Abstract
A sewing machine related to the present invention comprises a needle plate and feed dogs. A second feed dog slot provided at the cloth send-in side of a portal shaped needle hole of the needle plate is shifted to the right side from the center of the portal shaped needle hole. The left side first feed dog slot is extending toward the second feed dog slot side in the cloth send-in side of the portal shaped needle hole, so as to be formed a wide breadth portion from side to side. A first cross-piece of the needle plate is disposed between the wide breadth portion and a needle drop portion of the portal shaped needle hole, and a second cross-piece of the needle plate is disposed between the second feed dog slot and said needle drop portion. The first cross-piece is formed wider in the cloth feed direction than the second cross-piece. A differential feed dog disposed in the cloth send-in side of the needle drop portion is composed in a shape combining each feed dog slots. Therefore the cloth can be fed so as not to deviate in the lateral positions of the cloth end, and the spacing margin between the outlet seam end and the seam is controlled at a specified level, so that a sewn product of excellent appearance is obtained.
