Comb binding uses a plastic spine with rings that can be opened to add or remove pages. Double-loop wire binding uses a metal wire closed with a wire closer; pages lie flat and can't be edited once closed. Some machines take interchangeable dies for both. Below, the binding machines in our catalog grouped by the binding types their makers list.
