PROBLEM TO BE SOLVED: To provide an integrated feed sewing machine suitable not only for sewing a thick workpiece but also for sewing a thin workpiece.SOLUTION: In an integrated feed sewing machine 10, a bottom part 54 of an upper feed foot 24 for pressing a workpiece is fork-shaped, and at a portion between the fork-shape, a bottom part 36 of a presser foot 20 is accommodated for pressing the workpiece. That is, as the bottom part of the presser foot for pressing the workpiece is accommodated in a penetration part of the upper feed foot, it is relatively compact. Therefore, in a place near a binding part of a needle thread and a bobbin thread, the workpiece can be pressed by the bottom part of the presser foot. Thereby, when the needle thread is pulled upward, even when the workpiece is thin, the workpiece can be properly prevented from moving upward together with the needle thread, and occurrence of sewing shrinkage can be properly prevented. That is, according to the integrated feed sewing machine, sewing can be properly performed not only for a thick workpiece but also for a thin workpiece. |
