In an automatic sewing device the sewing head has, for producing a tangential path of the needle relative to the seam to be produced, a rotary housing which receives the needle bar and a likewise rotatable hook bearing which receives the hook and which can be tilt driven by an adjusting shaft at the same angle of rotation as the rotary housing. A drive shaft is provided for driving the needle bar and the hook. To enable even pivoting movements of the rotary housing in a simple embodiment without a change in the height of the needle bar occurring, there are provided a device for the drive-like connection of the adjusting shaft and the drive shaft and a device for the disengagement of the drive motor from the drive shaft.
