Frequently asked

Does it arrive assembled?

Yes — we assemble, calibrate and test-stitch it in Miami before shipping. To protect the machine during freight, the head ships detached from the table; remounting takes minutes and we can walk you through it by phone.

Can I finance it?

Yes. You can split your purchase into monthly payments with Affirm (checking your rate takes seconds and won't affect your credit score), and Synchrony offers special financing on qualifying purchases (subject to credit approval). See your options on the financing page.

Do you ship to Alaska, Hawaii or Puerto Rico?

Puerto Rico: yes. Freight is $150, and it's free on orders of $3,000 or more.
Alaska and Hawaii: parts and accessories ship there fine — USPS or UPS rates are calculated at checkout. But an industrial machine travels on a pallet by freight, and those two states can't be quoted automatically: get in touch before you order and we'll give you a firm price. +1 (954) 681-3894 or contact@suprasewing.com.

Warranty & support?

Yes — on top of the manufacturer's warranty, Supra Sewing backs your machine with our own coverage: 90 days on mechanical defects and 12 months on electrical & electronic parts (18 months on Speedway machines), serviced by our in-house techs in Miami, FL. Support in English & Spanish: +1 (954) 681-3894 or WhatsApp.

Expanded Description:

The Overlock Jack C7-4-M03/333 is revolutionizing the sewing industry as the first overlock machine equipped with artificial intelligence. This advanced 4-thread overlocker offers unparalleled flexibility, allowing users to choose from three operating modes:

  1. Manual Mode: Full control with the foot pedal for traditional sewing.

  3. Automatic Mode: The machine operates entirely through photocells for a hands-free experience.

Key Features:

  • Full Speed Feeding System: Real-time sensing of fabric position changes ensures optimal coordination between pressing force and feeding force, allowing for seamless operation over various fabric types—thick, thin, elastic, or rigid—without slowing down.
  • Presser Foot Transformer: Utilizes intelligent perception to adjust pressure in real time, detecting changes 32,000 times per second and leveraging a million data models for ultra-fast pressure response (0.00006 microseconds).
  • Smart Rhino Feeding: Features intelligent matching and precise feeding with 9.2Nm of super torque, ensuring accurate feeding at every degree of rotation for consistent results.

With these advanced capabilities, the Overlock Jack C7-4-M03/333 increases work efficiency by over 10%, making it an essential tool for both professional and home sewing enthusiasts. Elevate your sewing experience with this cutting-edge overlocker!
