Abstract

The invention provides a sewing machine with uncurling device comprising a separating plate and a suction tube, the separating plate is placed in front of the needle drop point and it separates upper and lower fabrics fed to a needle drop point with their respective edge hems overlapped, and the suction tube has an air-intake with its size covering across upper and lower surfaces of the separating plate and it straightens curls at separated edge hems of the both fabrics by air flow sucked into the suction tube through the air-intake. As the overlapped edge hems of the both fabrics are fed into the needle drop point, the curls at the edge hems are reliably straightened regardless of the shape thereof. Therefore, it eliminates troublesome manual labor for straightening the curls before feeding of the fabrics.
