Flat seamer introduction Flat seamer is a sewing method. Flat seam seams are generally 4-needle stitches. The seams (the part that is sewn together) on a flat seamer sewing machine are very similar to those on a flat three-needle sewing machine, but the back side of the seam (the part that is sewn together) does not bulge and the cross section is flat. Flat seam processing and mesh zones support all sports. The fabric I often use is polyester bare-ten. Because it is woven with ultra-fine threads, it has a beautiful silk-like luster and supple texture. Because it has stretch properties, it has a moderate fit and does not feel constricting, making it supple and comfortable to wear!

A flat seamer is a sewing machine that can sew flat surfaces, developed by the American Union Special Company in 1962 (around 1962). However, production has now ended, and we are now using products developed by domestic sewing machine manufacturers. It is called a flat seamer because it can sew two pieces of fabric together using four needles and six threads, creating a flat seam (SEAM). I am. Since it is a special sewing machine, it is also characterized by a high degree of technical difficulty. Because the seams on the back of the garment are flat and do not get loose, it is gentle on the skin and comfortable to wear, and is used in sports clothing, swimwear, wetsuits, corrective underwear, etc. Of course, it is not only suitable for athletic apparel, but also for casual parkas and baby underwear, with flat seams and specifications that are designed to be comfortable against the skin. Our company carries out integrated production from cutting to sewing finishing. We specialize in sports products, mainly cut-and-sew items, and we have 15 flat seamers, so we can accept large orders. Features of flat seamer sewing machine
This is a flat seam seam. Generally, it is a 4-needle stitch. The seams (the part that is sewn together) of a flat seamer sewing machine are very similar to those of a flat three-needle sewing machine, but the back side (the part that looks black) of the seam (the part that is sewn together) does not swell, and the cross section is flat. Finished in condition. How to sew flat seams There are two ways to sew flat seams. One is to sew the pieces together using just a flat seamer sewing machine. The other method is to sew the pieces together using a two-thread overlock sewing machine (overlock sewing machine), then open the sewn fabric from the front to make it flat, and then sew it together using a flat seamer. At Sewing Factory Miyamori, we will show you how to sew using two types of sewing machines: a double thread overlock sewing machine and a flat seamer sewing machine. Seam ①
← Sew the fabric together using a two-thread overlock sewing machine. Seam ②
← The part sewn together from the front side of the fabric using a two-thread overlock sewing machine is left open. When you open the seamed part, the two-thread overlock sewing machine will have the edges of the fabric facing each other. (It will be in a flat state) You can see the difference if you compare it with “Three-thread overlock sewing machine seam ① – Front side”. Seam ③
←　View from the outside of the fabric Sew together using a two-thread overlock sewing machine, then stitch (red thread) using a flat seam sewing machine from above the open fabric. Since it is sewn with 4 threads, the seams are well reinforced. *Stitch (red thread) In order to make the thread easier to understand, the top thread is omitted. If you use a decorative thread, the spaces between the needle threads will be reinforced with the decorative thread, just like the seams on the back side. Seam ④
← View from the back of the fabric Since the seam (seam allowance) of the overlock sewing machine is not turned to the left or right, the seam on the back side does not swell when stitched (red thread) and remains flat. It will be finished. You can understand this by comparing it with the photo of “Flat three-needle sewing machine seam ② – Back side”. Features of flat three-needle sewing machine
This is a finished cross-section of a seam on a flat three-needle sewing machine. If you look at the seams (parts that are sewn together), you can see that they were sewn together using a three-thread overlock sewing machine (overlock sewing machine), and then stitched (red thread) using a flat three-needle sewing machine, etc., where the seams (seam allowances) were folded down. It has been done. The seam allowance (the part that is sewn together) on the back side is swollen. Three-thread overlock sewing machine seam ① – Front side
If you sew them together using a three-thread overlock sewing machine (overlock sewing machine) and open the sewn part from the front, it will look like the photo. Three-thread overlock sewing machine seam ①-back side
This is the back seam when using a three-thread overlock sewing machine. The yellow part is the suture. Seam ② of flat three needle sewing machine – front side
Stitching (red thread) from above seam ① using a flat triple needle sewing machine. Seam ② of flat triple needle sewing machine – back side
The back side after stitching (red thread) with a flat three-needle sewing machine from above seam ①. The seam (seam allowance) that is sewn together with a three-thread overlock sewing machine (overlock sewing machine) is sewn with the seam turned to either the left or right, so the seam (seam allowance) will bulge out in the stitch thread on the back side.
