Abstract
A method and apparatus is provided for making books, brochures and similar products with a perfect binding. Signatures are continuously gathered in a specific sequence in a direction of conveyance, to form loose signature blocks. The loose signature blocks are collected by holders that include a mechanism that applies a compression force to the signature blocks. The signature blocks are transferred, with the compression force still applied to the signature blocks, in an approximately perpendicular feeding movement to a circulating clamping arrangement which is driven in the same direction as the direction of conveyance.
