Spiel Introduces the New Sterling Digibinder Perfect Binder

ROUGHING AND NOTCHING

Most table top perfect binders, as well as some floor models, only notch the book. The Digibinder roughs the entire backbone AND notches. Notching blades are two small points that turn on a wheel and scrape the backbone of a book block prior to gluing. This creates what looks like a barber pole on the spine of the book block. The theory is that the glue will seep in better into these spiral gouges in the spine. Full roughing does the same--But to the entire spine! "The notching on this machine is the cherry on top of the cake, not the cake itself," declares Michael Spiel. "If you are just notching, you produce a very weak bind." This unique roughing blade prepares the entire backbone while producing next to no waste at all.
