ABSTRACT:
In order to overcome especially large areas of obstacle between a carrier plate for a workpiece to be sewn and a tubular stud arranged at the underarm of a sewing head, the underarm is tiltably arranged as to be swung downwards from its working position. The axle about which the tilting of the underarm is carried out, is located in the area of the standard of the sewing head. Additionally the upper arm of the sewing head can be tilted upwards about the same axle. Separate individual tilt drives are provided for the underarm and the upper arm.
