  • Publication number: 20220281709
    Abstract: A dual roll laminating film cartridge refill for a reusable cartridge loadable in a laminating machine. The refill includes a first roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. The refill includes a second roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. A first connector couples the first axial ends of the first and second rolls at a predefined gap distance. A second connector is independent from and spaced from the first connector, the second connector coupling the second axial ends of the first and second rolls at the predefined gap distance. The first and second connectors are uniquely shaped and asymmetrical to provide a keyed interface to the reusable cartridge.

  • Patent number: 6773216
    Abstract: A binding apparatus facilitates a convenient, one-stage load-and-close binding system. The apparatus has a base and a pivotable former door movable between open and closed positions. A series of hooks are provided to hold an open binder relative to the base for loading sheets onto the open binder ringlets. The apparatus has three former surfaces or bars, including parallel, opposed first and second former bars, as well as an adjacently-positioned third former bar oriented generally perpendicularly to the first and second former bars. Generally, the binding apparatus operates to squeeze a wire binder between the opposed first and second forming bars to close the wire ringlets. The free ends of the wire ringlets are maintained in proper alignment against the third former bar.
