ABSTRACT:
An automatic buttonholing device which uses a specially modified presser foot into which electrical contacts are inserted for actuating an electromechanical buttonholing assembly. The operator places small conductive markers on the fabric at the top and bottom of the desired buttonhole location. When the contacts on the presser foot ride over the markers, a circuit is completed and proper steps in the buttonholing sequence are initiated.
