ABSTRACT:
This invention relates to a device for protecting the edges of a book. An elongated, flexible material has a zipper located along the center of the elongated axis. The zipper, which may be of the plastic pressure lock type, connects two elongated halves forming the flexible material. On the outer edges of the flexible material is an adhesive bonding surface protected by an adhesive covering strip. In use, the adhesive covering strip is removed. The flexible material is then attached to the outer edges of the book by the adhesive bonding surface. To open the book, the zipper is unzipped, thereby allowing the book to be opened. To provide smooth corners on the book, notches are cut in the flexible material.
