Table and Stand

This advanced 6-thread overlock machine represents a breakthrough in automated sewing technology, featuring JACK's revolutionary A.M.H. (Automatic Material Handling) system that uses artificial intelligence to continuously monitor fabric properties and make real-time adjustments. The AI system performs up to 32,000 corrections per second, automatically adjusting feeding force and presser foot pressure to deliver consistent stitch quality across any material type without requiring operator intervention or speed reduction. With three operating modes ranging from manual to fully hands-free automatic operation, this machine excels in high-volume production environments where mixed or variable-weight fabrics demand reliable performance. The intelligent design eliminates the common need to slow down for difficult materials, making it ideal for garment manufacturing, sportswear production, and technical textile applications where speed, consistency, and automation are essential.

MACHINE APPLICATIONS:

  • High-volume production overlocking on mixed or variable-weight fabrics where consistent stitch quality without operator adjustment is required
  • Operations requiring automated thread trimming, presser foot lift, and hands-free workflow
  • Garment manufacturing, sportswear, and technical textile production demanding speed and reliability across diverse materials

MACHINE FEATURES:

  • A.M.H. AI system adjusts feeding force and presser foot pressure up to 32,000 times per second — delivers consistent stitch quality across all fabric types without slowing down
  • Three operating modes: Manual (foot pedal), Semi-Automatic (auto thread trim and presser foot lift via photocells), and Automatic (fully hands-free operation)
  • Full Speed Feeding System — real-time fabric sensing maintains consistent feed force at full speed, eliminating the need to reduce pace on difficult materials
  • Presser Foot Transformer — intelligent pressure adjustment prevents compression damage on delicate fabrics and maintains even feed on heavyweight materials
  • 6-thread, 3-needle configuration with plain seam and safety stitch functions for high-strength, production-grade seaming
  • Maximum speed of 7,000 SPM for high-volume output
  • Complete setup with table and stand included — ready to install and run

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.
