Abstract

See full text

An assembly for use in combination with sewing machines for purposes of removing portions of stitchable material around which a buttonhole or other desirable design is sewn by the sewing machine. In one embodiment, the assembly is a kit which includes a support assembly, a material removal device positioned within the support assembly, and a driver connected to the material removal device to supply the necessary forces to remove portions of material. The kit assembly may be attached to a sewing machine without requiring any substantial modification thereof and, if properly positioned, will not interfere with sewing operations and the components associated therewith. The kit assembly may also be removed or disabled to allow the sewing machine to perform functions other than sewing buttonholes. In another embodiment, a portion disposal system is utilized to carry away and preferably contain the removed portions of material.
