Abstract:
1. Method for automatically binding book blocks by machine in one working cycle, characterised in that a) the book blocks to be bound in an input station are clamped in series onto a conveying means fastened to a continuous support rail, and are transported through the individual treatment and processing stations in an upright position in time with the processing cycles; b) in a fanning glueing binding station glue is applied from below onto the book block spine, whereby applying the glue is performed by a press-on device so that the sheets of the book block on their spine are fanned in the one and subsequent thereto in the other direction and at the same time glue is applied to the fanned spine of the book block; c) in a spine-taping station the spine-taping material is applied onto the spine of the book block and is glued thereon, the spine-taping material is pulled-off from a roll and is automatically cut to the predetermined measure by machine; d) within a station for applying a headband the headband is applied onto the passing book block and is pulled-off from a roll according to stored data, is cut to the predetermined measure, the cut-off headband section is transported to the book block by means of a slide and is ironed onto the book spine; e) within a station for opening the end paper the book block provided with the headband is opened at the book block for subsequently applying the book cover in such a manner that the end paper of the book block is withdrawn from the transport press by a suctioning effect, and can be firmly clamped by a press engaging the book block in its lower area; f) within a book block station and with opened end paper the book cover is applied and is fixed to the book cover, whereby the end paper is bonded to the cover by heating and gluing; g) within a rounding station the book is released from the transport press and is engaged by bamd clamping devices located on both sides, the book block is supported by means of a loop or similar support means located between both clamping devices, and is rounded by a laterally advanced shaped member, and subsequent thereto the book block is transferred to the transport press again by said band clamping devices, and h) in a banding station the book provided with the cover and rounded on the spine is banded so that the rounding given the book is permanently fixed by maintaining the rounding within the book until the layer of glue is cured.
