Comb Binding, also known as Cerlox binding or Surelox binding, makes use of a cylindrical plastic shape that has multiple curved tines along its length.
This rigid plastic shape forms the book's spine and would resemble a hair comb if it were not formed into a cylinder, hence the name Comb Binding.
Each tine or "tooth" along the comb binding element is pre-formed into a closed ring shape. Each ring-shaped tine contains tension. When these tines are spread apart and then released, the tension closes them back into a circular shape.
A comb bound book can lie flat in the open position without having to be held open. This feature makes it very well-suited for manuals, study guides, directories, cookbooks, and other reference materials that benefit from being "hands free."
Another advantage of a comb bound book is that pages can be added or removed relatively easily. Tabbed dividers and perforated pages also work well with the comb binding method. Furthermore, the plastic combs are readily available and come in a variety of sizes to accommodate books of varying thicknesses.
