Disclosed is a corrugated paperboard printer comprising a pressing device for applying a pressing force to press a chamber which reserves ink toward an anilox roll. The pressing device is configured to apply a first pressing force, and a second pressing force which is greater than the first pressing force, respectively, to a first pressing area and a second pressing area in a back surface of a chamber frame. In a state in which no pressing force is applied by the pressing device, bending occurring in the chamber frame due to a load transmitted from a printing roll to the chamber frame via the anilox roll as printing is performed to a corrugated paperboard sheet is greater in the second pressing area than in the first pressing area.

An ink fountain of an ink fountain device is provided with a fixed frame; a plate slidable on the upper surface of the plate; and an advancement and retraction mechanism advancing and retracting the plate with respect to the frame. The advancement and retraction mechanism comprises: a motor; a cam fixed to the output shaft of the motor which is integrally rotatable by rotation of the output shaft and has a cam surface shifted from an exact circle; and a rod in contact with the cam surface and advancing and retracting by the cam. The plate advances and retracts with respect to the frame by the advancement and retraction of the rod.

An ink fountain device having a base; a plate; an advancing and retracting mechanism for advancing and retracting the plate along an advancing and retracting direction; and a thin sheet arranged on the base which has plural holes accommodating balls and is thinner in thickness than a diameter of the balls. The plate is arranged over the thin sheet and supported by the balls.

A processing machine, in particular a printing machine, includes a unit having a storage container. The storage container comprises a roller and a base which delimit the storage chamber for a medium. One or more sliders are arranged along the edge of the base to form, together with the roller, an outlet gap for the medium. In the region of the one or more sliders, pneumatic means are provided to seal the supply chamber with respect to the medium. A method for operating such a processing machine is also disclosed.

An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration on a predetermined portion of a metallic container body. The decorator includes a sensor that senses decorations on metallic containers. A control system receives information related to the sensed decorations from the sensor and then determines if the decorations at least meet predetermined color, density, thickness, orientation, and consistency targets. The control system can automatically adjust elements of the decorator to correct a deficient decoration. In one embodiment, the control system can automatically adjust ink blades associated with a plurality of inking assemblies of the decorator to adjust the color, density, orientation, positioning, and consistency of decorations transferred to the metallic containers. In another embodiment, the control system can adjust a position of an inking assembly, an ink roller, a plate cylinder, a printing plate, a blanket cylinder, and a transfer blanket of the decorator.
