The book block is made by gluing the block spine to the inside of the Binding back b attached, advantageously a tape, a braid or a hose-like Interlayer d is inserted.

In order to increase the mechanical resistance of the plates or to increase them To make the same resistance easier, you can use the plates a. inside with ribs Mistake.

For better adhesion of the intermediate layer d to the binding spine b one can give this inside a robbed surface.

Any decorative equipment, especially incrusted decorations, the cover parts can be used during their production without a noticeable increase in the production price obtain.
