SIRUBA 747KT-514M-3-24/CT/DKKH1-0 2-Needle 4-Thread Direct Drive Top Feed Overlock Industrial Sewing Machine – Complete Setup, Table & Stand Included

The SIRUBA 747KT-514M-3-24/CT/DKKH1-0 is a high-speed 2-needle 4-thread top feed overlock from SIRUBA's 700KT top feed series, delivered with SIRUBA's own DKK direct drive servo motor kit and the CT flat-suction thread chain cutter. The 700KT adds a brand-new independent-drive top feed mechanism to the 700K platform: an upper feed dog with its own drive that grips and moves the top ply together with the bottom ply, with a stroke adjustable from 1 to 6 mm.

That positive top feed is what keeps plies from shifting on slippery, bulky or multi-layer seams and lets the operator match plaids and ease one layer into another, while the bottom differential feed (1:0.7 – 1:2, lever adjusted) stretches or gathers knits. This subclass runs 2 mm needle gauge and 4 mm overedge width with a 3-row feed dog, 5 mm presser foot lift, DC×27 #11 needles and up to 6,500 stitches per minute, with push-button stitch length and fully automatic lubrication.

The DKKH1-0 kit mounts a SIRUBA H-series direct drive servo motor to the head — no belt, faster response and lower consumption than an external clutch or belt motor — and the CT device pulls the thread chain into a trimmer tube by suction (suction motor or air compressor) so every seam ends clean without hand cutting. It ships assembled on a fully submerged industrial table with stand.

What's Included

• SIRUBA 747KT-514M-3-24/CT/DKKH1-0 2-needle 4-thread top feed overlock machine head (Ships Assembled)
• SIRUBA DKK H-series direct drive servo motor kit (DKKH1-0), mounted to the machine head
• CT flat-suction thread chain cutter device
• Fully submerged industrial sewing table
• Industrial stand with motor mount
• Presser foot and standard accessories kit (tools, oil can, thread stand)
• DC×27 needles and thread guides
• Instruction manual

Key Features

• Independent-drive top feed, 1 – 6 mm stroke — positive feeding of the top ply; no shifting, puckering or "walking" on slippery or multi-layer seams
• 2-needle 4-thread overlock (sewing type 514) — elastic, secure seam with safety overedge for knits and light wovens
• 2 mm gauge, 4 mm overedge, 5 mm presser foot lift, DC×27 #11 — the standard medium-weight configuration
• SIRUBA DKK H-series direct drive servo motor (DKKH1-0) — motor coupled to the head: no belt loss, immediate response, quieter and more efficient than a belt-driven setup
• CT flat-suction thread chain cutter — the thread chain is drawn into the trimmer tube by suction motor or air compressor and cut automatically at seam end
• 6,500 SPM maximum speed — top feed without giving up 700K-class output
• Differential feed 1:0.7 – 1:2, lever adjusted, for stretching or gathering knits
• Push-button stitch length adjustment up to 3.2 mm
• Fully automatic lubrication with silicone needle cooling for sustained high-speed running
• DC×27 needle system — the widely stocked industrial overlock needle

Ideal For

• Side seams and shoulder seams on T-shirts, polos and knitwear where plies tend to shift
• Slippery synthetics, fleece and multi-layer seams in sportswear and activewear
• Plaid and stripe matching in woven shirts and pajamas
• Underwear, sleepwear and lightweight stretch garments
• High-volume garment lines that want direct drive efficiency and automatic chain cutting
• Uniform and workwear production
