Methods of an apparatus for wrapping jackets around books

摘要

Paper jackets are automatically applied to hard cover books in a manner which provides a good fit between the jacket and book and insures against the jacket folds slipping free of the book covers during or immediately subsequent to jacket application. The books are supported with the covers opened outwardly, a jacket sheet is draped over the spine of the book, the jacket material is urged downwardly simultaneously from both sides so as to tightly conform to the book and the opposite edge portions of the jacket sheet are folded around the front edges of the book covers while applying heat to thereby define jacket flaps which slide inwardly when the book covers are reclosed.
