WORK PIECE CLAMP FOR A SEWING MACHINE FOR PRODUCING A SEAM OF TACK STITCHES IN A BUTTONHOLE.

Abstract This invention relates to a work piece clamp (1) for a sewing machine (5) is provided for producing a seam of tack stitches on a buttonhole (85) which extends in a longitudinal direction. Actuating the work piece clamp (1) and performing a motion of contraction of the pressure feet (14) which extends crosswise of the longitudinal direction takes place by means of a single lever which is part of a gear of simple design. Setting the pressure-foot position is enabled to be adapted to the width of the seam of tack stitches that is to be produced, and the extent to which a motion of contraction is performed on the pressure feet (14) is enabled to be adapted to the properties of the respective work piece (86).
