Abstract
In order to form stacks, of which each forms a book block, folded sheets are provided with an adhesive application or layer of adhesive before they are placed on one another. Said adhesive application is applied to the sheets adjacent to the folded edge of said sheets and extends in the direction of said folded edge which comes to lie in the spine of the book block. The adhesive can be applied as a continuous track or as a track which is interrupted multiple times, or else in a punctiform manner. The sheets are joined to one another in the stack by means of said adhesive application, with the result that they maintain their position within the stack during further transport of the stack.
