Abstract

The application of protective jackets comprised of paper to a book is facilitated by minimizing bending stresses in the jacket paper in the fold areas where the jacket is wrapped around the opposed longitudinal edges of the book cover in the course of defining jacket retention flaps. The stresses are relieved by the metered, uniform moistening of the fold areas of the jacket to thereby diminish the flexual strength of the paper fibers in these areas.
