The book body is then glued, the spine rounded, and lining applied. The book
cover is manufactured separately by wrapping and gluing a printed cover on
binder’s board. It is then attached to the body with and adhesive in a process
called casing in. The bound book is then clamped in a fixture until the adhesive
dries.
Perfect binding :The perfect binding process, used for producing books that
are usually described as softcover or paperback, is a fast and relatively low-
cost method. Since it eliminates the need for sewing and constructing a hard
cover, it is more economical than edition binding. Perfect binding is not as
long-lasting or rugged as edition binding. For this reason, it is often selected
for products that will have a limited lifespan, such as telephone directories,
magazines, and some books for children. Its low cost has made it popular for
mass-market novels and other books where price is a competitive factor.
In this process, either signatures or single sheets can be gathered or collated to
form the book body. The binding equipment then grinds or saws the binding
edge of the book body to roughen the surface, and a flexible glue is applied.
The cover is then placed on the body and clamped until the glue sets. The
book is then trimmed.
Mechanical binding : It consists of a number of methods that employ a
mechanical device (metal spring, plastic fastener, etc.) to hold sheets together
in loose-leaf form. Two of the methods usally used are plastic comb binding
and spiral binding.
Plastic comb binding:- It is commonly used for booklets that might have to be
altered by adding or removing pages. Books bound with this method permit
the pages to lay perfectly flat when open.
