Abstract

An assembly for performing both material removal and sewing operations on a large piece of stitchable material from which a smaller piece is removed to form an opening around which the sewing machine provides stitches. The assembly includes an attachment having a kit detachable from but connectable to the sewing machine. The kit includes a base provided with a surface for supporting the stitchable material. A punch die is formed in the supporting surface with a circular punch die edge to define the size of the opening to be formed in the large piece of material. A punch tool having a proximal end cooperates with the punch die for removing the smaller piece of material from the larger piece of material. The punch tool also has a cylindrically-shaped distal end connected to the proximal end. The distal end engages the stitchable material before the proximal end and has at least one cutting edge which, as the tool is first moved relative to the punch die, cuts the smaller piece and removes a central portion thereof from the larger piece of material, leaving a surrounding section within the perimeter of the opening. With the central section removed, the punch tool edge at the proximal end of the punch tool then cooperates with the circular punch die edge to remove the surrounding smaller section from the large piece of material to form the opening.
