ABSTRACT:
An apparatus for eliminating curls at the cut ends of fabric workpieces provides air tubes directed toward the curls so that air flow flattens the curls. The apparatus includes a device for generating air flow; a first tube connected to the device for generating air flow and having one end fixed to the presser foot of a sewing machine; a second tube connected to the device for generating air flow and having one end situated under the throat plate of a sewing machine; and a valve positioned between the device for generating air flow and the tubes. The first tube includes an opening facing the curls and a contact portion extending horizontally and overlapping the curled edge of the workpiece for contacting the curled edge when the presser foot is moved downwardly. The second tube includes an opening facing the curls. The pattern of air flow is switchable to one or both of the tubes depending on the configuration of the curls; that is, whether the fabric is outwardly curled or inwardly curled.
