Abstract
Disclosed is a two-needle sewing machine that improves strength in a convex curve part by bringing a pair of stitches close together when sewing an item. A two-needle sewing machine includes a bed part; a column part; an arm part; a needle shaft that is disposed on the leading part of the arm part; two sewing needles that are attached to the needle shaft; two horizontal hooks that catch the respective needle thread loops of the two sewing needles; and a conveyor member that conveys a material to be sewn in a direction approximately orthogonal to the bed part. On the two-needle sewing machine, the sewing needle, which is positioned in a location distant from the column part, is disposed closer to the conveyance side of the material to be sewn than the sewing needle that is positioned in a location closer to the column part.
