Abstract:
A device supported by a frame of a bookbinding machine for applying and pressing a cover onto an inner book which is continuously transported in a feed direction F, comprising:a vertically-movable back pressing plate mounted on a support plate for pressing the cover on to the back of the inner book; horizontally displaceable side pressing bars mounted in bearings on the support plate for pressing against side faces adjacent to the back of the inner book; wherein the back pressing plate and the side pressing bars are drivable in a cyclical reciprocating movement H synchronously with the transported inner book while pressing against the inner book during forward movement and guided at a distance from the back during the reverse movement; an actuating arrangement for driving the cyclical reciprocating movement, including connecting rods which are coupled at their one ends to respective pivot points outside the support plate and are pivotally connected at their other ends to respective of said side pressing bars directly or via an intermediate transmission which moves with the support plate; and means for displaceably guiding the pivot points outside the support plate essentially along the feed direction F.
