Comb Binding

The spines used for Comb Bound books contain a row of tines, and each tine is curved into a circular shape. To bind a book, the tines are spread open and inserted through slots punched in one edge of the book's cover and pages. When the tension in the tines is released, the tines spring back to their original circular shape which entraps the cover and pages but still allows them to turn freely.

By the way, the plastic spine would resemble a hair comb if the circular tines were opened and pressed flat, hence the name "Comb" Binding.

Sometimes referred to as "GBC Comb" or "Cerlox", the comb binding method enables books to open 180 degrees. Because this allows a book to lie completely flat when opened, it can be placed on a desk or table for reading. It does not need to be held open, leaving the hands free to perform other tasks.

Comb binding is a practical choice for a variety of binding applications. These include assembly and maintenance guides, repair manuals, flip books and presentation books, product and price lists, cookbooks, workbooks and study guides, bound sheet music, directories, training and instruction manuals, travel guides, and any other book that would benefit from the convenience of being able to lie flat for easier reference.

The plastic spines come in different diameters in order to bind books of varying thicknesses. The spines also come in a range of popular colors.
