ABSTRACT:
A book binding apparatus and method secures pages of a document in a U-shaped channel. The apparatus automatically adjusts the binding jaws of the apparatus to the current size of the channel prior to the binding force being applied to the channel. The 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, and by using multiple pulls of the handle to completely secure the pages into the channel. A debinding apparatus and method, using the same mechanism as the binding apparatus, debinds the pages from the channel.
