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.
