Case Binding

Case binding (also known as hard cover binding or hardback binding) refers to the binding of a book in which a thick board cover is involved. The cover is non-flexible and is supported by a paper-back board, making it incredibly durable.

This process of binding involves a few steps, the first being the joining of the book's sections, this process is known as thread sewing. Just like many of the other binding processes, the book block is added, creating a book spine, which in turn allows the cover to be added.

The last process, is where the hardcover is applied, also referred to as casing-in. It involves pieces of the board being trimmed to the cover size and, lastly, being fed into the case-making machine.

The case-making machine then securely applies a cover to the pieces of board by applying an adhesive, creating a strong hardcover for the book.


The end product is very durable and unable to be bent, as it is encased by a hardcover, which makes it more robust than other styles of binding. The finished product has an exclusive look, which gives it a classy effect.
