Abstract:
1. A machine for attachment of a cover to a book block, comprising: a frame; a press plate attached to the frame to be vertically reciprocated between a lower standby position and an upper press position; a press plate elevating mechanism attached to the flame for elevating the press plate; a pair of nip plates disposed in parallel to each other on an upper surface of the press plate to be slid toward and away from each other; a nip plate drive mechanism attached to the press plate for sliding the nip plates; a clamp unit mounted on the frame for clamping a book block at both side thereof in such a way that a back surface of the book block to which glue is previously applied is directed downward, the clamp unit positioning the book block above a gap between the plates in such a way that the back surface of the book block is opposed to the gap, a cover being arranged over the press plate; and a controller controlling the press plate elevating mechanism and the nip plate drive mechanism, whereby the press plate together with the nip plates elevates from the lower standby position to an intermediate position adjacent to the upper press position, the press plate stays at the intermediate position during a waiting time for adjustment, the press plate together with the nip plates elevates from the intermediate position to the upper press position, and then the nip plates move toward each other so as to attach the cover to the book block.
