ABSTRACT:
A book block transport system having a plurality of block pincers continuously movable in a closed circular path, the block pincers comprising a supporting frame which includes a stationary internal clamping jaw. A swinging frame is rotatably suspended at one end from the supporting frame and has attached to the other end an external clamping jaw which is positioned so as to allow clamping of a book block between the internal and external clamping jaws. The internal and external clamping jaws are urged together by an elongated torsion bar spring. The swinging frame is rigidly attached to one end of the torsion bar spring and a cam lever is rigidly attached to the other end of the torsion bar spring. Movement of the external clamping jaw with respect to the internal clamping jaw is provided for by rotation of the cam lever. A cam follower positioned on the end of the cam lever fits within the groove of a stationary two-dimensional cam to provide for rotation of the cam lever. In one enbodiment of the invention the opening and closing of the external clamping jaw with respect to the internal clamping jaw as well as the exertion of the clamping force is provided for by the movement of the cam follower with respect to the groove in the cam. In another embodiment of the invention, a compression arm is integral with the cam lever. A drive rail is arranged on the side of the system opposite the internal clamping jaw to provide for movement of the compression arm with respect to the rail. The clamping force by the external clamping jaw is provided by movement of the compression arm with respect to the guide rail. Further movement of the external clamping jaw is provided by the cam lever moving within the two dimensional cam.
