摘要:
A loose leaf presentation folder which has an outer cover with front and rear panels pivotable about a hinge line and an inner binder strip, which may either be a discrete component or part of the cover, includes a pair of narrow panels pivotable about a fold line. If discrete, the strip is affixed within the outer cover with its fold line superimposed on the hinge line of the cover. The opposed outer edge portions of the binder strip are provided with a plurality of transversely-spaced, metallic tabs. The binder strip and the tabs, disposed along one edge thereof, are each provided with a hole therethrough and along the other edge of the binder strip, each of the tabs includes elongated prongs which are bendable to fit through the hole in the opposite edge of the binder strip. In the manufacture of this folder, the metallic tabs are adhesively bonded along the opposed edges of a continuous binder strip, thereafter the tabs are die-cut to provide holes and prongs which form female and male loose leaf binder elements.
