In a sewing operation wherein a stationary sewing machine is positioned adjacent one side of a movable table, the table having a smooth top which is adapted to receive a drapery fabric to be sewn, wherein a stationary buckrum dispensing device is supported adjacent the sewing machine so as to feed a strip of buckrum past the sewing head of the machine, the sewing machine being operative to sew the strip of buckrum to one edge of the fabric as the table conveys the fabric past the sewing machine, and wherein the table has a clamp mounted on the top thereof for releaseably securing an opposite edge of the fabric, the improvement comprising an elongated bar pivotably mounted above the table top adjacent and extending along the one side thereof, the bar being pivotable between a first position spaced from the table top to permit positioning of the fabric thereon and a second position in contact with the table top for holding the fabric while it is being sewn and for providing a reference line which may be used to indicate whether the table is moving faster or slower than the sewing machine. The improvement further comprises positioning the buckrum dispensing device on the throat side of the sewing head so as to feed the buckrum past the sewing head so that the stitches lie adjacent the side of the buckrum which is closest to the opposite edge of the fabric.
