Abstract
A system and method are provided for forming and implementing book binding geometries as a function of image receiving medium stack thicknesses for automated book binding in image forming devices. The disclosed schemes optimize book binding employing a plurality of strip-like binding elements to form loops in a process that employs heat and pressure to reduce residual stresses in the strips as they are formed into loops. The disclosed schemes mechanically modify a process of bending individual book-binding elements in a manner that more effectively employs less expensive material elements to provide consistent and durable “right-sized” book binding of finished documents. A combination of heat and pressure are introduced with a molded structure that results in controlling a radius of formation to be consistently followed by the “folded” binding elements in order to relieve the stress and preserve the integrity of those binding elements in the finished product.
