Claim 12:
13. A machine for producing adhesively bonded printed products, comprising book blocks, the machine comprising:
a circulating clamp chain comprising binder clamps spaced apart from one another, each of the binder clamps being operatively connected to a respective clamp opening system, and each of the binder clamps being configured to circulate along a transport path between a loading location for receiving a book block of a current cycle and a discharge location for discharging the book block of the current cycle,
wherein for a binder clamp of the binder clamps, the respective clamp opening system comprises:
a moveable tab that is configured to be pushed toward an interior of the binder clamp by an outside force provided by at least one drive, the outside force being perpendicular to the transport path;
a toothed rack operatively coupled to the moveable tab, a holding system, a torsion spring, and at least a portion of clamping jaws of the binder clamp;
wherein the holding system comprises a latching ratchet,
wherein the at least one drive is configured to controllably apply the outside force to the moveable tab such that the moveable tab is pushed toward the interior of the binder clamp causing a corresponding translational movement of the toothed rack, the corresponding translational movement of the toothed rack being configured to pretension the torsion spring and configured to move at least the portion of the clamping jaws such that the clamping jaws are in a predefined open position,
wherein the machine is configured to controllably operate the at least one drive to apply the outside force based on a thickness of the book block to be received in the current cycle,
wherein machine is configured to operate the holding system to controllably fix the clamping jaws in the predefined open position, and
wherein the toothed rack is configured such that, in a clamping state of the binder clamp, the toothed rack transmits the pretention force of the torsion spring to at least the portion of the clamping jaw such that a pressing force is applied to the book block received in the current cycle.
