    Patent number: 7404871
    Abstract: The invention relates to a method and device for hot—gluing a bundle (2), particularly in a device that includes a glue reservoir (7) for storing a glue that has been made fluid, a glue-spreading roller (6) for spreading the glue onto the spine surface of the bundle (2), press devices, (3,4,5,2 1, 21?) for holding the bundle (2), and possible side-nip devices (16, 19, 20) for finishing the shape of the book. The bundle (2), which is held between two symmetrically positioned press plates (21, 21?), is pressed with the glue-spreading roller (6) to bend or fan out the edge of the bundle (2) and to open a gap between the cover sheet (11) and the outermost sheet of the bundle.
