The present invention relates to a flexible and durable bookbinding and to methods for making bound books. More specifically, the present invention relates to books that may withstand substantial and repeated perpendicular flexure along their spine. Among other advantages, these books demonstrate improved resistance to wear and tear and normal usage to remain intact.

A method for thermoforming synthetic paper is provided, more concretely for thermoforming holding strips of synthetic paper, the strips being used to produce sheet-holding devices of a specific configuration. The devices can be used in the assembly of sheet holders such as calendars, white sheet dispensers or information cards.

A media binder, comprising: a front surface board, at least one spine board, and a back surface board, wherein each board comprises an inwardly facing surface and an outwardly facing surface; a cover sheet wrapped around the outwardly facing surface of the spine board and a portion of a surface cover sheet, the surface cover sheet wrapped around the outwardly facing surface of at least one surface board and comprises a first marginal edge attached to the inwardly facing surface of the at least one surface board and a second marginal edge unattached to the inwardly facing surface of the at least one surface board; at least one spring clamp to secure physical media inserted between clamp edges of the at least one spring clamp; and a tension sheet attached to the at least one spring clamp and the inwardly facing surface of the at least one surface board.

A media binder has an inner assembly and a case assembly, The inner assembly includes inside boards pre-attached to a binding mechanism. Adhesive is placed on outward surfaces of the inside boards. The case assembly includes a cover sheet with at least one marginal edge attached to surface boards and at least one loose edge. To customize cover, a printed cover is inserted in-between the cover sheet and the surface board through an opening formed by the loose edge. The case assembly is then laminated. The laminated case assembly is combined with the inner assembly using the adhesive on the inside boards. A one-piece media binder has cover sheets wrapping around surface boards forming pockets. The surface boards are partially attached to paste downs. To customize cover, printed covers are inserted into the pockets, and the paste downs are then attached to the surface boards to seal loose edges.

A binding mechanism including a body portion having a flange opening extending therethrough. The body portion further includes or at least partially defines a body portion opening positioned adjacent a base end of the flange. The binding mechanism has a manually deflectable flange coupled to the body portion. At least part of the flange is insertable through the flange opening from a first side of the body portion to at least partially form a loop on the first side of the body portion. The at least part of the flange is alternatively insertable through the flange opening from a second side of the body portion opposite the first side to at least partially form a loop on the second side of the body portion. The body portion opening is configured to receive the flange therethrough to enable the flange to be positioned on either the first side or the second side of the body portion.
