  • Patent number: 6599073
    Abstract: A simplified desktop book binder method and apparatus wherein the sheets to be bound are accurately aligned by the binder tape itself. In particular, the conventional binder tape is formed into an L-shape. Alignment is achieved since the inside corner of the L and the edge of the bundle of sheets of paper are in contact. The tape is dropped into a correspondingly shaped slot in the binder apparatus and the paper bundle is placed on top of the tape, the edge of the bundle being automatically aligned against the corner of the tape. The free end of the long leg is wrapped tightly around the paper bundle. In an alternative arrangement, a form is substituted for the bundle of paper, the form being covered with Teflon tape. Since the glue will not adhere to the Teflon, the form may be removed after binding leaving the covers and binding tape with glue inside the spine, thus allowing the user to make folders as desired.
