Overview

The 747D is a high-speed 4-thread overlock machine. It trims the fabric edge and overcasts it with a neat four-thread seam in one operation — the standard finish on t-shirts, sportswear and most woven garments.

On a production line it sits alongside a lockstitch machine: the lockstitch sews the main seams, the overlock finishes edges and joins stretch panels. If you produce knitwear, this is the first finishing machine to add.

For seams that take real stress — denim and heavy cotton — a 5-thread machine adds a safety stitch on top of the standard overlock.

Key Applications

  • T-shirts, polo shirts and knitwear — clean edge finishing on stretch fabric → Garment factory machines
  • Sportswear and activewear — pucker-free seams
  • Edge finishing on woven garments — one-pass trim and overcast

What’s Included

  • Machine head
  • Industrial table and stand
  • Servo or clutch motor
  • LED work light
  • Tool kit and manual

Delivered as a complete working unit — no extra parts needed to start production.

Frequently Asked Questions

What's the minimum order quantity?+

1 unit. Order 1–4 machines and we ship by express courier or LCL sea freight — a full container is optional, not a requirement.

Which voltage will I receive?+

Your machine ships configured for your country's mains supply — we confirm the exact voltage with you before shipping. Available options: 220V, 230V, 240V.

Can I get spare parts later?+

Yes — we keep common parts in stock and can include a spare parts pack with your order, so a worn part never stops your production.

Can it sew knits and stretch fabric?+

Yes — the differential feed prevents stretching and puckering on elastic fabrics.

What fabric can a 747 overlock machine sew?+

Light and medium knit and woven fabrics. For very thick denim seams, use a 5-thread machine.

Is 4-thread enough for general garment work?+

Yes — 4-thread is the industry standard for most woven and knit garments. Choose 5-thread when seams need extra strength.
