Abstract:
In combination,a plurality of sheets of paper disposed one atop another to form a stack having top and bottom sheets and defining a binding edge of said stack, an opposite edge of said stack parallel to said binding edge, and a narrow binding margin on said stack adjacent to said binding edge; a document cover formed of a plurality of panels including a front cover panel located atop said stack above said top sheet and a back cover panel located beneath said stack and residing below said bottom sheet and having a margin portion located beneath said binding margin, and wherein another of said document cover panels is a narrow margin binding panel having a width no greater than the width of said binding margin of said stack and said front cover panel is formed of a separate sheet of material from said back cover panel and said narrow margin binding panel, and overlaps and is permanently secured to said narrow margin binding panel; and a stiff, resilient, elongated channel-shaped clasp of uniform cross section throughout formed with a pair of clamping jaws joined together and projecting outwardly from their junction to form distal tips that define a gap therebetween, and said jaws are oriented in opposition relative to each other and said distal tips are directed toward each other to form an angle therebetween of at least about forty-five degrees, and said binding edge of said stack, said narrow margin binding panel, and said margin portion of said back cover panel are inserted in between said jaws with the remainder of said stack and document cover projecting through said gap so that said distal tip of one of said jaws is engaged with said narrow margin binding panel to restrict relative movement between said clasp and said stack in a direction perpendicular to said binding edge.
