Abstract: A glue cartridge (130) comprises a glue tank (101), a rotatable glue spreading roller (104) connected to the glue tank, which is arranged directly below the glue tank (101) and at least one rotation means (106, 107) usable from outside the glue cartridge (130) for rotating the glue spreading roller (104). The glue spreading roller (104) of the glue cartridge is designed so that the form of the glue spreading roller (104) prevents glue from escaping from the glue tank (101) when the glue spreading roller (104) is in place and takes glue from the glue tank (101) when the glue spreading roller (104) is rotated. A block (1360) of sheets to be bound to form a book is set in a bookbinding device (1300), and glue is spread on the spine (1362) of the block (1360) in such a way that glue is obtainable from an exchangeable glue cartridge (130) by using a receiving unit (150) for the glue cartridge (130).

Abstract: A machine (10) for fastening sheets comprises a) a fastening platform (11, 12, 13), which i) comprises a support surface (12) inclined with respect to the horizontal plane (x-y) which optionally also comprises extension means for the support surface, and ii) comprises an alignment surface (13), which is located at the bottom edge of the support surface or lower than this, in such a way that the intersection of the plane formed by the support surface and the plane formed by the alignment surface is formed, with respect to the support surface, by a threshold (100) extending along the width of the support surface, and b) a fastening unit (14).
