摘要： A sheet conveying apparatus uses spaced, serially arranged suction chambers to provide suction to overrunning conveying belts. The belts are divergent with respect to each other in the direction of sheet transport to effect a lateral stretching of the conveyed sheets. The conveying belts are slidably supported on an upper surface of the conveying table and may have their speeds individually varied.

摘要： A method and apparatus for automatically feeding a printing plate to, or receiving a printing plate from, a printing plate cylinder in a rotary printing machine utilizes a plate storage compartment which is situated adjacent the plate cylinder. Several transport rolls are located between the storage compartment and the plate cylinder. A control computer is used to automatically actuate the transfer rolls, a drive for the plate cylinder and plate clamping and tensioning assemblies on the plate cylinder.

摘要： A sheet turn-over assembly includes at least one cooperating pair of first and second sheet gripper sets. Each set has coacting sheet gripper fingers and sheet gripper abutment surfaces. These fingers and abutment surfaces in each set are carried on coaxially aligned rotatable shafts. Movement of one shaft with respect to the other accomplishes sheet gripping and release. Movement of the coaxial shafts of each gripper set with respect to the cooperating set accomplishes sheet turn-over.

摘要： A mechanism for damping vibration in the gear drive of a rotary printing press is disclosed. The various gear driven elements such as transfer cylinders, forme cylinders and blanket cylinders carry belt pulleys with the pulleys being connected by suitable belts. The sizes of the pulleys are selected and sized to attempt to drive the various cylinders at a speed less than the speed provided by the gear drive. In this way the gear drive is not allowed to chatter or vibrate. The orientation of the drive belts is selected to conform with the number of gears in a particular gear drive assembly.

摘要： A clamping gripper assembly for use in a sheet transfer mechanism in a printing machine is disclosed. A gripper finger coacts with a gripper abutment surface with the gripper finger being spring loaded and secured to an oscillating gripper shaft which is provided with a flat face about a portion of its periphery. Oscillation of the shaft brings the gripping tip of the gripper into contact with the gripper abutment. A hinge joint is provided between the gripper finger and gripper shaft and allows pivotal movement therebetween.
摘要翻译： 公开了一种用于印刷机中的片材传送机构的夹持夹具。 夹持器手指与夹持器邻接表面共同作用，夹持器指状件被弹簧加载并固定到摆动夹持器轴上，摆动夹持器轴围绕其周边的一部分设置有平面。 轴的振荡使得夹具的夹持尖端与夹持器基座接触。 铰链接头设置在夹持器手指和夹持器轴之间，并允许它们之间枢转运动。
