A cover feeding device (1) for a bookbinding machine comprising

• book block grippers (2) that continuously revolve along a closed track and have a rigid inner gripping jaw (2 a) and an outer gripping jaw (2 b) that can be moved relative thereto and thereby clamp and move book blocks on a moving plane,
• a magazine (3, 3′) having lateral stops (6.1, 6.2) and in which covers (13) are situated,
• a separating device (7) for withdrawing the covers (13) from the magazine (3, 3′) along a withdrawal direction,
• a transport device (8) that is arranged underneath the moving plane of the book blocks (14.1, 14.2, 14.3) and feeds the separated covers (13.1, 13.2, 13.3),
• a scoring device (9) for scoring edges of a spine region of each withdrawn cover (13.3),
• a cover press-on device (11) for pressing the cover (13.1) against the spine of the book block (14.1),
• wherein the magazine (3, 3′) includes at least a first lateral stop (6.1) that is arranged such that it can be fixed transverse to the withdrawal direction (12) and against which different covers (13, 13.1, 13.2, 13.3), for book blocks (14.1, 14.2, 14.3) of different thickness are jointly placed, and
• wherein at least the magazine (3, 3′) is adjustable transverse to the withdrawal direction (12) such that an edge (17) of the spine region of the respective cover to be separated is withdrawn essentially in alignment with the rigid gripping jaw (2 a).
