Method and device for automatically binding book blocks by machine in a working cycle

This invention relates to a method and a device for automatically binding book blocks by machine. In a working cycle, the book blocks are conveyed on a conveyor device in an upright manner through the individual processing stations. In a fanning gluing binding station, adhesive is applied from underneath against the fanned book block spine. In a spine-taping station the spine-taping material is directly pulled off a roll and is automatically cut to the predetermined measure by machine. The headband is likewise pulled off a roll, cut to the required dimensions, advanced to the book block by means of a slide and is ironed onto the book spine. Afterwards, the end paper of the book block provided with the headband is opened in order to attach the book cover to the book block, is pulled from the book block by suction, and is clamped in a lower station press. With the end paper opened, the book block is then placed in a covering station, and the book block is fixed to the book cover. In a rounding station the book is detected by strip clamping devices located on both sides, and the book block is held by a loop located between both clamping devices and is rounded by a laterally advanced shaped member. The book, which is provided with a cover and whose spine is rounded, is banded in a banding station and the rounding given to the book is permanently fixed.
