ARRANGEMENT FOR PERFORATING AND SPIRAL BINDING OF RELATIVELY THICK GROUPS OF SHEETS ABSTRACT OF DISCLOSURE A system for perforating the edges and then spiral binding relatively thick books at a rapid rate. The system overcomes the relative difficulty of perforating, as compared with spiral binding, thick books by splitting the path for the perforating step into two paths and perforating simultaneously on both paths. The perforated books are then placed on a transverse leg of the system so that they combine into a single row which is fed to the spiral binder.
