Pegasus FW803 Feed-up-the-arm Interlock (Flatlock) Machine

Also listed as FW803, FW803-V, FW803-VX356, FW 803, FW-V and FW803 flatlock

A feed-up-the-arm interlock machine with a 420 mm long arm, for covering the overlocked seams that run along sweatpants legs and other long tubes. The tube goes over the arm and the seam feeds up it, so the garment is covered after it is closed.

The Pegasus FW803 in 30 seconds

What it is

Pegasus's long-arm machine in the FW-V series: a feed-up-the-arm, cylinder bed interlock for covering, with 3 or 4 needles, 5 or 6 threads, a 420 mm arm, a thread trimmer and a presser foot lift.

Who it's for

Sweatpants, tracksuit, sweatshirt and fleece factories in the UAE, the GCC and Africa that cover long overlocked seams on legs and sleeves.

Why this model

Choose it for long seams on closed tubes. The FW703 in the same series has a 255 mm arm for sleeves at 4,000 sti/min; for hems that run round a tube, a cylinder bed like the W664P is the machine.

Setting up a knitwear line with the FW803

Most interlock machines we supply go onto T-shirt, sportswear and underwear lines next to the overlocks. We quote by the line and stay with you after the machines are running.

What the FW803 does on a factory floor

Pegasus FW803 long-arm feed-up-the-arm interlock machine, 420 mm arm marked by Pegasus

420 mm long arm

Long seams on closed tubes

The FW803 is the long-arm model of the FW-V series: 420 mm, against 255 mm on the FW703. Pegasus shows it covering the leg seams of sweatpants.

On the factory floorThe leg goes over the 420 mm arm, so the operator covers the leg seam of sweatpants after the leg is closed, without opening it.

Pegasus FW-V thread trimmer (UT): heel-pressed treadle mechanism under the FW803 cylinder bed

Thread trimmer (UT)

Heel-pressed thread cutting

Pegasus fits the UT thread trimmer to the FW803, electric or air operated. The operator cuts the threads by pressing the treadle with the heel; Pegasus states this improves operator efficiency for higher production.

On the factory floorThe UT cuts the threads when the operator presses the treadle with the heel, so each leg or sleeve seam ends without reaching for scissors.

Compact motor and safety cover

Quick to install, covered at the handwheel

Pegasus fits the FW-V with a compact motor that it says installs out of the box, starts and stops smoothly and runs with less vibration and noise. A safety cover at the handwheel, shown open and closed in Pegasus's catalogue, keeps dust out and protects the operator.

On the factory floorThe compact motor installs out of the box and a cover guards the handwheel, so the machine is quick to put on a line and safer to work at.

  • Presser foot lift (PL)

    Pressing the treadle with the heel raises the presser foot, which Pegasus says reduces operator fatigue.

  • Crank and lever

    Stitch length is set with a crank and the differential feed with a lever.

  • 4-needle, 6-thread build

    The FW803-V is also built with 4 needles and 6 threads, at the same 5.6-6.4 mm gauges.

Pegasus's FW-V series also includes the FW704 for attaching tape on T-shirts, with an optional air tape cutter (TK). The smaller FW-S series (FW603S) covers small goods at 4,500 sti/min.

Questions about the Pegasus FW803

Anything else, ask us on WhatsApp. We usually reply within one working day.

Ask on WhatsApp

Is the Pegasus FW803 the same as the FW803-VX356 on our quotation?

Yes. FW803-V is Pegasus's subclass name in the FW-V series, and X356 follows Pegasus's ordering code for 3 needles at a 5.6 mm gauge. Pegasus ended production of its earlier FW series in April 2025 and now lists the FW-V series (FW803, FW703, FW704) and the smaller FW-S series as its feed-up-the-arm interlock machines.

What is the price of the Pegasus FW803 in the UAE, Saudi Arabia, Nigeria, Ghana or Kenya?

We quote it delivered to your city, so the price depends on the subclass, the needle gauge, the devices (thread trimmer, presser foot lift), the table and stand, the quantity and the shipping. For a factory line we quote all the machines together. Send your city and quantity on WhatsApp or through the enquiry form and we reply with the price and delivery time, usually within one working day.

What is a feed-up-the-arm machine for?

For seams that run along a tube after it is closed. The tube goes over the arm and the seam feeds up it, so the operator covers sweatpants leg seams and sleeve seams without opening the garment. A cylinder bed machine like the W664P sews round a tube instead: body hems, sleeve hems and cuffs. For narrow children's tubes, the W264P small cylinder bed. Many buyers say feed-off-the-arm; Pegasus uses that name for its FS and FV series and calls the FW machines feed-up-the-arm.

Can you equip a whole line, not just this machine?

Yes. Tell us what you make and your daily output target. We recommend the machine mix for the line, from lockstitch and overlock to interlock and special machines, and can visit your factory for an assessment first.

FW803 or FW703: which do I need?

Both are FW-V feed-up-the-arm covering machines with the same needles, threads and gauges. The FW803 has the 420 mm long arm for long seams such as sweatpants legs and runs at up to 3,500 sti/min. The FW703 has the 255 mm standard arm, which Pegasus shows on sleeves, and runs at up to 4,000 sti/min.

Is the FW803 suited to heavy fleece?

Pegasus lists the FW803-V for heavy fabric and for covering overlock seams folded over. It runs 3 needles with 5 threads or 4 needles with 6 threads, at a 5.6, 6.0 or 6.4 mm gauge. Send us a sample garment and we confirm the gauge and set-up before you order.

Is the FW803 the same as the FW603S? (also see FW603, FW603S, FW-S)

No, they are different machines. The FW603S is the smaller feed-up-the-arm interlock in Pegasus's FW-S series; the older FW603 (FW603FB, FW603GB) was in Pegasus's earlier FW series. Pegasus builds the FW603S with 3 needles and 5 threads at 5.6 mm, up to 4,500 sti/min, with a slender bed for covering small goods: the -F flattens overlock seams on medium to heavy sweatwear and training wear, the -G folds them over on light to medium T-shirts and sportswear. Choose the FW803 for long seams on heavy fabric, and ask us about the FW603S for smaller parts.

Can you supply the parts book and genuine parts for the Pegasus FW803?

Yes. Pegasus publishes a parts list for each series, and we quote genuine Pegasus parts by part number. Send us the full model code from the machine's plate, or a photo, on WhatsApp and we will find the part. Our technicians also answer setting and threading questions.

Do you deliver, install and train our operators?

Yes. We deliver across the UAE, the GCC and Africa, to cities such as Riyadh, Lagos, Accra and Nairobi, install every machine at your factory and train your operators and mechanics. After that we support you with genuine spare parts and annual maintenance contracts.

Can I see the FW803 before I buy?

Book a meeting at our showroom in Industrial Area 4, Sharjah. Bring your fabric and a sample garment and we go through the subclass, gauge and devices with you. Tell us the model when you book, so we can say what we can show you on the day.
