Abstract
The invention relates to a device for adjusting a checking unit of a presser foot, used in a sewing or embroidery machine. A needle bar moves the presser foot towards a needle plate, using a spring which is connected in series. The checking unit intercepts the presser foot using a checking element of the unit, before contact is made with the work piece to be sewn and controls the movement of the presser foot until the latter touches the work piece. The checking element and the needle bar are both operated by a common drive and the bedding position of the checking element can be modified in relation to the needle plate.
