A coupling device facilitates coupling of an ink transfer roller in an inking unit or printing unit of a printing machine. The ink transfer roller includes at least a roller body to which an end pin is connected, with each end pin of the roller being mounted to rotate in a bearing housing of the inking unit or printing unit via at least one bearing. The end pins of the roller include couplings with which the roller can be coupled and fastened in the inking unit or printing unit, with at least one end pin of the roller being splined to a shaft piece of a drive. The coupling device includes an actuator, with which at least one end pin of the ink transfer roller can be positioned against the shaft piece of the drive.

A flexographic printing machine including at least one printing unit with an ink roller mounted at one end to a first sliding support and a plate-holding roller mounted at one end to a second sliding support, and at least one guide member for guiding the movements of the supports in directions parallel to an imaginary line which perpendicularly intersects the axes of the ink and plate-holding rollers. In addition, first upper and lower screws are provided parallel to said line above and below the axes of the ink and plate-holding rollers in order to move the first support, and second upper and lower screws are provided parallel to the line above and below the axes of the ink and plate-holding rollers in order to move the second support.

A cylinder of a printing press is mounted using a bearing block. A radial bearing is movable in spaced linear bearings along an adjustment direction of the cylinder. The bearing is embodied as a modular bearing unit which may be a one piece assembly. The linear bearing is included in the modular assembly which permits movement of the bearing block along with the radial bearings.

A printing press is comprised of at least one printing cylinder. A displaceable inking unit and a displaceable plate changing device can alternatingly be placed against the printing cylinder or can be moved out of contact with it. The inking unit and the plate changing device are coupled together so that their respective displacements are accomplished by a common drive. The two move in opposite directions with respect to the printing cylinder and may be connected together. Alternatively, each may have its own drive, with the two drives being coupled together by a common controller.

A roller support apparatus includes a compression coil spring, lever, bias canceling member, roller holder, and support. The compression coil spring biases the distribution roller in a direction to come close to the oscillating roller. The lever transmits a biasing force of the compression coil spring to the distribution roller. The bias canceling member cancels bias of the compression coil spring. The roller holder rotatable supports the distribution roller and pivots in accordance with movement of the lever. The support is provided to the roller holder and engages with a shaft portion of the distribution roller. The support brings the outer surface of the distribution roller into contact with the outer surface of the oscillating roller in accordance with pivot motion of the roller holder.

A roller moving apparatus includes a pair of inner frames removably supported in a frame; a supportive holder member for supportively holding the roller; and a supportive holder member moving mechanism supported by the inner frames and adapted to support the supportive holder member and move the supportive holder member between a first position and a second position, the first position being either a position where the roller is attached to support members, or a position in the vicinity of the roller supported by the support members, and the second position being a position where the roller is supported on the inner frames. The inner frames have respective guide surfaces for guiding movement of the roller between the second position and a third position in the vicinity of an end surface of the frame.

A structure for attaching a sensing element for measuring load on a vehicle to a slide plate can reduce the number of components and gives good detection sensitivity. Mounting holes are made at an angle of about 20.degree. at both ends of an internal curved surface of the slide plate. Sensing elements each is secured in each the mounting holes. A wiring plate is placed centrally on a concave portion of the internal curved surface of said slide plate and is used to integrate lead wires from the sensing elements and extend them externally. The wiring plate and lead wires are molded.

A rubber roller in a printing press inker or dampener is force loaded against its adjacent rollers with hydraulic cylinders. The bearings of the adjacent rollers are fixed in the machine frame, while the position setting sockets of the rubber roller are supported on the hydraulic cylinders. The rubber roller can be thrown on and off by actuating the hydraulic cylinders and the loading force can be adjusted by the hydraulic pressure in the hydraulic cylinders.

A sheet-fed rotary offset printing machine accomplishes multi-color printing. A central impression cylinder carries sheets to be printed as they pass by at least two serially located blanket cylinders. These blanket cylinders are provided with ink images from cooperating plate cylinders. A sheet is gripped only once by grippers of the impression cylinder and is held in this single gripping operation during printing. At least one short inking unit is associated with each printing cylinder.
