What is a Bindery Hanger?
A bindery hanger (see diagram 1) is a short, folded piece of tag stock glued to the back panel of a folder or saddle stitched book which allows the piece to be saddle stitched between any signature of a saddle stitched book. The bindery hanger becomes a signature and therefore does not have to be glued to any signature of the saddle stitched book. A bindery hanger’s height is no greater than the spine or folded edge of the piece to be bound-in, and its width is usually at least four inches to as wide as the face trim of the product being bound. An additional three-quarter-inch is added and folded to produce a stub onto which the insert is glued. Q: Does an insert with a bindery hanger affect the efficiency of a saddle stitcher? A: No, once the insert has been mounted on its hanger, it runs on a saddle stitcher as efficiently as any “normal” signature. Q: What are the benefits of using bindery hangers? A: There are a number of benefits. It provides the flexibility to position an insert
A Bindery hanger is a carrier used to place an insert (usually a booklet) into a saddle stitched book. The carrier is a short, folded piece of tag stock, to which an insert is attached with removable fugitive glue. The insert can be smaller than the book into which it is bound, or it can be as large as the book and take head, foot, and/or face trims when stitching. As such, it becomes its own 4-page signature that can be positioned anywhere between the other signatures in a saddle stitched book. What is Backbone Stripping? Backbone stripping provides the same benefits for perfect bound books that bindery hangers do for saddle stitching. Backbone stripping involves attaching a three-quarter-inch wide strip of tag stock to the spine of an insert leaving a one-half-inch overhang which binds into the publication with the other signatures. This method prevents the finisher from grinding off any of the piece during the binding process and, because it is usually perfed and fugitive glued, all
