ABSTRACT:
A sewing machine capable of performing a profile sewing in which a stitch is provided at a position spaced away from an edgeline of a workpiece by a predetermined constant distance to provide a predetermined margin. The sewing machine is provided with memory means which stores therein the needle position data. This data is transmitted to a sewing needle swinging mechanism so as to move the sewing needle to a position inwardly spaced away from the edgeline to provide the margin. The sewing machine is also provided with image forming means connected to the memory means for providing a visualized image of a stitching reference line on one of a surface of the bed and the workpiece fabric on the bed in accordance with the needle position data. The stitching reference serves as a guide line along which the edgeline is placed.
