MDT 076 P2 Abstract of The Disclosure A binder having a rectangular stiffener board and a sheet retaining assembly. The stiffener board is provided in its first surface with at least three spaced parallel channels medially located between the side edges of the board. Each channel defines a hinge line extending along the height of the stiffener board. The sheet retaining assembly is mounted on the first surface of the board adjacent to the channels but outside the medial section of the board where the channels are located. The binder thus structured allows the stiffener board to define front and rear cover of the binder interconnected by the medial section which is foldable conformingly about the retaining assembly.

MDT 076 P2 Abrégé - La présente invention a pour objet un relieur à feuilles mobiles incorporant un carton raidisseur de reliure de forme rectangulaire ainsi qu'un ensemble de retenue de feuilles mobiles. Le carton raidisseur en question comporte une première surface dotée d'au moins trois rainures parallèles et espacées, pratiquées dans sa région médiane et d'un bord à l'autre du carton raidisseur. Chaque rainure définit une ligne d'articulation sur la pleine hauteur du carton raidisseur. L'ensemble de retenue de feuilles mobiles est fixé sur la première surface du carton raidisseur, juste à côté des rainures, et à l'extérieur de la partie médiane du carton, où sont pratiquées les rainures. Le relieur à feuilles mobiles ainsi configuré permet le rabattement des couvertures arrière et avant par-dessus l'ensemble de retenue et de manière à en épouser la forme.
