A sewing device for producing fastening stitches and tack stitches in a workpiece is described, in which a sewing head is installed with a jogging mechanism laterally vibrating the reciprocating needle as to perform a zig-zag movement or a needle-feed movement while a continuous relative feed movement between the workpiece and the needle is produced by a control device. The control device includes means for maintaining the direction of the needle vibration and the feed movement, as the fastening stitches are produced.
