<p>A machine for attachment of a cover to a book block comprises: a press plate (8) arranged for reciprocal vertical movement; a press plate elevating means; a pair of nip plates (9, 10) arranged on the press plate (8) for sliding; nip plate drive means; and a clamp unit (5) for clamping a book block (4). The clamp unit (5) arranges the book block (4) above a gap between the nip plates (9, 10) in a way that a back surface of the book block (4) with glue layer faces the gap. A cover (12) is arranged on the press plate (8). The press plate (8) is moved from a standby position to a press position and the cover (12) is pressed against the back surface of the book block (4), and the book block (4) is clamped by the nip plates (9, 10) together with the cover (12), so that the cover (12) is attached to the book block (4). The press plate elevating means comprises a first elevation unit for vertically moving a first end (X) of the press plate (8) located at a top edge side of the book block (4), and a second elevation unit for vertically moving a second end (Y) of the press plate (8) located at a bottom edge side of the book block (4). The height of each of the first and second ends (X, Y) of the press plate (8) at the press position can be set separately by separately controlling the first and second elevation units by the control section (30).</p> |
