Abstract:
1. A method for pressing a book block having sides, a rounded back, and a longitudinal axis extending along the back, comprising: clamping the book block in between two clamping jaws on both sides of the book block in a region adjacent to the back and parallel to the longitudinal axis of the rounded back; moving a single pressing member perpendicular to the longitudinal axis with the use of a pressing device arranged vertically displaceable within a locally fixed frame to bring the pressing member against the rounded back of the book block approximately in the center of the rounded back; and subsequently moving the single pressing member along a preselected movement path across at least a section of the back to press the book block parallel to the longitudinal axis with the use of an actuator and a gear comprising two gear elements symmetrical to each other, operatively coupled to the single pressing member and horizontally adjustable by the actuator, wherein the single pressing member is movable vertically by the pressing device and horizontally by the actuator and gear to guide the single pressing member approximately parallel to the rounded back so that the single pressing member is movable along a preselected movement path corresponding to a curvature of the back of the book block while applying pressure onto the back of the book block.
