ABSTRACT:
The present invention relates to an automatic embroidery machine having a plurality of single-needle embroidery heads which are driven by a common main drive shaft. In order to also be able to produce drill patterns with such an automatic embroidery machine, a drill rod provided with a drill is arranged in each embroidery head, the rod being supported for movement parallel to the embroidery needle and being adapted to be driven from the main drive shaft by a transmission which makes it possible to stop the drill rod in the disengaged position. This transmission comprises a ring eccentric arranged on the main drive shaft and two carriages which are supported for displacement in a linear guide and can be coupled with each other, the drive carriage being connected via a connecting rod with the ring eccentric and the driven carriage being connected by a push rod with a central drive lever which actuates a continuous drive shaft for all drill rods.
