Patent ID: 7404871

Claim:
A method for hot-gluing a bundle, which comprises sheets and a cover blank that initially surrounds the bundle on one side, and for manufacturing a book, particularly in a device that includes a glue reservoir for storing glue that has been made fluid, a glue-spreading roller for spreading the glue onto a spine surface of the bundle, press devices, including two essentially symmetrically positioned press plates for holding the bundle between them, and side-nip devices for finishing the shape of the book, in such a way that the bundle is pressed with the glue-spreading roller to bend or fan out an edge of the bundle, characterized in that the roller is also used to open a gap between the cover blank and an outermost sheet of the bundle and that the glue is spread to such an extent that a glue bead forms at the gap and at an opposite edge of the bundle and also at a bend in the cover blank, and that the glue bead is spread for a certain distance in the gap between the cover blank and the edge of the bundle, in order to form a glue bond during a subsequent side nipping.
