This binding style has different copyrighted names such as Rollabind, Rolobind, Button bind…and others. The process is not patented! With the exception of a metal ring binder, there is no other binding system in the world that allows the user to add and subtract sheets! The “buttons” come in sizes up to 1” and in about 20 different colours. If you order black or white your order will be done quickly. Any other colour might take weeks waiting for the buttons.
We did a project once requiring 10,000 bound the “Rollabind” style. Each month we punched an additional 10,000 new sheets that were sent to 10,000 retail outlets. Each outlet was instructed to remove a certain page number and replace it with the new page (updated prices). Of course, the removal and adding sheets required no machine(s). The process ran flawlessly for months. If you want something different, think Rollabinding, something to add or remove sheets with, think Rollabinding.
