Patent

CA 2142180

A book binding apparatus and method secures pages of a document in a U-shaped channel. The apparatus (20) automatically adjusts its binding jaws (42a, 42b) the current size of the channel (86) prior to the binding force being applied to the channel. Operating forces generated by the apparatus in deforming the channel are limited by generating small amounts of deformation in the channel for each pull of an operating handle (22) to completely secure the pages into the channel. A debinding apparatus (30) and method, using the same operating mechanism as the binding apparatus, debinds the pages from the channel.

Dispositif et méthode de reliure des livres permettant de fixer les pages d'un document dans une pièce en forme de U. Le dispositif (20) ajuste automatiquement les mâchoires de la reliure (42a, 42b) à la dimension de la pièce en U (86) avant que la force de retenue ne soit appliquée sur cette pièce. Les forces nécessaires au fonctionnement produites par le dispositif lors de la déformation de la pièce en U sont limitées en imprimant de petites déformations à la pièce en U pour chaque traction d'une poignée de manoeuvre (22) en vue de fixer complètement les pages dans la pièce en U. Un dispositif (30) et une méthode utilisant le même mécanisme de manoeuvre que le dispositif de reliure sert à libérer les pages de la pièce en U.
