Abstract
In the manufacture of a book, the book consisting of a cover and an inner book, the book cover is permanently shaped by the formation of folds in the articulation region thereof prior to being joined to the inner book. In the course of forming the folds in the cover, the covering material thereof is caused to undergo plastic flow and to be shaped so that beneficial stresses are created in the fold defining regions. The back of the cover may also be permanently shaped substantially simultaneously with the formation of the folds.
