The two-needle sewing machine is designed to improve strength in convex curve parts by bringing a pair of stitches closer together when sewing an item. This machine features a bed part, a column part, an arm part, and a needle shaft located at the leading part of the arm. It includes two sewing needles attached to the needle shaft, two horizontal hooks that catch the respective needle thread loops, and a conveyor member that conveys the material to be sewn in a direction approximately orthogonal to the bed part. Notably, the sewing needle positioned farther from the column part is located closer to the conveyance side of the material than the other needle.

Additionally, Nishi's seam forming device and method aim to create seams with an attractive appearance while increasing tightening force and drastically preventing raveling. The seam is formed by two needles juxtaposed at substantially right angles to the sewing direction. It consists of a chain seam formed by a needle thread passed through one needle and a lock seam formed by a needle thread passed through the other needle. The loop of the needle thread forming the chain seam is passed through the loop of the needle thread forming the lock seam before tightening, ensuring a secure and aesthetically pleasing seam.
