One of the most common and simplest types of book binding is stitch binding. In stitch binding, the individual sheets are first folded to the appropriate format and inserted into each other. Then the sheets and the cover are stapled from the outside at the folding points twice, three times or several times with wire staples.
Stitch binding is a very popular and old type of book binding. However, it is only suitable up to a book thickness of around 5 mm, otherwise the staples no longer hold together.
