International Classification:

B42C 1102

US Classification:

412 19

Abstract:

A binder assembly system, without a metal spine but only paper or paper-like material at its channel spine (15), for binding together a series of sheet materials (20), using an "hard cover" book-like, single-piece binding cover (10), made up of a number of main, structural parts, including two, side boards (11A & 11B), a sheet (12) of book covering material, and a centrally located, special paper spine element (13), with an internal, paper cover (14) which over-lies the combined width of the side boards and the paper spine element, all of which when combined together form the book-like binder cover using pre-heating and forming step(s). The various cover parts are pre-assembled together in their respective positions. The channel area of the cover is first pre-heated to facilitate forming in the range from about one hundred and fifty to four hundred (. about. 150-400) degrees Fahrenheit and dwell times from about two to about thirty (. about.

Abstract:

A cover-less binder assembly system for binding together a series of sheet materials, such as, for example, paper for business reports and the like by an office worker, with the binding typically being done along one edge using a simple, cover-less and guide-less spine (10). A separate, temporary guide (20) is temporarily provided for initially guiding the sheet material or papers into the binding spine or member to be adhered thereto, after which the combination of the spine (with the edge-inserted sheet materials) and the temporary guide are placed in a heating unit for binding the sheet materials to the spine with hot melt glue. Thereafter the bound materials are removed from the separate guide, which can thereafter be re-used in connection with other materials to be bound and a different spine. A preferred guide member includes two diverging side panels (22) forming a "V" shape leading into a trapezoidal-shaped bottom in which the spine is positioned but otherwise unattached or connected. Exemplary variations in the temporary, separate guide member are illustrated in FIGS. 7 & 8.
