ABSTRACT:
The disclosed signature handling apparatus is for use with a saddle conveyor which moves signatures with a folded edge up along a path through a series of stations. The apparatus transfers signatures from the saddle conveyor to the infeed conveyor of a signature trimmer in a smooth motion and without abrupt changes in speed or direction. The infeed conveyor to the signature trimmer is located in a plane parallel to and above the path of the saddle conveyor. The apparatus includes a tucker blade mechanism which contacts the folded edge of the signature from below the saddle conveyor. The tucker blade mechanism moves the signature forwardly and upwardly from the saddle conveyor as it moves in a vertical plane through a path which is oblique relative to the saddle conveyor. A gripper finger assembly grips the signature from the tucker blade mechanism and continues the forwardly and upwardly movement of the signature and simultaneously rotates it about an axis parallel to the saddle conveyor. When the gripper finger assembly grips the signature from the tucker blade mechanism, it has a component of motion parallel to the path of the saddle conveyor. The signature is released into the infeed conveyor of the trimmer when it has a component of motion which is perpendicular to the path of the saddle conveyor and in the plane and direction of the trimmer infeed conveyor.
