Flatlock Seam
A special Flatlock sewing machine is used to sew flatlock seams. The machine fuses 2 edges of material together creating a smooth, flat seam. Most clothes are sewn with overlock seams. Overlock seams are a cheaper, faster and easier way to sew clothes with but it leaves a bulky uncomfortable seam in your clothes.
Flatlock seams leave a smooth surface, almost like there are no seams at all.
With more than 300 Japan made Yamato flatlock sewing machinese, Beta Textiles Co., Limited (BTEXCO) is one of the leading flatlock garment manufacturer in China.
