Affiliate disclosure: product links on this page go to Amazon, or to the maker's own store for brands that sell only direct. As an Amazon Associate we earn from qualifying purchases, at no extra cost to you; a link to a maker's store earns us nothing. No retailer or brand sees our picks before they are published or has any say in them. How we choose.

The Janome CoverPro 2000CPX is our pick for most sellers: a free arm for sleeves and cuffs, chain, cover and triple cover stitches, the widest differential feed range here (0.5 to 2.25) and an LED light, with a Janome MSRP of $1,099. The Brother 2340CV sews the same three kinds of hem for a Brother list price of $579.99, without a free arm in its spec list.

A coverstitch machine sews the hem you see on ready-to-wear T-shirts, leggings and activewear: two or three rows of straight stitching on top, with a looper thread underneath that lets the hem stretch. A serger cannot sew it, which is why knitwear sellers often own both. Every figure below is from the maker's own page.

Best overall

Janome CoverPro 2000CPX

Free arm, chain, cover and triple cover stitches, Tension Level Control and an LED light, with a Janome MSRP of $1,099.

Cover stitches
Chain, 2-needle cover, 3-needle triple cover
Max speed
1,000 spm
Widths
3 mm (narrow) or 6 mm
Free arm
Yes

Pros

  • Free arm configuration for hemming sleeves, cuffs and leg openings
  • Differential feed ratio from 0.5 to 2.25, the widest range here, per Janome
  • Extra large 4 by 5.5 inch bed space and a vertical needle drop
  • Tension Level Control, LED light, four cones of thread and a dust cover included

Cons

  • Sold through authorized Janome dealers; on Amazon, through third-party sellers
  • Tops out at 1,000 stitches per minute, slower than the Juki and Brother 2340CV

Janome describes the CoverPro 2000CPX as a cross between an industrial cover hem machine and a home machine: a long arm, heavy-duty cover hem machine that looks and runs like a sewing machine. It sews a 1-needle, 2-thread chain stitch, a 2-needle, 3-thread cover stitch at 3 mm (narrow) or 6 mm (standard) and a 3-needle, 4-thread triple cover stitch 6 mm wide. Stitch length runs from 1 to 4 mm and speed up to 1,000 stitches per minute.

The features that matter for production hemming are the free arm, the 0.5 to 2.25 differential feed range for keeping knit hems flat, adjustable foot pressure with guide lines and a 4 by 5.5 inch bed. Janome also sells the CoverPro 1000CPX at an MSRP of $999, with the same stitches and its Seam Tightening System; Janome's 2000CPX page adds Tension Level Control and an LED light, which the 1000CPX page does not list.

Best value

Brother 2340CV Coverstitch Machine

Tri-cover, wide and narrow cover stitches and chain stitch for a Brother list price of $579.99, sold by Amazon itself.

Cover stitches
Chain, narrow, wide, tri-cover
Max speed
1,100 spm
Widths
3 to 6 mm
Free arm
Not in Brother's spec list

Pros

  • Three needles and one looper for tri-cover, wide and narrow cover stitches and chain stitch
  • Lay-in threading, color-coded guides and a fast looper threading system, per Brother
  • Stitch length 2 to 4 mm and adjustable presser foot pressure
  • 1/5/25 year limited warranty, per Brother

Cons

  • No free arm in Brother's spec list, so sleeves and cuffs are harder to hem in the round
  • Bulb lighting rather than LED, per Brother's spec table

Brother's 2340CV is a dedicated coverstitch machine with three needles and one looper. It sews a tri-cover stitch, wide and narrow cover stitches from 3 to 6 mm and chain stitch, at up to 1,100 stitches per minute, with stitch length from 2 to 4 mm set by dial and a slide lever for differential feed. The Amazon listing gives the differential feed as 0.7 to 2.0 (per the Amazon listing). Threading is lay-in and color-coded, with what Brother calls a fast and easy looper threading system.

For the price of many sergers, it adds the hem that a serger cannot sew. The trade-off against the Janome is the lack of a listed free arm, which matters if you hem a lot of small tubes such as kids' sleeves. Amazon also lists the 2340CV in a bundle with Brother's 1034D serger, which is the pairing in our best serger guide.

Best for thick layers

Juki MCS-1500 Cover and Chain Stitch Machine

1,350 stitches per minute, a two-height presser foot lift for thick fabric and Juki's disengaging lower looper threader.

Cover stitches
Chain, 3- and 4-thread cover
Max speed
1,350 spm
Widths
2.5 or 5 mm
Free arm
Not on Juki's page

Pros

  • Fastest machine here at up to 1,350 stitches per minute, per Juki
  • Presser foot lifts to 8 mm or 10 mm for thick layers, and the front of the foot rises higher for easier fabric insertion
  • Lower looper threader disengages, then snaps back into place, per Juki
  • Extension plate with seam guidelines and an exterior thread cutter

Cons

  • JUKI suggested retail price of $1,239
  • On Amazon it comes from third-party sellers, often in short supply
  • Juki's page does not mention a free arm

Juki sells the MCS-1500 as a specialized chainstitch and coverstitch machine. It sews 3-thread and 4-thread coverstitch with a choice of 2.5 mm or 5 mm width, plus chainstitch, at up to 1,350 stitches per minute, with a 4 mm maximum stitch length. Its lower looper threader disengages so you can slide the thread in, then snaps back into place.

The foot is the reason to pick it for heavier knits such as sweatshirt fleece: Juki says it opens to 8 mm or 10 mm for thick layers, and the front of the foot lifts higher than the back for easier fabric insertion. It also has adjustable presser foot pressure, a seam-guide extension plate and a thread cutter on the outside of the machine. The machine weighs 15.5 lb, per Juki.

Best for double-sided cover stitch

Brother CV3550 Coverstitch Machine

Adds a cover spreader for double-sided versions of each cover stitch, with a free arm and an LED-lit workspace.

Cover stitches
Chain, narrow, wide, tri-cover, each also double-sided
Max speed
1,000 spm
Widths
Not on Brother's page
Free arm
Yes

Pros

  • Three needles, one lower looper and one cover spreader, per Brother
  • Double-sided tri-cover, wide cover and narrow cover stitches as well as the standard ones
  • Free arm "for easier sewing of necklines and cuffs", per Brother
  • Large, LED-lit 6.1 by 3.9 inch workspace and a built-in thread cutter

Cons

  • Not sold on Amazon (this link earns us nothing); Brother points buyers to dealers
  • Brother's page gives no price, stitch widths or included feet

The CV3550 adds what the 2340CV lacks: a cover spreader and a free arm. It has three needles, one lower looper and one cover spreader, which adds double-sided versions of its stitches: double-sided tri-cover, double-sided wide cover and double-sided narrow cover, alongside the standard tri-cover, wide and narrow cover stitches and narrow and standard chain stitching. It runs at up to 1,000 stitches per minute.

Brother lists a free arm for necklines and cuffs, a large 6.1 by 3.9 inch LED-lit workspace, a thread cutter, adjustable presser foot pressure and color-coded threading with easy looper and cover spreader threading. It carries Brother's 1/5/25 year limited warranty and is sold through dealers, so ask one for the current price and which feet come in the box.

What a coverstitch machine sews

A coverstitch machine does not trim the edge. It sews two or three parallel rows of needle stitches on the right side of the fabric while a looper below forms a chain of thread on the wrong side. That looper chain is what lets the hem stretch with a knit. Janome calls the result a cover hem; Brother describes its 2340CV's cover stitches as good for stretch fabrics, necklines and hems (per the Amazon listing).

Using Janome's terms, the three stitches you will see on every machine here are:

  • Chain stitch: one needle, two threads. A single row of straight stitching on top with a chain underneath.
  • Cover stitch: two needles, three threads. Two parallel rows, narrow (3 mm on the Janome) or standard (6 mm).
  • Triple cover stitch: three needles, four threads. Three parallel rows across a 6 mm width.

Brother's CV3550 adds a cover spreader, which gives double-sided versions of the cover stitches.

What to look for

A free arm

Sleeves, cuffs, leg openings and necklines are small tubes. A free arm lets you slide them over the bed and hem them in the round. Brother says the CV3550's free arm is for easier sewing of necklines and cuffs, and Janome lists a free arm on both of its CoverPro models. The Brother 2340CV and Juki MCS-1500 pages do not list one.

Differential feed

Knit hems can stretch into a wave or pucker. Differential feed corrects that, and the range sets how far you can push it: 0.5 to 2.25 on the Janome CoverPro models, 0.7 to 2.0 on the 2340CV per the Amazon listing. Bernina's serger tips give the general rule: toward the higher setting for fabric that stretches out of shape and toward the lower one for puckering.

Foot lift and pressure

Hems on sweatshirts and fleece stack several layers at side seams. Juki's MCS-1500 opens its foot to 8 mm or 10 mm, and every machine here has adjustable presser foot pressure.

Speed

The machines here run at 1,000 to 1,350 stitches per minute. On a hem that is a few feet long, speed matters less than the hem coming out right the first time.

A separate machine or a combination machine?

Some machines serge and coverstitch in one body. Juki's MO-735 is a 2/3/4/5 thread overlock with chainstitch and coverstitch, and Baby Lock's Triumph and Splendor are 8-thread overlock and coverstitch machines. A combination machine saves table space and one purchase. A separate coverstitch machine can stay set up for hems while the serger stays set up for seams, which saves changeover time when you sew in batches.

Frequently asked questions

Do I need a coverstitch machine if I have a serger?

For the stretchy two- or three-row hem on T-shirts and leggings, yes, unless your serger is a combination machine. A standard serger trims and overcasts edges but cannot sew a cover hem, which needs needles on top and a looper below with no knife.

What is a triple cover stitch?

Three parallel rows of needle stitching on top with a looper thread below. Janome sews it with three needles and four threads across a 6 mm width; Brother calls its version a tri-cover stitch.

Can a regular sewing machine sew a coverstitch?

Not a true one. A twin needle on a sewing machine gives two rows on top, but it has no looper underneath, so the back and the stretch differ from a cover hem. For a production run of knit hems, a coverstitch machine is the tool built for it.

What is the difference between the Janome CoverPro 1000CPX and 2000CPX?

Both sew the same chain, cover and triple cover stitches with a free arm and 0.5 to 2.25 differential feed. Janome's 2000CPX page adds Tension Level Control and an LED light, and its MSRP is $1,099 against $999 for the 1000CPX.

Why does a coverstitch machine need a free arm?

Sleeves, cuffs and necklines are small tubes. A free arm lets you hem them in the round instead of opening a seam to sew them flat. Brother says the CV3550's free arm is for easier sewing of necklines and cuffs.
