A sheet-gripping device for sheet-processing machines includes a sheet-gripping member with a sheet-supporting surface of non-elastic material and a counter sheet-gripping member with a counter sheet-supporting surface made of elastic material. The sheet-supporting surface of the sheet-gripping member is formed with a plurality of projections located in first and second rows which extend skew to one another whereby a high uniform effect is attained in holding and transferring sheets being processed in the grippers closed in a vertical direction.

Sheet gripping arrangement

A sheet gripping arrangement of a rotary printing machine has a sheet gripper abutment member, a soft gripper seat member, a gripper shaft having a gripper shaft pivot point, a sheet gripping element including a gripper finger cooperating with the gripper seat member and eccentrically pivotable relative to the gripper shaft about a gripper finger pivot point so as to move first over a substantially flat gripping path and then to move during its final movement phase normally to the latter, and a threaded abutment member arranged in the finger member and acting against the sheet gripper abutment member, wherein the gripper finger member is arranged at an angle of substantially 90.degree. to a contact point of the threaded abutment member with the sheet gripper abutment member, to the gripper finger point, and to the gripper shaft pivot point.

Sheet gripping jar arrangement

A bearing arrangement for cylinders utilized in printing machines serves for supporting a cylinder trunnion in a machine frame. The bearing arrangement is composed of a sliding bushing surrounding the cylinder trunnion, a flange bearing supported in the machine frame and encompassing the sliding bushing. A second bushing is mounted between the flange bearing and the machine frame which has an outwardly radially extending central collar arranged in contact with the internal axial bore of the machine frame and two bonding elements inserted between the spaces in the second bushing formed by said collar and the axial bore of the frame for compensation of misalignment between the bearing and the machine frame when the cylinder trunnion is inserted into the frame.

Bearing for the cylinders of printing machines

A journal bearing of printing machines for permitting compensation for misalignments between a trunnion and a sliding bushing by means of a flanged bearing sleeve. The flanged bearing sleeve is provided with a plurality of grooves each being in engagement with a wedge which is movable therein, thereby achieving a compensation for misalignments.
