Document Type and Number:
WIPO Patent Application WO/2011/155091
Kind Code:

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 to be sewed that comprises the convex curve part. A two-needle sewing machine (1) comprises a bed part (3); a column part (5); an arm part (6); a needle shaft (11) that is disposed on the leading part of the arm part (6); two sewing needles (13, 14) that are attached to the needle shaft (11); two horizontal rotary hooks (15, 16) that catch the respective needle thread loops of the two sewing needles (13, 14); and a conveyor member (21) that conveys a material to be sewed (40) in a direction approximately orthogonal to the bed part (3). On the two-needle sewing machine (1), the sewing needle (13), which is positioned in a location further from the column part (5), is disposed closer to the conveyance side of the material to be sewed (40) than the sewing needle (14) that is positioned in a location closer to the column part (5).
