Case Binding
Case binding is a book bound with a stiff, hard cover that is covered by fabric or other material. In case binding, most often used in book production, printed sheets are folded into 8, 16 or 32-page signatures, which are collated and sewn by machine. The sewn edges are coated with glue. Then a strip of gauze adheres to the document's spine. Finally, the book and its covers are placed in a casing-in machine, which pastes the endpapers and fits the cover.
