Adhesive Binding
Probably the most commonly used for of adhesive binding used in bookwork is Perfect binding, although burst binding is used occasionally. In all cases, the type of paper used for both text and cover will affect the strength of the binding.
Perfect binding: Folded sections of text/images are gathered into blocks, which are then automatically passed into the binding machine. They are tightly held in clamps, spine down, and are moved across rotating cutting blades, which removes the folds on the spine to expose the edges of the pages. The book blocks, still clamped, move over rollers where hot-melt glue is applied to the spines. At the next station, the covers are applied to the still wet glue. Finally guillotining occurrs, completing the process.
Burst binding: In burst binding the book sections are pierced along the spine with slot perforations during the folding operation. The sections are then collated and bound by a method similar to that used in perfect binding. The only difference is that the spine of the book is not removed; instead, glue is rolled onto the spine and forced through the perforations so that the book is securely held together. The cover is then applied to the still wet glue on the spine.
