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.

Abstract: A low cost, high speed, high resolution laser printer method and apparatus for re-writable media is presented. A method for finishing of printed sheets into booklets is described. Novel mechanical operations permit the manufacture of a very low-cost, off-line booklet maker for use with desktop laser and ink jet printers. The technology can scale to medium-speed, in-line booklet manufacture. The method is novel because most of the finishing operations are performed on a sheet-by-sheet basis using precision paper positioning and a transverse tool carrier that cuts, scores, folds, punches, and staples the sheets. To form a finished saddle-stitched booklet, each sheet is cut to length determined by its sequence in the booklet and paper thickness, scored, punched (if required), folded, accumulated in a stack, and stapled. The sheet-wise method allows finishing operations to be done with low-cost tools and low actuation forces.
